At top there is some most useful info about foo.
Between horizontal lines there is some immediate actions, if they are available, to perform on/with foo.
And below is thing that bothers me. There goes tabbed, detailed information about foo.
Those tabs can hold some actions too and can be quite sovereign.
So the is - how to properly structure this thing (what should be controllers, actions, to each other) in order to avoid unnecessary hussle?
I'm confused cause those tabs below are like a separate island.
---
In model - there's that strange thing: 1 on 1 relation. It's like there's a `Contest` (Foo), and `Participant`. Tabs are detailed description of `Participant`.
Currently I've modeled them both as [aggregate roots](http://domaindrivendesign.org/node/88). But it might be a wrong choice.
So - if there are two roots, it seems natural if both of them got controllers and `Contest` isn't really responsible to hold all data.
It seems that sub actions would be the way to go, but I foresee some complexity. When tabs will hold some actions, they will need to know how to redirect back to `Contest` details and how to pass info how to render correct tab. This coupling I would like to avoid but it seems there's no way to do that.

[Getting a modified preorder tree traversal model (nested set) into a <ul>](https://stackoverflow.com/questions/1310649/getting-a-modified-preorder-tree-traversal-model-nested-set-into-a-ul)
The difference is that I have many trees in one table. Each row has a foreign key representing its parent and its top parent: category_id and root_id. Also I have the lft and rht fields based on this example:
[http://articles.sitepoint.com/article/hierarchical-data-database/2](http://articles.sitepoint.com/article/hierarchical-data-database/2)

How can I build an ordened list representing this tree?
With the sql bellow:
```
SELECT c. * , (COUNT( p.id ) -1) AS depth
FROM `categorias` AS p
CROSS JOIN categories AS c
WHERE (
c.lft
BETWEEN p.lft
AND p.rht
)
GROUP BY c.id
ORDER BY c.lft;
```
I got this result:
As you can see, I need to order by root_id too, so that I can generate the correct tree.
Also, after get the tree, is there a way to order each node by name?

### ADDED
VonC and Charles explained the differences between `git reset` and `git checkout` really well. My current understanding is that `git reset` reverts all of the changes back to a specific commit, whereas `git checkout` more or less prepares for a branch. I found the following two diagrams quite useful in coming to this understanding:

3,639,758 | 1 | null | null | 0 | 1,045 | I wrote a Jquery function that blacks out the screen after a certain amount of inactivity, creates a pop-up that allows the user to click a button to stay logged in, and logs them out (closing the application window) if they do not respond in time.
The environment is ASP.NET (VB). We don't technically use master pages, but we do have a parent page in which our header, footer and nav reside, and my Jquery code is called from that window, loaded via an IFrame.
We're using txControl's ActiveX version as our text editor built into the app. We're going to be upgrading very soon, but for now I've got this one classic ASP page that I need to integrate my timeout code into, but when the timeout code kicks in, the ASP file does not "black out" like the rest of the child windows, and the button to continue the session is invisible, ending up behind the ASP page, I'm guessing.
Here is my main timeout function, which is in a .js file and is inserted into the parent window via a script tag:
```
function pop_init() {
// show modal div
$("html").css("overflow", "hidden");
$("body").append("<div id='popup_overlay'></div><div id='popup_window'></div>");
//$("#popup_overlay").click(popup_remove); // removed to make sure user clicks button to continue session.
$("#popup_overlay").addClass("popup_overlayBG");
$("#popup_overlay").fadeIn("slow");
// build warning box
$("#popup_window").append("<h1>Warning!!!</h1>");
$("#popup_window").append("<p id='popup_message'><center>Your session is about to expire. Please click the button below to continue working without losing your session.</center></p>");
$("#popup_window").append("<div class='buttons'><center><button id='continue' class='positive' type='submit'><img src='images/green-checkmark.png' alt=''/> Continue Working</button></center></div>");
// attach action to button
$("#continue").click(session_refresh);
// display warning window
popup_position(400, 300);
$("#popup_window").css({ display: "block" }); //for safari using css instead of show
$("#continue").focus();
$("#continue").blur();
// set pop-up timeout
SESSION_ALIVE = false;
window.setTimeout(popup_expired, WARNING_TIME);
}
```
I've attached "stay-alive" code to mousedown, keydown and blur events in the child windows like this:
```
<script src="http://jqueryjs.googlecode.com/files/jquery-1.2.6.min.js" type="text/javascript" language="javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
window.parent.reportChildActivity();
});
</script>
<script type="text/javascript">
$(document).bind("mousedown keydown blur", function() {
window.parent.reportChildActivity();
});
</script>
```
I tried adding the following to my ASP file, only to get the result you see in the attached image:
```
<script src="http://jqueryjs.googlecode.com/files/jquery-1.2.6.min.js" type="text/javascript" language="javascript"></script>
<script src="JScripts/RC_jquery.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
window.parent.reportChildActivity();
});
</script>
<script type="text/javascript">
$(document).bind("mousedown keydown blur", function() {
window.parent.reportChildActivity();
});
</script>
```
Can anyone tell me what I need to do to get the Jquery timeout div to overlay the entire window as designed? Thanks for your time and any assistance you may be able to provide!
Top pic is the desired result, and the result on all the aspx pages. Bottom pic is what I'm getting on the classic asp page.
EDIT: Well, I thought to wrap all the essential parts of the ASP page in a div (called "divPage") and then hide the div. It works like a charm if I call "$('#divPage').hide();" from a script in the head section of the ASP file - it hides the div as soon as the document loads. However, I need conditional hiding, so I tried to put the same code in my Jquery file, in the pop_init function, and although the rest of the code in that function executes flawlessly for me, the code to hide divPage is doing nothing. Any ideas why I'd get different results from the iniline code, versus the function included in the RC_Jquery.js file?

because it added Bill to persons, but...because PersonID is not nullable, and it inserted him with id 0. When I tried add another person the same way of course I get error about primary key :)

There are some things that I can't work out:

3. Why the atoms also have the bond background applied

3,644,037 | 1 | 3,644,076 | null | 1 | 346 | I am trying to translate a function in a book into code, using MATLAB and C#.
I am first trying to get the function to work properly in MATLAB.
Here are the instructions:
The variables are:
```
xt and m can be ignored.
zMax = Maximum Sensor Range (100)
zkt = Sensor Measurement (49)
zkt* = What sensor measurement should have been (50)
oHit = Std Deviation of my measurement (5)
```
I have written the first formula, N(zkt;zkt*,oHit) in MATLAB as this:
```
hitProbabilty = (1/sqrt( 2*pi * (oHit^2) ))...
* exp(-0.5 * (((zkt- zktStar) ^ 2) / (oHit^2)) );
```
This gives me the Gaussian curve I expect.
I have an issue with the definite integral below, I do not understand how to turn this into a real number, because I get horrible values out my code, which is this:
```
func = @(x) hitProbabilty * zkt * x;
normaliser = quad(func, 0, max) ^ -1;
hitProbabilty = normaliser * hitProbabilty;
```
Can someone help me with this integral? It is supposed to normalize my curve, but it just goes crazy.... (I am doing this for zkt 0:1:100, with everything else the same, and graphing the probability it should output.)

3,644,734 | 1 | null | null | 1 | 604 | learning Cocoa can be pretty tough for web developers. Some things are so simple in HTML, and I have no idea, how to do this in Cocoa.
Let me just show you an image here, to show you what I have on my mind.
So it's kinda like a blog. Each post has variable length, so it can take up some space. Also, you're able to scroll through posts.
I was thinking about using or , but since I don't know much about Cocoa, I'm asking you for advice.
Also please do link any related articles.
So here are some things that I discovered.
1. I could make a subclass of NSCell and use it in Table View. I can use it, I can put there a string, something like this:
[http://pastie.org/1140412](http://pastie.org/1140412)
(please take a look at this code, I'm wondering if I should use awakeFromNib/setDataCell combination)
1. But string is not enough. I need a NSTextView. The problem is, it doesn't have method like drawInRect: withAttributes:. So I don't know how to draw it into that cell. I guess I'm missing some basics here, so I'm just gonna study some Cocoa views now.
Any ideas are welcome.

Can someone show me the correct way of dealing with this problem? A link of tutorial will be helpful thanks :)
This is the code that is use to generate the list of date as in the picture below
```
function test(){
var count = 0;
var date1 = $('#alternatestartdate').val();
var date2 = $('#alternateenddate').val();
var startDate = new Date(date1);
var endDate = new Date(date2);
var Weekday = new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday");
while (startDate<=endDate)
{
var weekDay = startDate.getDay();
if (weekDay < 6 && weekDay > 0) {
var month = startDate.getMonth()+1;
if( month <= 9 ) { month = "0"+month; }
var day = startDate.getDate();
var datearr = new Array();
if( day <= 9 ) { day = "0"+day; }
count++;
var datelist = day+"-"+month+"-"+startDate.getFullYear();
$('#pa').append(day+"-"+month+"-"+startDate.getFullYear() + " ("+Weekday[weekDay]+") <input type='hidden' id='' name='date_"+count+"' value='"+datelist+"' /><input type='hidden' id='' name='day_"+count+"' value='"+Weekday[weekDay]+"' /><input type='radio' name='period_"+count+"' value='1' checked/>Full<input type='radio' name='period_"+count+"' value='2'/>Half (AM)<input type='radio' name='period_"+count+"' value='3'/>Half (PM)<br />");
}
startDate.setDate(startDate.getDate()+1)
}
$('#pa').append("<input type='hidden' id='' name='countval' value='"+count+"' />");
}
```
If insert correctly, the data the in database will look like this:

I also have a UISearchDisplayController for searching the contents of the table view. The searching functionality will be able to delete items of the content displayed by the table view. So if the user chooses to delete one of the items they found while searching, I want to not only reload the UISearchDisplayController's table view but also the UITableViewController's table view. When I do that, the sections of the regular table view pop out and display above the UISearchDisplayController. It's really quite strange. I think the best way to explain it is with an image:

Some of my questions are:
What are the advantages or disadvantages of the later approach?
A situation where the initial or later model is better?
Does the initial model enable a friend to borrow a movie more than once?
Any thorough explanation would be much appreciated.

3,647,821 | 1 | 3,721,880 | null | 1 | 4,178 | In my Android app I use a TabWidget without any special customization. I'd like Android to take care of the specific appearance, which works fine if you compare Android 1.6 with 2.1 for example. By just using a TabWidget the same code leads to different forms of tabs because the SDK defines how to draw it.
Here is how it looks on 2.1 for example:
So, the highlighted tab is gray and the font is white and you can read it quite well.
But, if you have HTC Sense, it looks like this:
The picture isn't that good, but just believe me that it's white text on white background which is not really that easy to read...
My questions are:
1) Why does Android create a TabWidget with white on white text? I never defined either the text color or the background color, so the system is supposed to chose sensible colors.
2) I assume that other TabWidgets look just fine on HTC Sense, because otherwise it would be quite a big and popular problem. So why is my TabWidget having this problem and not others.
3) How can I fix this problem without changing the appearance on non Sense devices?
As I said I did not customize the TabWidget in any way. Here is my definition:
```
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@android:color/black"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="0dp"
>
<ScrollView
android:id="@+id/shortenerScrollView"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:background="@android:color/black"
android:fadingEdge="horizontal"
>
```
So, besides defining black as my general background color of the app, there's no color or style defintion made. The only exception might be that I'm using standard Android ids for TabHost and TabWidget.
/Edit:
Here's the defintion of the tabs in the onCreate method:
```
th = getTabHost();
th.addTab(th.newTabSpec("shortener").setIndicator(getString(R.string.tabShortenerName),
res.getDrawable(R.drawable.url_zip)).setContent(R.id.shortenerScrollView));
```
The class extends a TabActivity.
/Edit 2:
The device that comes up with the white on white text is a HTC Legend running Android 2.1 btw.
/Edit 3:
dream3r was right. Changing the targetSdk value to 4 did the trick for me, too (before, it was set to 6)! I don't really get it, but I can live with that for now. :)
Here's a picture of how it looks now:

I am using this:
```

Dim directory As String = appPath & "/upload/" & Left(TableName, 2) & "/"
```
to get the path and it's working very well.
But when I create a new sub-folder and copy some pages from the root directory into the sub-folder, my images are not displayed because the path has changed.
This is the link from the page in the root directory:

and this is the link from the page in the sub-folder:

So how can I make the link in the sub folder like this:
> [http://www.lebmotor.com/upload/VE/TN/6/VEListing-66-Photo1.jpg?ts=9/4/2010%201:45:17%20AM](http://www.lebmotor.com/upload/VE/TN/6/VEListing-66-Photo1.jpg?ts=9/4/2010%201:45:17%20AM)
---
Let me explain more about this. First, I have two directories and both of them have been set as application directories, as you can see here in the photo:
The `/ar` sub-folder is an application and it's a copy of the original one in the Content directory.
In the `ar/App_code` there is a class with the name `MGImages.vp`, and course it's a copy of the original one in `Content/App_code`. This class' job is to display photos from the `Upload` sub folder.
This is the code which will save the path of the photo:
```
Dim appPath As String = HttpContext.Current.Request.ApplicationPath
Dim directory As String = appPath & "/upload/" & Left(TableName, 2) & "/"
If ImageType.ToUpper = "TN" Then
directory += "TN/"
ElseIf ImageType.ToUpper = "LG" Then
directory += "LG/"
Else
directory += "OT/"
End If
```
This class is working very well in the `Content` directory because this will give me the right path:
> [http://www.lebmotor.com/upload/VE/TN/6/VEListing-66-Photo1.jpg?ts=9/4/2010%201:45:17%20AM](http://www.lebmotor.com/upload/VE/TN/6/VEListing-66-Photo1.jpg?ts=9/4/2010%201:45:17%20AM)
All photos should be saved in the `Content/Upload` folder for both directories' `Content/ar`
But in the `ar` directory it will give me the wrong path:
> [http://www.lebmotor.com/ar/upload/VE/TN/6/VEListing-66-Photo1.jpg?ts=9/4/2010%201:45:17%20AM](http://www.lebmotor.com/ar/upload/VE/TN/6/VEListing-66-Photo1.jpg?ts=9/4/2010%201:45:17%20AM)
Where the goal is to make the path like this one:
> [http://www.lebmotor.com/upload/VE/TN/6/VEListing-66-Photo1.jpg?ts=9/4/2010%201:45:17%20AM](http://www.lebmotor.com/upload/VE/TN/6/VEListing-66-Photo1.jpg?ts=9/4/2010%201:45:17%20AM)
I want it to display the photos from `Content/upload`, not from the `content/ar/upload`.

well normally when we click the Drop Down Menu... we navigate to another Page but since i am not switching to another page...
what happens is when i click a menu item it performs the JS but doesn't collapses, that is, it stays in the
following is an screen-shot after a click
which is logical because the cursor is still there and when i will move the cursor it will go back to collapse state but i want to change its behavior such that when i click it collapses...
ONE WAY is that when i click and the `#myDIV` is loaded with the required div... i load the Drop Down Menu Layer with itself (reload it)...

Basically I have a model `Action`, (which gets created anytime a user does something that affects another user, like commenting on their article or voting on someones photo, for example), these actions will be listed in the users dashboard page as all the actions that have taken place that relate to them, like a stream... sort of like Github's "News Feed"
I've decided to go with creating a polymorphic association, here is what my model looks like:
```
class Action < ActiveRecord::Base
belongs_to :instigator, :polymorphic => true
belongs_to :victim, :polymorphic => true
end
```
I used instigator and victim because anyone can create these actions, which in turn always affect another user, here is my `User` model
```
class User < ActiveRecord::Base
has_many :actions, :as => :instigator
has_many :actions, :as => :victim
end
```
And this is where I'm going wrong, because ultimately I want to have a query which when I run something like `User.find(1).actions` to actually return all the instances in which the user is both an `instigator` or a `victim`, I think I can't have both of those `have_many`'s in there, because when used like this I only get the instances where the user is the `victim`.
Here is my migration:
```
create_table :actions do |t|
t.references :instigator, :polymorphic => true
t.references :victim, :polymorphic => true
t.string :action_performed
t.references :resource, :polymorphic => true
t.timestamps
end
```

3,648,926 | 1 | 8,438,768 | null | 0 | 2,078 | I just started using Aptana Studio. The first thing I did was import my php from svn repository and install the PDT tools. But whenever I open the php file, it always displays following message.
I had the PHP perspective open when I tried opening the file. Also I checked the Content Types and File Associations, where PHP Content Type has `*.php` listed and `*.php` had the `PHP Editor` associated with it in the file associations.
I even tried creating a new PHP project, then creating a new PHP file - couldn't even do that - nothing showed up.
What am I missing over here?

On some site, I found some friends said that this is because my original string is too short, `GZIPOutputStream` can be used to compress longer strings.
so, can somebody give me a help to compress a String?
My function is like:
```

```

I've set the project to register for COM interop, and I've registered the DLL with:
```
regasm.exe /tlb NLog4VBA.dll
```
When I open Excel, I go to Tools -> Add-Ins, click Automation, and add NLog4VBA.Logger. I can then go to Insert -> Function, pick NLogVBA.Logger from the list of categories, and choose Debug.
The end result is a cell with contents like:
```
=Debug("My Context","My Message")
```
... and a displayed value of:
```
10
```
This is all as it should be. In my VBA code, I can go to Tools -> References and add NLog4VBA. I then add the following code to a button on my sheet:
```
Private Sub CommandButton1_Click()
Application.COMAddIns("NLog4VBA.Logger").Object.Debug "My Context", "My Message"
End Sub
```
This fails, because COMAddIns("NLog4VBA.Logger") fails with:
```
Run-time error '9': Subscript out of range
```
Could someone please tell me what I need to do to make the Debug() method accessible to my VBA code (which is more useful to me than being able to call the method from within a cell)?
I'm sure I'm missing something simple here.

The code is as follows:
```

conn.Open();
using (SqlCeDataAdapter adapter = new SqlCeDataAdapter(
"SELECT * FROM People", conn

"WHERE id = @id", conn);

"@name", SqlDbType.NVarChar, 100, "name");
SqlCeParameter idParameter = adapter.UpdateCommand.Parameters.Add(
"@id", SqlDbType.Int);
idParameter.SourceColumn = "id";
idParameter.SourceVersion = DataRowVersion.Original;
//Create dataset
DataSet myDataSet = new DataSet("myDataSet");
DataTable people = myDataSet.Tables.Add("People");
//Edit dataset
adapter.Fill(myDataSet, "People");
people.Rows[0].SetField("name", "New Name!");
adapter.Update(people);
//Display the table contents in the form datagridview
this.dataGridView1.DataSource=people;
}
}

The form displays like so:
Looking at the table via Visual Studio's Server Explorer however, doesn't show any change to the table.

3,651,737 | 1 | null | null | 32 | 12,602 | I'm working on some `SocketChannel`-to-`SocketChannel` code which will do best with a direct byte buffer--long lived and large (tens to hundreds of megabytes per connection.) While hashing out the exact loop structure with `FileChannel`s, I ran some micro-benchmarks on `ByteBuffer.allocate()` vs. `ByteBuffer.allocateDirect()` performance.
There was a surprise in the results that I can't really explain. In the below graph, there is a very pronounced cliff at the 256KB and 512KB for the `ByteBuffer.allocate()` transfer implementation--the performance drops by ~50%! There also seem sto be a smaller performance cliff for the `ByteBuffer.allocateDirect()`. (The %-gain series helps to visualize these changes.)

3,652,128 | 1 | 3,654,480 | null | 1 | 1,735 | I've just downloaded the dynamic object framework [Clay](http://clay.codeplex.com/) and am running into issues regarding [castle project](http://www.castleproject.org/container/index.html) versions. Clay uses functionality from v2.0 of "castle" whilst I have a project which has been started referencing v2.5. Needless to say just to make matters more interesting I'm a complete beginner in all things "Castle" and IoC.
The real problem is that upgrading the references within clay solution results in a depreciated method warning. Regardless of whether you supress the method or not, the provided unit tests fail with a "Cannot perform runtime binding on a null reference" exception in the following code in "Intercept" of "InterfaceProxyBehavior":
```
var invoker = BindInvoker(invocation);
invoker(invocation);
```
The code that produces the run-time warning is in "CreateInstance" of "DefaultClayActivator":
```
//var proxyType = _builder.CreateClassProxy(baseType, options);
var proxyType = _builder.CreateClassProxyType(baseType, null, options);
```
As previously stated I'm still a complete beginner with Castle Windsor and just starting out with IoC so haven't even come across the Proxy stuff yet. Frustratingly I have no idea what the error message is even telling me, or asking for.
Have anyone already ported Clay across to version 2.5 of the castle project, so know the steps needed. Or can any one with experience of this part of castle throw anymore light on the error and what I may need to do to resolve it.
I'm still not really any the wiser as to the functionality that is failing, but have had chance to revisit the code running it both with v2.0 (works) and v2.5 (breaks) in castle.core. Attached are two images of the debug information when it works and then when it breaks. The test that it fails on is below, I've indicated the call with a comment.
```
namespace ClaySharp.Tests {
[TestFixture]
public class BinderFallbackTests {
...
[Test]
public void TestInvokePaths() {
var dynamically = ClayActivator.CreateInstance<Alpha>(new IClayBehavior[] {
new InterfaceProxyBehavior(),
new AlphaBehavior()
});
Alpha statically = dynamically;
IAlpha interfacially = dynamically;
Assert.That(dynamically.Hello(), Is.EqualTo("World-"));
Assert.That(statically.Hello(), Is.EqualTo("World-"));
Assert.That(interfacially.Hello(), Is.EqualTo("World-")); // <- Fails on this call
Assert.That(dynamically.Foo(), Is.EqualTo("Bar-"));
Assert.That(interfacially.Foo(), Is.EqualTo("Bar-"));
Assert.Throws<RuntimeBinderException>(() => dynamically.MissingNotHandled());
}
...
}
}
```
This is the debug information when using v2.5 of castle.core and the exception is thrown:
This is the debug information using v2.0 of castle.core (which works) for the same call / line that causes the problem with v2.5

The "po" command doesn't even know about "self":
The problem appears specifically for methods in the `MGMinimap` class. Nowhere else. I can debug from A and see `self` and the others, and then as soon as A steps into `MGMinimap`, the variables pane goes blank like the above image, and gdb doesn't work at all.
The temporary solution to this problem is to create a new class in XCode called e.g. `MGMinimapNew`, copy-paste everything from the real class's .h and .m into the new class, renaming the old class files to e.g. `MGMinimapOld.m|h`, then renaming the new class to `MGMinimap.m|h`. Doing this, things start working again. Still looking for a answer though.

Analysis of Zend_Log reveals following Class Diagram

1. Zend_Log_Filter_Interface relates with Zend_Log_Filter_Suppress, Zend_Log_Filter_Message & Zend_Log_Filter_Priority as depicted, is this correctly laid out in Class Diagram?
2. Is it okay to say that, the Zend_Log contains reference to array of Zend_Log_Filter_Interface and this is composition relationship (similarly for Zend_Log_Writer_Abstract)?
3. As it is obvious that Zend_Log_Filter_Interface is contained by both Zend_Log & Zend_Log_Writer_Abstract, while Zend_Log contains Zend_Log_Writer_Abstract, that makes Zend_Log_Filter referenced by both container (Zend_Log) and contained (Zend_Log_Writer_Abstract); is that some "Design Pattern", if yes what is the name?

Specifically, when I set my `<welcome-file>` to `index.jsp`, the CSS is being loaded and my images are being displayed. However, if I set my `<welcome-file>` to `HomeServlet` which forwards control to `index.jsp`, the CSS is not being applied and my images are not being displayed.
My CSS file is in `web/styles/default.css`.
My images are in `web/images/`.
I'm linking to my CSS like so:

I'm displaying my images as follows:
```
<img src="images/image1.png" alt="Image1" />
```
How is this problem caused and how can I solve it?
---
: I've added the structure of the application, as well as some other information that might help.
The `header.jsp` file is the file that contains the link tag for the CSS. The `HomeServlet` is set as my `welcome-file` in `web.xml`:
```
<welcome-file-list>
<welcome-file>HomeServlet</welcome-file>
</welcome-file-list>
```
The servlet is declared and mapped as followes in the `web.xml`:
```
<servlet>
<servlet-name>HomeServlet</servlet-name>
<servlet-class>com.brianblog.frontend.HomeServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HomeServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
```
---
: I found the problem finally - my servlet was mapped incorrectly. Apparently when setting a Servlet as your `<welcome-file>` it can't have a URL pattern of `/`, which I find sort of weird, because wouldn't that stand for the root directory of the site?
The new mapping is as follows:
```
<servlet-mapping>
<servlet-name>HomeServlet</servlet-name>
<url-pattern>/HomeServlet</url-pattern>
</servlet-mapping>

Here is part of my code ,and you can download the whole code, if you help me correct my code, you can email me.

3,655,979 | 1 | 3,656,819 | null | 0 | 909 | I've got a little objective-c utility program that renders a convex hull. (This is to troubleshoot a bug in another program that calculates the convex hull in preparation for spatial statistical analysis). I'm trying to render a set of triangles, each with an outward-pointing vector. I can get the triangles without problems, but the vectors are driving me crazy.
I'd like the vectors to be simple cylinders. The problem is that I can't just declare coordinates for where the top and bottom of the cylinders belong in 3D (e.g., like I can for the triangles). I have to make them and then rotate and translate them from their default position along the z-axis. I've read a ton about Euler angles, and angle-axis rotations, and quaternions, most of which is relevant, but not directed at what I need: most people have a set of objects and then need to rotate the object in response to some input. I need to place the object correctly in the 3D "scene".
I'm using the [Cocoa3DTutorial](http://c3dt.sourceforge.net/) classes to help me out, and they work great as far as I can tell, but the rotation bit is killing me.
Here is my current effort. It gives me cylinders that are located correctly, but all point along the z-axis (as in this image:. We are looking in the -z direction. The triangle poking out behind is not part of the hull; for testing/debugging. The orthogonal cylinders are coordinate axes, more or less, and the spheres are to make sure the axes are located correctly, since I have to use rotation to place those cylinders correctly. And BTW, when I use that algorithm, the out-vectors fail as well, although in a different way, coming out normal to the planes, but all pointing in +z instead of some in -z)
```
// Make the out-pointing vector
C3DTCylinder *outVectTube;
C3DTEntity *outVectEntity;
Point3DFloat *sideCtr = [thisSide centerOfMass];
outVectTube = [C3DTCylinder cylinderWithBase: tubeRadius top: tubeRadius height: tubeRadius*10 slices: 16 stacks: 16];
outVectEntity = [C3DTEntity entityWithStyle:triColor
geometry:outVectTube];
Point3DFloat *outVect = [[thisSide inVect] opposite];
Point3DFloat *unitZ = [Point3DFloat pointWithX:0 Y:0 Z:1.0f];
Point3DFloat *rotAxis = [outVect crossWith:unitZ];
double rotAngle = [outVect angleWith:unitZ];
[outVectEntity setRotationX: rotAxis.x
Y: rotAxis.y
Z: rotAxis.z
W: rotAngle];
[outVectEntity setTranslationX:sideCtr.x - ctrX
Y:sideCtr.y - ctrY
Z:sideCtr.z - ctrZ];
[aScene addChild:outVectEntity];
```
```
if (_hasTransform) {
glPushMatrix();
// Translation
if ((_translation.x != 0.0) || (_translation.y != 0.0) || (_translation.z != 0.0)) {
glTranslatef(_translation.x, _translation.y, _translation.z);
}
// Scaling
if ((_scaling.x != 1.0) || (_scaling.y != 1.0) || (_scaling.z != 1.0)) {
glScalef(_scaling.x, _scaling.y, _scaling.z);
}
// Rotation
glTranslatef(-_rotationCenter.x, -_rotationCenter.y, -_rotationCenter.z);
if (_rotation.w != 0.0) {
glRotatef(_rotation.w, _rotation.x, _rotation.y, _rotation.z);
} else {
if (_rotation.x != 0.0)
glRotatef(_rotation.x, 1.0f, 0.0f, 0.0f);
if (_rotation.y != 0.0)
glRotatef(_rotation.y, 0.0f, 1.0f, 0.0f);
if (_rotation.z != 0.0)
glRotatef(_rotation.z, 0.0f, 0.0f, 1.0f);
}
glTranslatef(_rotationCenter.x, _rotationCenter.y, _rotationCenter.z);
}
```
I added the bit in the above code that uses a single rotation around an axis (the "if (_rotation.w != 0.0)" bit), rather than a set of three rotations. My code is likely the problem, but I can't see how.

I don't think it should, and there is explicit JCheckBoxMenuItem for that.
Does anyone know why a check box appears in a JMenuItem and how do I disable / remove it?

```

setIcon(icon);

where `getMenu()` returns a `JPopupMenu`.

I've fixed it. The problem is on [Jide](http://www.jidesoft.com) library. I've used it
for a custom LAF of TabbedPanel. And it LAF for popup menus
too as long as it's load.
So the solution is too set it to load menu styles.
```

3,657,122 | 1 | null | null | 16 | 39,434 | I'm trying to create a layout with a 'header' area which contains a logo and some links, and then a content area which needs to extend to the bottom of the page. This is where I'm getting stuck.
I've surrounded the header and content with a container div which has a height of 100%, this works fine. But I can't then get the content div to stretch to the bottom of the container div as giving it a minimum height of 100% appears to take the height from the page body, so I end up with a scroll bar due to the space taken up at the top of the page by the header.
Here's a wireframe which hopefully makes what I'm trying to achieve a bit clearer...
Here is a quick CSS example, this works, apart from there always being a scrollbar at which appears to be the height of the header area...
```
html, body {
height: 100%;
margin: 0;
padding: 0;

}
body {

3,657,128 | 1 | null | null | 0 | 1,301 | Problem with `<div>` tags
Works fine:
Text "Whatever" is in column 1, followd by a radiobutton:
Works also fine (no radio button with text):
The next cell AFTER the text "Whatever" should be displayed in column 1 of the next row - instead directly under the text.
Background:
The table structure is made by my html helper. He generates asp.net MVC2 code to display radio buttons with images(!) in a table structure.
The html helper takes some values like: Generate a table with five radio buttons in two columns and add one radio button with the text "Whatever". (Of course takes the html helper some additional values, but thats not the problem ...)
The table is made with `<div>` tags (no `<table>` tag at all!).
I use the styles "width: 50%;" for a table with two columns and the "float: left;".
Everything works great - until the radio button with the text (and without any image) should be displayed in the last column. See for example picture 2: The after the "text radio button" following radio button (with 3 images) should be displayed in the first column and NOT under the text.
What do I wrong?
Additional info: Same behaviour in IE and firefox.
Thanks in advance!

Getting strange (at 1st look):
But explainable: Think about a chain: Pull the cell / radio button with the 5 images "two positions/columns to the right" (where it should be) and imagine that all following cells/radio buttons would follow. Then everything would be at the right place. ;-)

3,658,373 | 1 | null | null | 0 | 347 | We use in our application cells in a grouped tableview as buttons. Therefore we set a backgroundimage to look the cells like buttons. We used the following code:
```
cell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"bg_gradient_mainmenu_2.png"]];
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.highlightedTextColor = [UIColor whiteColor];
```
which looks like this
The weird thing now is that it works for just some devices with different OS Systems. It definitly doesn't work on new iPhones 4.
Does anyone has a clue how solve that problem?

Id there an option I need to turn on/off to use the normal Session Variables ?

3,659,141 | 1 | 3,659,224 | null | 1 | 323 | I am rotating an image around it center point but need to track a location on the image as it rotates.
Given:
1. Origin at 0,0
2. Image width and height of 100, 100
3. Rotation point at C(50,50)
4. Angle of "a" (say 90 degrees in this example)
5. Point P starts at (25,25) and after the rotation it is at Pnew(75,25)
I haven't touched trig in 20 years but guessing the formula is simple...
