REST webservice + HTML using jquery libs is not working when deployed on same web application

Hello,
I have made some changes in my example to make it more simple for demo on javaranch.
Please find the screenshot of project structure in Eclipse.

Please Note:- As mentioned in my original post - I have replaced the jquery .js files with my test.js. As I found, the issue is not specific to jquery, even it is not working with any included .js file

Here is my code snippet.

HelloWsService.java

Test.js

web.xml

cvr_test.html

index.html

With above code, when I run
1. http://localhost:8080/CVR_WS_GitHub/cvrrest - I get 'Hello sayDefault' on my web page. As it points to the mapped webservices
2. http://localhost:8080/CVR_WS_GitHub/cvrtest - I do not get anything in my UI, but getting following error in server and firebug console

a. server console error.

b. firebug error

The very interesting point here is,
If I remove the webservice class i.e. HelloWsService.java and make my application a pure WebApplication and restart tomcat server.
Then I am successfully able to run http://localhost:8080/CVR_WS_GitHub/cvrtest
and I get alert message along with 'Hello CVR TEST HTML' in UI.

I really do not understand the root cause of this issue.

Please help me. Also let me know, if I am doing something wrong.
Hope, I have posted all the required details.

Thanks in Advance.

Components made with basic HTML tags are not working correctly with Struts 2

Hello Joe,
Thanks for directing me to the right link/location.
I View the html source in browser and as per the source.. UI is generated.
My learning is - All basic HTML elements are placed together and then all Struts specific elements are presented in <table> which is created dynamically by struts API internally.
to get rid of this - I myself created table inside <form> and put all Struts + HTML tags under different <td> and it works correctly.
In this scenario, as the <table> is already in place, struts is not adding any new <table> dynamically. So every thing is inplace correctly.

Now my work is to have DDCL plugin correctly inplace with my other UI components.

Thanks.
Below is the new UI with all elements ordered correctly

Components made with basic HTML tags are not working correctly with Struts 2

Hello Ulf,
As mentioned in my initial thread, my aim is to use Juery DDCL plugin to create DropdownCheckboxList. but I was facing the issue.
so I thought to add some UI components using raw html tag and then I will write my jquery to do the needful.
But while adding UI component with raw HTML tag, I faced this issue and left with NO CLUE about why this is happening.

hope this clarifies my need.

thanks.

Components made with basic HTML tags are not working correctly with Struts 2

Heading - "Here is the component with basic HTML Tags. This should go below Company Office"
and
Combobox with label Geo Locations is EXPECTED to appear below Company Office dropdown,
but in ACTUAL both the components made with raw HTML tags are appearing on TOP. ie. before all UI components made with struts tag.

How to stop Table Selection on Button Click ?

I have been trying from some time to stop table selection on Button click and made table display grey out .so easily understand that table is in non selection and non editable mode.
But unfortunately after trying hard, I am not getting a way to achieve this.
I need to disable radio button selection when I click on 'Stop Editing' button.
Please help me in on this.

ActionListener on JComboBox fires subsequently on next all Comboxes

Hello,
I am facing a problem with JComboBox ActionListener. I have 3 comboBox and the logic which I am expecting is -
User select Item from 1st combobox, then only 2nd comboBox will be populated.
then user selects 2nd combobox, then 3rd comboBox will gets populated.
...
and so on.

I have made only 3 combobox here for this post. in an actual scenario I have around 8-10 combobox'x each having nearly 10 items.

The problem I am facing here is very tedious. All the listeners in all combobox's fired.
I tried removing and then re-adding action listener, but that gives me compilation issue.
1st issue - Cannot refer to a non-final variable listener inside an inner class defined in a different method
to correct this, if I make ActionListener definition as final, then another compilation issue comes - The local variable listener may not have been initialized.

Please help me in resolving this.

JSeparator expectation with GridbagLayout

Hello,

I am working on Swing Application and trying to use JSeparator to divide the panel Horizontally.
But, unfortunately my Separator is showing as a full line. Instead it is just showing in particular area only.

Can anyone please help me, on how to correct this.

Here is my Sample code

import javax.swing.*;
import java.awt.*;
public class GridBagSeparator{
public static void main(String[] args) {
JFrame frame = new JFrame("Laying Out Components in a Grid");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel(new GridBagLayout());
panel.setBorder(BorderFactory.createLineBorder(Color.BLACK, 5));
GridBagConstraints layoutContraints = new GridBagConstraints();
String artboardText = "artboard";
layoutContraints.gridy = 0;
layoutContraints.gridx = 0;
layoutContraints.weightx = 1.0;
panel.add(new Label("1=="+artboardText), layoutContraints);
layoutContraints.gridy = 0;
layoutContraints.gridx = 1;
panel.add(new Label("2=="+artboardText), layoutContraints);
JSeparator sep = new JSeparator(SwingConstants.HORIZONTAL);
layoutContraints.gridy = 1;
layoutContraints.gridx = 2;
layoutContraints.fill = GridBagConstraints.HORIZONTAL;
panel.add(sep, layoutContraints);
layoutContraints.gridy = 2;
layoutContraints.gridx = 2;
panel.add(new Label("3=="+artboardText), layoutContraints);
frame.add(panel);
