GWT and Struts

[Surya Kant]

Hi All,
Currently i have struts application which is up and running.Now i need to provide some more functionalities to my project.So I decided to code using GWT.Now i have finished my GWT coding and want to integrate with struts application.
Has anyone tried this option before?
If yes please let me know the steps to follow.

I would not recommend trying to integrate GWT with a Struts project. GWT requires its own style of programming that doesn't match well at all with a Struts project. There are other ways of integrating AJAX into a Struts project such as the DOJO toolkit that are much easier to integrate with Struts.

I was planning on using GWT with Struts 2. There are two main features which I require.
1. The forms might have components which require AJAX (Auto complete feature)
2. Upon submitting the form, the values of the components need to be displayed in the URL. This is a requirement because, the resutls page needs to be bookmarkable.
PS: The submit could be a Struts form submit action.

For this, I thought that the solution could be to have a GWT form included in a struts jsp page. However, the problem I face is that I am not able to access the values of the GWT components when I submit the form. Any idea, how to solve this problem? For that matter, I do not even have to use Struts; can use some other framework

Thank you,
Kaushik

Hi,
i create a sample application with gwt and struts . I am using cypal studio. When i run my project it is giving the following error "Resource not found: employee.action; (could a file be missing from the public path or a <servlet> tag misconfigured in module com.atc.sample.employee.gwt.xml ?"

My action class

  public class Employee extends ActionSupport{
	public String getString(String user){
		return "server says Hi "+ user;
	}
}  

entry point

 public class employee implements EntryPoint {

	public void onModuleLoad() {
		Button button = new Button("submit");
		button.addClickHandler(new ClickHandler(){
			public void onClick(ClickEvent event) {
				Window.alert("Hi usman");
				LoginAsync instance = (LoginAsync) GWT.create(Login.class);
				ServiceDefTarget target = (ServiceDefTarget) instance;
				target.setServiceEntryPoint( GWT.getModuleBaseURL() + "employee.action" );
				instance.getString("usman", new AsyncCallback(){
					public void onFailure(Throwable caught) {
						Window.alert( "error" );
						
					}
					public void onSuccess(Object arg0) {
						Window.alert( "server Says::" + arg0.toString() );
						
					}
				});
				
			}
		});
		RootPanel.get().add(button);
		
	}   

service classes
