I've been fighting with this issue for 3 days and I guess StackOverflow is my last resort. I ran out of ideas why it doesn't work :( I'm using GWT 2.4.0 and JDK 1.6.
I was going through this tutorial and got stuck with crashing GWT app. The app crashes if I mention com.google.web.bindery.requestfactory.shared.RequestContext interface in my client code. I'm not even using it. I just have unused method that takes RequestContext as parameter. I tried referencing RequestFactory - same exception. So I suspect I'm missing something related to RequestFactory package. I added -logLevel DEBUG to GWT compiler and here is what I have:
DEBUG: Rebinding com.vsezavtra.courierApp.client.ManagerShell.ManagerShellUiBinder.
DEBUG: Checking rule <generate-with class='com.google.web.bindery.requestfactory.gwt.rebind.RequestFactoryGenerator'/>.

Full log is here. My application is very small. Here is my GWT XML file
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.0//EN" "http://google-web-toolkit.googlecode.com/svn/releases/2.0/distro-source/core/src/gwt-module.dtd">

<entry-point class='com.vsezavtra.courierApp.client.courierApp'/>
</module>
Main entry-point class:
package com.vsezavtra.courierApp.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootLayoutPanel;
public class courierApp implements EntryPoint
{
public void onModuleLoad()
{
RootLayoutPanel.get().add(new ManagerShell());
}
}
Bindable UI class
package com.vsezavtra.courierApp.client;
import com.google.gwt.core.client.GWT;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.Widget;

public class ManagerShell extends Composite
{
interface ManagerShellUiBinder extends UiBinder<Widget, ManagerShell>
{
}
private static ManagerShellUiBinder uiBinder = GWT.create(ManagerShellUiBinder.class);
public ManagerShell()
{
initWidget(uiBinder.createAndBindUi(this));
}
// if I remove this method everything works :(
public void SetTest(RequestContext test) {}
}
and corresponding XML file
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui'>
<g:VerticalPanel>
<g:HTMLPanel>
Test!
</g:HTMLPanel>
<g:HTMLPanel>
Test2!
</g:HTMLPanel>
</g:VerticalPanel>
</ui:UiBinder>
and finally my web.xml file has only root "web-app" element because I have no server-side part (yet).
I'm using IntelliJ IDEA 10.5.2 to debug the app.
Please let me know if you have any additional question. I really don't know what else I can do :(
It appears you are missing a javax.validation implementation that RequestFactory is dependent on:
ERROR: Line 81: ConstraintViolation cannot be resolved to a type.
In the tutorial for RequestFactory in the Wiring section hibernate-validator is recommended as well as several other dependencies:
* requestfactory-server.jar * javax/validation/validator-api-1.0.0.GA.jar * A JSR 303 Validator of your choice, such as hibernate-validator
