Hello,
I'm blocked from trying to have fun with Google gadget and GWT. ;-)
I got the exception like below in trying to compile a simple Google
gadget on Eclipse (Galileo).
I highly appreciate if someone can give me the crew of this cause.
Regards.

Here's the Google gadget class (IGadgetExperiment2.java) I try to
compile:
package com.inetools.igadgetexperiment2.client;
import com.google.gwt.event.dom.client.ClickEvent;
import com.google.gwt.event.dom.client.ClickHandler;
import com.google.gwt.gadgets.client.Gadget;
import com.google.gwt.gadgets.client.UserPreferences;
import com.google.gwt.gadgets.client.Gadget.ModulePrefs;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.RootPanel;
@ModulePrefs( title = "iGoogle Gadget Experiement2", author = "Art",
author_email = "[email protected]")
public class IGadgetExperiment2 extends Gadget<UserPreferences> {
@Override
protected void init(UserPreferences preferences) {
Button simpleButton = new Button("SimpleGadget");
simpleButton.addClickHandler(
new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
Window.alert("Hello World!");
}
}
);
RootPanel.get().add(simpleButton);
}
}
And here's the IGadgetExperiment2.gwt.xml file:
<?xml version="1.0" encoding="UTF-8"?>

gwt-gadgets-noredist.jar from
