After some debugging,I found
"com.google.gwt.event.shared.UmbrellaException: One or more exceptions
caught, see full set in UmbrellaException#getCauses' when calling
method: [nsIDOMEventListener::handleEvent]"(in web model) is caused by
runtime null pointer.Question is
why this kind of runtime null pointer exception didn't got thrown out
under host model.Actually,blow code won't thrown out any exception and
even got alert popup in my laptop(gwt 2.4+java 7 64bit+ubuntu 12.04
64bit+eclipse 3.7).Anybody knows how to enforce eclipse throw out
exception whenever a runtime null on JavascriptObject pointer occurs.

public class GWTTest implements EntryPoint
{
public static class JsObj extends JavaScriptObject
{
protected JsObj()
{
}
public final native void setValue(String Value)/*-{
this.Value=Value;
alert(Value);
}-*/;
}
/**
* This is the entry point method.
*/
public void onModuleLoad()
{
JsObj jsObj = null;
jsObj.setValue("val");
}
}
