Google Web Toolkit: Re: Tracing GWT exceptions

I have tried to write this "subclass RequestFactoryServlet to pass an ExceptionHandler of your own":

package com.mydomain.myproject.server.servlet;

import com.google.web.bindery.requestfactory.server.RequestFactoryServlet;

@SuppressWarnings("serial")

public class RequestFactoryServletMihu extends RequestFactoryServlet

{

RequestFactoryServletMihu()

{

super(new DefaultExceptionHandlerMihu());

}

and:

package com.mydomain.myproject.server.servlet;

import java.util.logging.Logger;

import com.google.web.bindery.requestfactory.server.DefaultExceptionHandler;

import com.google.web.bindery.requestfactory.shared.ServerFailure;

public class DefaultExceptionHandlerMihu extends DefaultExceptionHandler

{

private static final Logger logger = Logger.getLogger(DefaultExceptionHandlerMihu.class.getCanonicalName());

@Override

public ServerFailure createServerFailure(Throwable throwable)

{

logger.finest("DefaultExceptionHandlerMihu: " + throwable.getMessage());

return super.createServerFailure(throwable);

}

and in web.xml I have:

<filter-name>gaeAuthFilter</filter-name>

<filter-class>com.mydomain.myproject.server.servlet.GaeAuthFilter</filter-class>

</filter>

<filter-mapping>

<filter-name>gaeAuthFilter</filter-name>

<servlet-name>requestFactoryServlet</servlet-name>

</filter-mapping>

<servlet-name>requestFactoryServlet</servlet-name>

<servlet-class>com.mydomain.myproject.server.servlet.RequestFactoryServletMihu</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>requestFactoryServlet</servlet-name>

<url-pattern>/gwtRequest</url-pattern>

</servlet-mapping>

and I get an error:
