NullPointerException which generating the WSDL file using ws

[tapeshag]

Hello,
I am trying to generate the descriptiors using the wstools. When I try to run it with my config file, I get the following error

---------------------------------------------------------
Exception in thread "main" java.lang.NullPointerException
at org.jboss.ws.tools.JavaToWSDL.generate(JavaToWSDL.java:303)
at org.jboss.ws.tools.helpers.ToolsHelper.handleJavaToWSDLGeneration(ToolsHelper.java:122)
at org.jboss.ws.tools.WSTools.process(WSTools.java:132)
at org.jboss.ws.tools.WSTools.generate(WSTools.java:120)
at org.jboss.ws.tools.WSTools.main(WSTools.java:61)
---------------------------------------------------------------

I am using wstools which gets shipped default with JBOSS-4.0.4GA release.

Attaching the contents of the interface and config files

wstools-config.xml
=============

<java-wsdl>

<namespaces target-namespace="http://hello.ws.jboss.org/"
type-namespace="http://hello.ws.jboss.org/types"/>

<webservices servlet-link="TrivialEndPointJSE"/>
</java-wsdl>


TrivialServiceInterface.java
====================
import java.rmi.Remote;
import java.rmi.RemoteException;

public interface TrivialServiceInterface extends Remote
{
String purchase (String person) throws RemoteException;
}

I found the reason behind the Exception.
I was not defining the interface in any package. Looks like it is required. So I added

package org.myapp;

and it started working.
is it a bug in wstools?

I like to correct one of my old comments.

"I was not defining the package in my interface"
I wrote it other way round.

Thomas: Pls update this line in the bug description as well
