WebStart and EJB: NoClassDefFoundError: javax/ejb/NoSuchEJBException

Question

Hi.
I've created a small EJB project and a client which is called via webstart. If I test it with eclipse or with a standalone client all works as expected. But if I open the client with webstart every lookup to the EJB classes fail.
Error Message:

  <resources>
    <j2se version="1.4+" />
    <jar href="lib/commons-logging-1.0.4.jar" />
    <jar href="lib/j2ee.jar" />
    <jar href="lib/openejb-client-3.0.jar" />
  </resources>The lookup code is (shortened):
Properties prop = new Properties();
prop.put( Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.RemoteInitialContextFactory" );
prop.put( "java.naming.provider.url", "ejbd://[host]:4201" );
Context context = new InitialContext( prop );
Object implClass = context.lookup( "VobServiceRemote" ); // Exception is thrownAny ideas what could be wrong?
thanks,
Stefan
@edit: I'm using Apache Geronimo as application server.

If someone run into similar problems: include openejb-client.jar and geronimo-ejb_.3.0_spec_1.0.1.jar into the jar file of the web start client (I used FatJar for building) instead of just referencing to them. After this it will work as expected.
