Hi again,

well, the lookup seems to be ok now (code snippet below). But then following exception occours:

Code:

try {

  Object objRef = initialContext.lookup(jndiName);

   if (java.rmi.Remote.class.isAssignableFrom(narrowTo))

      return javax.rmi.PortableRemoteObject.narrow(objRef, narrowTo);  // line where exception occurs...of course ;-)

   else

      return objRef;

} finally {

   initialContext.close();

}

Any idea?

Cheers

Hi all,

just to close this one, have change the ContextLoaderLister to the LocalHome-Interface cause Remote-Interface isn't necessary.

But even with the Remote-Interface, the point is:

Just use the right JNDI-Name for the Interface.

Old JNDI-Name used for

remote: SecuritiesOB

local: SecuritiesOBLocal

but should be now for example

remote: java:app/myapp-ejb-4.3.0-SNAPSHOT/SecuritiesOB!com.customer.myapp.authob.interfaces.SecuritiesOBHome

local: java:app/myapp-ejb-4.3.0-SNAPSHOT/SecuritiesOB!com.customer.myapp.authob.interfaces.SecuritiesOBLocalHome

Bloody hell of ancient EJB stuff.

A real pain in the a... to migrate from 4.0.5.GA

Cheers

Carsten
