ClassCastException using EJB from a service

Question

Hi all,
I developed a DeployService and currently I'm getting a ClassCastException while accessing the a EJB.
I put the lookup within a delegate which is also be used from a webDynpro application. With the WebDynpro App everything work properly, but if I call the delegate from the service a SAPClassCastException I thrown, when I cast the object to the home interface.
The coding is as follows:
               Properties props = new Properties();
               props.put(Context.PROVIDER_URL,"localhost:50004");
               props.put(Context.INITIAL_CONTEXT_FACTORY,
               "com.sap.engine.services.jndi.InitialContextFactoryImpl");
               context = new InitialContext(props);
               Object obj = context.lookup(jndiName);
               EJBHome ejb = EJBHomeFactory.getInstance().lookup(jndiName, ComponentHome.class);
               ComponentHome componentHome = (ComponentHome)ejb;
Thanks a lot for the help.

Hi Falk,
Hey just tell me that what is the EJBHome and ComponentHome and EJBHomeFactory in your coding.....
You can try the following code for the same.
Object obj =(Object) jndicontext.lookup("<Your JNDI name>");
TestEJBHome home = (TestEJBHome) javax.rmi.PortableRemoteObject.narrow(
               obj,
               TestEJBHome.class);
TestEJB hello = home.create();
Here, TestEJBHome is your Home interface of the EJB and TestEJB is your remote interface. Now you can use hello object to call your business methods of EJB.
