The error you are getting is due to the fact that you are getting the EJBObject
instead of your home object.
You'll have to cast-narrow it like this.
Object objref = initial.lookup(yourBean);
yourBeanHome home = (yourBeanHome) PortableRemoteObject.narrow(objref,
yourBeanHome.class);

Subject: WebLogic - Almost there
Alright, first and foremost I want to thank all of you who helped me get this far.
We're almost there.
I'm now getting a semi-unusual error. A class cast exception, which tells me that I am
somehow casting incorerectly which strikes me as odd, since this is an example from a
book(Mastering EJB and the J2EE by Ed Roman). Heres the exception and the code.

Any ideas? Once again, thank you for all your help thus far.
