Cannot narrow object??

Question

Hi,
I previously had the following fragment of code inside a servlet (which worked fine):
Context ctx = new InitialContext();
BeanEJB beanEJB = null;
BeanEJBHome beanHome = null;
Object obj = ctx.lookup("ejb/BeanEJB");
beanHome = (BeanEJBHome ) PortableRemoteObject.narrow(obj, BeanEJBHome.class);However, I moved the above code to the run() method of a new thread I created and now the PortableRemoteObject.narrow() call throws a ClassCastException.
Can anyone help?
Thank you!

Do you have A's client jar in B's package? You might need this unless
they are in the same ear. Otherwise it looks like a classloding bug.

Hello,
<br><br>
My application is composed of 2 different package A and B. All deployed in the same server.<br>
- A implements EJBA<br>
- B implements EJBB<br>
EJBA is registred in the JNDI tree as ejb.a<br><br>
When EJBB runs these line of code :<br>
Object obj = context.lookup("ejb.a");<br>
System.out.println("ref:" + obj); // ref : com.coface.util.ejb.tools_<b>cvb9yr</b>_HomeImpl@a64642<br>
AHome home = (AHome) PortableRemoteObject.narrow(obj, AHome.class);<br>
Narrow raises :<br>
java.lang.ClassCastException: Cannot narrow remote object to AHome
at weblogic.iiop.PortableRemoteObjectDelegateImpl.narrow(PortableRemoteObjectDelegateImpl.java:242)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:134)
<br><br><br>
I have no idea what can be wrong and how I can debug this kind of exception.<br>
I just noticed this odd "cvb9yr" in the looked up instance class. Thought I am not sure how this name is generated.<br>
Anyone could help me to track down the cause of this exception?<br><br>
Thanks<br>
