ClassCastException out of JNDI

Question

I have an object I am placing in the JNDI tree through a WebLogic
startup class. I then have other classes that access that object. Right
now I am doing testing and I want to get at that object through a
servlet. The problem is that I get a ClassCastException when retrieving
the object. Why? Different classloaders. My object in the JNDI was
loaded with :
weblogic.boot.ServerClassLoader@b62b1638
My servlet was loaded with
weblogic.utils.classloaders.RecursiveReloadOnModifyClassLoader$Slave@1f031637
How can I get to my object. My object is already in the WebLogic
classpath. Is there some way to specify the classloader?
Thanks for any help.

Any ideas what would be causing this problem?Here are some more details. I get the exception when I call:
KodoHelper.getPersistenceManagerFactory("java:comp/env/jdo/Kodo", new
InitialContext());
But if I call:
Context context = new InitialContext();
pmf = (PersistenceManagerFactory)context.lookup("java:comp/env/jdo/Kodo");
Then it works fine it seems.
