revisiting ClassCastExceptions

[jay.baker@xxxxxxxxxxxxxx (Jay Baker)]

I did review the recent discussion on the 'dreaded' ClassCastException
and it was helpful. I've crossed my first bridge. Now the second ...

I have an object in the JNDI that implements (my own interface)
IMonitor. It has a method addObject(IMonitoredObjectobj). My
implementation of these two classes are no where near my servlet
classpath, or the java classpath. They are in my weblogic classpath.
Also, there are no other places where these classes might be hiding.

I have a servlet that gets my object out of the JNDI. This works now,
yea! However, I am getting a ClassCastException when trying to call
Monitor.addObject() with a new IMonitoredObject created within my
servlet. I see the following :

error inserting into monitor java.lang.ClassCastException:
jndistuff.Monitored
this object = jndistuff.MakeState
this class loader =
weblogic.utils.classloaders.RecursiveReloadOnModifyClassLoader$Slave
monitor class = ...Monitor
monitor class loader = weblogic.boot.ServerClassLoader
inserted class = jndistuff.Monitored
inserted object class loader = weblogic.boot.ServerClassLoader

Monitor implements IMonitor and jndistuff.Monitored implements
IMonitoredObject.

It seems they have the same ClassLoader and they implement the correct
interfaces. What else am I missing? Thanks for any input.
