Hi all,
I'm always getting the following exception when using CMP (ejb 1.1 and ejb
2.0) in orion 1.1.36 and earlier versions:
on the client side :
java.lang.InternalError: Object was null but still part of the cache
at com.evermind.server.rmi.bb.invokeMethod(JAX)
at com.evermind.server.rmi.a2.invoke(JAX)
at com.evermind.server.rmi.a3.invoke(JAX)
at __Proxy1.create(Unknown Source)
at om.fnv.kozijncalc.entities.klanten.KlantTest.<init>KlantTest.java:41)
at com.fnv.kozijncalc.entities.klanten.KlantTest.mainKlantTest.java:100)
Below is all the code and the deployment descriptors. I think it has
something todo with orion's memory (bean caching ) managment. Has someone
else have equal problems ? Or is it a bug ? Where can I find the bug list?
Thank in advance.
Wim Veninga.

(I can sent your a .ear with al the code (also with the other beans and
relations between them for how to use ejb 2.0). Just sent me an email and i
will sent the .ear back.
