ClassCastException using JNDI with scoped Classloading

SourceForge Submitter: rz1911 .
Hello,

I try to access an shared object which is bount to JNDI
from two web applications within separate EARs using
scoped class loading. This results in an
ClassCastExecption. When I try to
access the shared object from another VM everything
works fine. It also works fine if the shared object
classes are placed in the default/lib directory. I think
this is because there is an optimization that no remote
calls are used within the same VM. But this optimization
is only OK for classes loaded from the same class loader.
(The same problem seems to cause ClassCastExeptions
if you call EJBs via remote interfaces from diffent EARs
using scoped class loading)

To reprodurce the failure deploy the attached test files
server.ear and client.ear. Open
http://localhost:8080/server (this creates and binds the
shared object an sets a test value). After that open
http://localhost:8080/client (This causes the
ClassCastException (see below).

Source files are attachted, too.

Thanks, Ralf
