Hi,
I am getting a rather nasty ClassCastException when i try and remove a
many-to-many join (implemented like the MovieDatabase example). My question
is how do i go about debugging this? Is it possible to get access to the
generated .java files?
Thanks in advance for any advice
stack traces
.

: ClassCastException with struts
Greetings,
I've been trying Orion and I'm having some problems using multiple
applications (or copy's from the same application).
What I have is one application, used (and modified) by some guys.
So, each one has his own web-app and application and a source
area for struts
Having struts locally on each webapp, strutsjar in WEB-INF/lib/
and struts-config in WEB-INF/, allows to run just one application
without errors (ClassCastException)
This happens because all struts-config are the same, just running
under different copies of the application
The problem seems to be with struts, that always throws a
ClassCastException when the second application trys to run
Without using Struts, everything seems to work fine and each
application runs separatly I think that Struts uses some 'common
area configuration' that can only be created and used by one
.
But this object is loaded in the servlet using a ClassLoader that is
different from the default ClassLoader of the servlet.
The result is a ClassCastException when doing a narrow using this object and
the class as loaded by the default ClassLoader. The narrow works fine when
the object's ClassLoader is used

I can establish the correct Initial Context and locate the required object.

Since I saw a question regarding junit and classcastexceptions on this list
(before I subscribed to it) just one pointer for everyone:
Using stock junit for EJB calls you will run into classcastexceptions
because of the custom class loader junit is using. I already asked the junit
guys to put
Worked like a charm; I am much obliged.

I have generally found that a ClassCastException (usually nested
three-layers deep in ominous sounding Orion exceptions) usually
indicates a wrong bean (or class) specified in the deployment
descriptor.
For instance, I was tearing my hair out over a ClassCastException I was
getting every time I
