 Posted: Tue May 04, 2004 9:01 am Post subject: return value of an EJB bean |
 |
|
Hi,
I am not sure this is tha right place, but it seems okey.
I am develping EJB Beans running in JBoss and developing them in jbuilderX.
I am having trouble with the return values of the function in the EJB beans.
For example, I have an EJB called PETalker and it has a function,
MyDoucumentClass getDocument(String id);
When I called this function from a remote interface I got an exception. I am
sure this is
related with the return value of the functionm but I could not solve it. If
I replace MyDocumentClass
type with String for example, no exception occurs.

If you posted the exact exception it would be easier to answer...
OTOH, I can guess, if String works, and MyDocumentClass does not. You
forgot that any class that is returned from an EJB method has to be
Serializable. So make your MyDocumentClass implement Serializable, and
the problem should go away.
Also, the borland.public.jbuilder.enterprise group would have been a
more appropriate place for this question. Anything about EJB's should
go in there.
