Thanks for replying. Here are the details you requested:
1. Employee class
2. DeploymentDescriptor.xml
To recreate the problem please code a simple server which returns an
Employee containing subordinates (Vector of Employee). This would cause
stack overflow. In my case server side implementation is Weblogic 6.0.
If you would like, I could make a tar/zip ball and send it to you as
attachment.
I can tell you that it is not a case of simple cyclic reference since
subordinates contained
strictly other employees (not self). It definitely is a case of graph (may
contain cycles)-- which you
stated is not handled in Apache Soap 2.2. This could be stated in bean
serializer documentation.

Soumen.

Subject: Re: Bugs in Soap 2.2 BeanSerializer?
The bean serializer is only a convenience serializer intended to
help you out when it does what you are seeking. When it doesn't
do what you want, you have to write a serializer yourself. One
of the bean serializers limitations is that it does not serialize
graphs - i.e., it does not generate id/idref stuff. Not hard to
do, but that's not what the bean serializer do. If you'd like to
do it and contribute the code we'll all be happy.
That said, we will always fix any real bugs. Can you please post
your *bean* data type? What you posted as Employee is not a bean.
Also post your SOAPMappingRegistry lines or the deployment
descriptor (if its on the server side).
I'm curious as to why what you did caused a stack overflow in
any case; so if you can post a full example I'll try to make it
print a better error for that case.
