Integration

I envision a following scenario:
A BPEL process hosted on a BPEL Engine running on any BPEL compliant appserver (Oracle or BEA Appserver for instance). The BPEL process will use WSIF/EJB binding to invoke the ejb from the BPEL process or perhaps the BPEL code will use JNDI look-up from the BPEL process to communicate with EJB. Please note that the EJB accesses EIS tier via JCA and provides a stateless API for other clients to communicate.

The various tiers...
BPEL process -> EJB -> JCA -> EIS Tier -> Database

What is recommended practise. to go with JNDI or to use the WSIF/EJB binding? I saw some links posted in the forums (blogs on using WSIF/EJB).

What are good starting points to get this integration step started?

Do you have running samples that show BPEL process invoking a EJB? Is there a technical whitepaper that specifically focus on the scenario I am choosing.

I found a few samples in the bpel/samples directory, but there wasn't any documentation for the EJBBinding It would be very nice if there was a sample that took me from the step where I had a working EJB, and now I want to access it in a BPEL process flow.
