Dynamic endpoint resolution in OpenESB

Question

Hi,
I was wondering whether OpenESB also supports dynamic resolution of target endpoints. My impression so far is that I need to explicitly specify all connections from service consumers to service providers in a service assembly's jbi.xml deployment descriptor using the CASA editor in NetBeans. However, one of the strengths of the NMR in my opinion is that it can dynamically resolve endpoints to send message exchanges to. However, this would mean that the SA's jbi.xml must not contain any <connection>s, doesn't it? Does OpenESB's NMR support this at all? I would really like to be able to deploy a service consumer to a service engine without needing to explicitly specify the name of the endpoint providing the consumed service but instead specify the service interface name only letting the NMR resolve this to a matching endpoint at runtime.
Regards,
Kai

Hi Kai,
The BPEL SE supports dynamic endpoints allowing you to programatically (in the flow) change the port name, service name and address info. I've modified my flows to call an internal AddressResolution flow that calls a EJB in the Java EE SE that looks up address info from a DB. It works great but took a while to get rights as the Namespaces have to be perfect when assigning the XML to the Partner Link.
