JBOSS BPEL: invoking web services dinamiclly

javilaalonso Apr 10, 2007 6:03 PM

I have a question.

I don't know how BPEL solves this problem.
Imagine a process with different paths of execution depending on a variable.
Every path invokes a different web service. We can model this behaviour by using the if-else structure.

The problem is where the different paths of execution invoke the same web service, meaning they have the same WSDL document , portype , etc..
but they are deployed in different locations (ex:differente machine).

Is there any other way to model such behaviour with only a path of execuation using a parameter with the address of the service ?

Thank you

Hi again.
I have just found it in the wsbpel-specification-draft.

The notion of < partnerLinks > is used to directly model peer-to-peer conversational partner relationships. < partnerLinks > define the shape of a relationship with a partner by defining the portTypes used in the interactions in both directions. However, the actual partner service may be dynamically determined within the process. WS-BPEL uses a notion of endpoint reference, manifested as a service reference
container <sref:service-ref>, to represent the data required to describe a partner service
endpoint.

I just don't know how to put this into practice.

Thanks,
