Calling asynchronous services from bpel scripts

[fairfaxroad]

Hi, we're trying to use Switchyard to call an external asynchronous web service (i.e a one-way service call with a matching callback) using ws-addressing to pass the return callback endpoint but we're hitting problems.  What we're finding is that the ReplyTo ws-addressing header we're sending does not have a return Address field populated properly, it comes through as the None URI:

<ReplyTo xmlns="http://www.w3.org/2005/08/addressing"><Address>http://www.w3.org/2005/08/addressing/none</Address></ReplyTo>

We’re struggling to see how to configure Switchyard to populate this with a valid callback endpoint that will trigger the callback receive activity in the BPEL script.  There doesn't seem to be any examples of calling async services from a BPEL script within Switchyard so I was wondering

1. whether this is supported?
2. Does anyone have any advice as to what needs to be configured to set up the callback endpoint and populate the ws-addressing header.

Thanks

Hi Chris

Sorry I don't think this is supported at the moment. When the BPEL engine was integrated into Switchyard, WS-Addressing wasn't supported ([SWITCHYARD-1056] Support WS-Addressing to enable EPR to be specified with invocation - JBoss Issue Tracker) and although it is now supported, the work to provide the address from the BPEL process instance hasn't been done.

Could you raise a jira attaching a simple reproducer, so that we can hopefully get this working soon.

Regards

Thanks for that Gary.  I'll raise a Jira ticket for that but I'm not too sure how useful a reproducible example I can provide as the async services we're attaching to are all internal.  I'll try and find a suitable public one to use.

As a matter of interest any idea on the size of the problem?  This is a show stopper for us at the moment so is it something we could try and fix (probably with a few more pointers) and push the change back up?

Sorry for the delay, we raised this as issue [SWITCHYARD-2480] BPEL: Support calling asynchronous services from a single process by utilising the WS-Addressing - JBo…
