I have started to modify the itest/bpel/helloworld to first expose the BPEL using webservices binding and then consume it in a J2SE client app. Then I'll look into moving to a webapp scenario. If you have your sample app as a iTest or Sample, maybe you could provide it in a JIRA to speed up on my side...
BTW, I'm at a conference this week, so i won't promise a complete answer before Monday.
