Hi Mike, Please find the composite file, wsdl file for the bpel and the bpel process file attached her with the mail. I am using a jms message to call my java-sca-service and this in-fact calls my bpel service. That is the flow of call happening in my app. Thanks & Regards Roshan
-----Original Message----- From: Mike Edwards [mailto:[EMAIL PROTECTED] Sent: Monday, October 20, 2008 6:10 PM To: [email protected] Subject: Re: Reference a BPEL service from a Java SCA service Roshan, This error is from deep in the ODE BPEL engine that Tuscany uses to run BPEL processes. It's not an error that I've seen with any of the BPEL applications that I have run. Can you post details of your SCA application please? Like the composite file you are using, the BPEL process script, related WSDL files etc. This may give us some hint as to what is going on. Also - have you run a BPEL process component successfully with your setup (eg one of the Tuscany sample applications)?
