Async BPEL process

Hy guys I've got a question for you all,
    I'm writing a silly application made of two BPEL process: the first one, called call, is a sync process that invoke in an async manner the second one, echo, and then reply to the caller.
As you may imagine the echo process nothing do than send back the received string.
here is my problem: invoking call I've got a run-time error : "Unknown operation "echoReq" on port Type "echoOutPortType"!
The think is that I never use echoOutPortType with echoReq operation.
I don't know why I got this.
I forget: I'm using ode1.0.
Here is my bpel and wsdl files and deploy.xml too!
Thank you all, regards

Simone

Re: Async BPEL process

Posted by Simone Maletta <si...@alice.it>.

Hy guys,
    I solved the problem, I discover that to make an async call I need to

Thank you all
