Re: BPEL Implementation: Latest changes mean no need for deploy.xml !!

Sebastien,

Which operating system are you running on?
The new code compiles the BPEL process to the CBP file and then reads it in. The error is with reading in the file.
What I don't see below is an error from the new code saying that it is unable to load the file, which is curious. 


Yours,  Mike.

Luciano,

There is something that you might be able to help me with right away.
I am running into intermittent problems with transactions in the registration of a BPEL process with the ODE server. The transaction causing the problem seems to be the one in the BPELImplementationProvider start() method. 

What is this transaction for?

try {
    txMgr.begin();
odeServer.registerTuscanyRuntimeComponent(implementation.getProcess(), component); 

    odeServer.deploy(new ODEDeployment(deploymentDir), implementation );
    txMgr.commit();
} catch (Exception e) {
    e.printStackTrace();
    txMgr.rollback();
}
Will it cause a problem if I remove this transaction? To me it does not seem to provide any value when the Process is being supplied by Tuscany. I can't see any requirement for it in the ODE documentation. 


Yours,  Mike.
Rebuiling from scratch gives me the error below. Anybody else seeing this? Could it be related to the transaction problem discussed here?
