Deployment order of BPEL processes

Kurt Stam Master

Is there a way we can control the  order on which BPEL jars are deployed? Typically as services depend on  one another it'd be nice if the deployer can check the children are up.  I'm asking because the UDDI design calls for dynamically pulling in the  wdsl from WS endpoints and some of that happens at deploytime.

    Gary Brown says:

     

    The  services only depend upon the interfaces of the other services, not the  actual implementations.

     

    Don't think we should be expecting all services  to be up and running before an invoking service is deployed - that would  increase the coupling/dependencies between implementations, which is  not a good thing.

     

    What specifically needs to be done at deployment time,  that couldn't wait for the actual lookup to occur prior to invocation?

    The issue i that createPartnerChannel is called during the deployment  of  the bpel.jar. So the wsdl can of the partner channel can only be  read  if it is deployed. This works fine if it is all contained in the  one  bpel.jar, however if the partner service is deployed in another  archive,  then we can have deployment order issues.

    Well it ended up all resolving itself. The 'createPartnerChannel' executes on a background thread, so it simply waits till the server is up.
