Re: Instantiate process from application

Hi Luke,

Here's some code sample from our application, which may help you:

ut = SharkInterfaceWrapper.getUserTransaction();
ut.begin();

/*"xpdl" below is a domain object for us which has info about package
defintion, verison etc. and getProcessManager() is * a method I will
reproduce below.
*/
WfProcessMgr processMgr = getProcessManager(sharkConnection, xpdl);

process= processMgr.create_process(null);

/*if you want to set process variables now, then you can do so now as
follows:*/
process.set_process_context(myContextMap);

process.start();
ut.commit();

Here's the getProcessManager method using our xpdl domain object:
private WfProcessMgr getProcessManager(SharkConnection sharkConnection,
                  Xpdl xpdl) throws Exception {
      XPDLBrowser xpdlb = Shark.getInstance().getXPDLBrowser();
      String procDefName =
            xpdlb.getUniqueProcessDefinitionName(
                        sharkConnection.getSessionHandle(),
                        xpdl.getPackageId(),
                        (new Integer(xpdl.getVersion())).toString(),
                        xpdl.getProcessDefinitionId());
      WfProcessMgr mgr = sharkConnection.getProcessMgr(procDefName);
      return mgr;
}

Hope this helps,
regards,
Geeta

We are trying to use the Shark API to instantiate (and interact with) a
process from an external Java application.

We looked in the Shark code (latest from CVS) and found the SharkTest area,
however it appeared to have a lot of extra calls.  Our engine is running
and the process is loaded, so what is the minimum amount of code needed to
obtain a link to the server instance and instantiate it.  Is this already
documented somewhere?  Has anyone done this, and would you be willing to
post a simple example to the list?

Thanks in advance for your help.
