Re: Re: Re: Instantiate process from application

        Hi,

 It seems your code would work only if after line:

     SharkInterfaceWrapper.setProperties("X:\\tws-community-2.2\\conf\\Shark.conf",
true);

 you put the following:

     SharkInterfaceWrapper.getShark();

 Sasa.

     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

                                       [shark] Instantiate process from
             Please respond to         application
               shark@...









 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.
