Re: {Spam?} WfActivity and XPDL relation

Frans, an xpdl just is a *description* of a process. Once you instantiate 
a process, the process instance is then in "open" state. After it has been 
started, it is in "open and started" state. So the xpdl itself cannot have 
information about state, since it is not a process instance but just a 
description of a process.

If you have a process instance, in order to find which activities are in a 
certain state, say STATE_OPEN_NOT_RUNNING_NOT_STARTED, you can use 
something like this follwoing code:

        ExecutionAdministration execAdmin = 
Shark.getInstance().getAdminInterface().getExecutionAdministration();

        execAdmin.connect(un, pw, "Shark", null);
 
        try {
                for (int ii=0; ii<assignments.length; ii++) {
 
                        String processKey = 
assignments[ii].activity().container().key();
                         WfProcess sharkProcess = execAdmin.getProcess( 
processKey );
                        System.out.println("assignment " + ii + ": " + 
assignments[ii].activity().key() + ", " + 
assignments[ii].activity().state());
                        WfActivityIterator activityIterator = 
 
sharkProcess.get_activities_in_state(SharkConstants.STATE_OPEN_NOT_RUNNING_NOT_STARTED);
                        WfActivity[] sharkActivities = 
activityIterator.get_next_n_sequence( 0 );
 
                               for (int i = 0; i < sharkActivities.length; 
i++) {
                                        if (sharkActivities[i] != null) {
                                          result.add(sharkActivities[i]);
                                          log.debug("adding: " + 
sharkActivities[i].key() + ", " + sharkActivities[i].state());
                                        }
                                        else log.debug("sharActivities[i] 
for i=" + i + " is null");
                         }
 
                      }
                  }
                  catch(Exception e2) {
                          e2.printStackTrace();
              } finally {
                execAdmin.disconnect();
              }

Look in org.enhydra.shark.api.common.SharkConstants.possibleActivityStates 
to see which activity states are valid.
