[kepler-dev] GriddLeS Actors missing from screen...

[jagan]

Hello Chad,

        I have changed the contents of  
"configs/ptolemy/configs/kepler/ontologies/keplerActorOntology.owl" to 
make all the griddles actors
in a griddles folder  which is under  Actors folders. I have also added 
one subfolder named "gridlets folder" to the "griddles" folder to store
actors when created by  JGridletActor at runtime. I have updated the 
contents in cvs repository.

        With the previous version (before kar), I was able to create and 
see the dynamically created actors. I have used the following 
methodology to create actors dynamically,

=============================================================================================================
      GriddlesExec wss = null;         
      KeplerLocalLSIDService service = KeplerLocalLSIDService.instance();
      AnnotationEngine engine = 
AnnotationEngine.instance();                     
      _actorNameStr = actorName.getExpression();
            
      wss = new GriddlesExec(new EntityLibrary(), 
_actorNameStr);            
   
    
      String 
keyLSID="urn:lsid:localhost:"+_actorNameStr+":LOCALID0";       
      Iterator lsidIter = service.getLSIDFor(wss);
      boolean isUpdated=false;
      while (lsidIter.hasNext()) {
    String nextLSID = (String) lsidIter.next();
        if(keyLSID.equals(nextLSID)) {
      service.updateLSID(nextLSID, wss);
      engine.addActorAnnotation(nextLSID, "PreConfiguredGridletActor");
      System.out.println("UPDATE: " + nextLSID);
          isUpdated=true;
          break;
          }
    }
      if(!(isUpdated)) {
        String newLSID = 
service.createLocallyUniqueLSID(_actorNameStr);          
        service.assignLSID(newLSID, wss);
    engine.addActorAnnotation(newLSID, "PreConfiguredGridletActor");
    System.out.println("NEW: " + newLSID);       
        }
      service.commitChanges();
===================================================================================================  
 
The full code is available in cvs repository at 
"$KEPLER/src/org/monash/griddles/JGridletCreater.java"
--------------------------------------------------------------------------------------------------------
I am getting a null pointer exeception. Could you mind to advise me 
whether I can able to use this approach for creating actors dynamically.
This step is very crucial for GriddLeS actors to work with in Kepler 
environment. Any sugestions please.

==================================================================================================
