[kepler-dev] Adding actors programmatically ......

[jagan]

Hi Chad,

I am able to add actor programmitically but I can able to see on the canvas.

I have followed the following steps in adding actors,

============================================
      GriddlesExec wss = null;         
     _actorNameStr = actorName.getExpression();
     container = new EntityLibrary();
     wss = new GriddlesExec(container, _actorNameStr);                   
        -> creates dynamic actor                  
     File kswFile = new File("kar/actors/"+_actorNameStr+".kar");         
     KSWBuilder ksw = new KSWBuilder(wss , false , kswFile);             
-> created kar archive file

     
processKSW(kswFile);                                                                     
-> processed to insert object in cache and build tree with refresh method
  
     System.out.println("Printing Component 
Items");                                 -> printed output to see 
whether entries exist in lib
     LibraryIndex index = LibraryIndex.getInstance();
     for ( Iterator iter = index.items(); iter.hasNext(); )
       {
       LibraryIndexComponentItem key = (LibraryIndexComponentItem) 
iter.next();
       System.out.println( key );
       }
      System.out.println("Printing Ontologies");
      for ( Iterator iter = index.ontologies(); iter.hasNext(); )
       {
       LibraryIndexOntologyItem key = (LibraryIndexOntologyItem) 
iter.next();
       System.out.println( key );
       }
==================================================================
The following code is very similar to your code in CreateKSWDialog.java 
file with minor changes
--------------------------------------------------------------------------------------------------
  private void processKSW(File kswFile)
  {
    try
    {
      KeplerLSID[] actorLSIDs;
      CacheManager cache = CacheManager.getInstance();
      KARCacheObject kco = new KARCacheObject(kswFile);
      
//cache.insertObject(kco);                                                             
-> I have commented out because previous step did this activity
      try
      {
      actorLSIDs = kco.getActors();
      }
      catch(LSIDException lside)
      {
        System.out.println("Error getting actor lsid: " + 
lside.getMessage());
        return;
      }
     
      if(actorLSIDs != null)
      {
        System.out.println("processing kar file: " + 
kswFile.getAbsolutePath());
        //AnnotationEngine AEngine = AnnotationEngine.instance();
        for(int j=0; j<actorLSIDs.length; j++)
        {            
        ActorCacheObject aco = 
(ActorCacheObject)cache.getObject(actorLSIDs[j]);                   
        ActorMetadata am = aco.getMetadata();         
        try
         { //build an entity for each actor in the ksw and add it to the 
actorLibrary
         System.out.println("processing " + am.getLSID());

         LibraryIndexItem subtree = 
LibraryIndex.getInstance().findItem(new 
KeplerLSID("urn:lsid:localhost:onto:1:1#PreConfiguredGridletActor"));
         System.out.println("subtreeitem="+subtree);
           
         LibraryIndex.getInstance().add(new 
LibraryIndexComponentItem(am.getName(), am.getLSID()), subtree);
         LibraryIndex.getInstance().refresh();
         System.out.println("actor " + " loaded into the library in 
category " + subtree.getName() + " with id " +am.getId());
           
         //  NamedObj actorEntity = 
am.getActorAsNamedObj(container);                                                         
-> I have commented out this because
         //  util.EmptyChangeRequest request = new 
util.EmptyChangeRequest(actorEntity, "request change");     ->  I am 
getting duplication error
          //  actorEntity.requestChange(request);
          }
          catch(Exception e)
          {
            e.printStackTrace();
            System.out.println("Error creating ComponentEntity from 
actor " + "metadata: " + e.getMessage());
            return;
          }
        }
      }
    }
    catch(CacheException ce)
    {
      System.out.println("Error with the cache: " + ce.getMessage());
      return;
    }
  }

I have used your class for KSWBuilder except minor change to reflect 
name of the xml file to be name of newly created actor name.

The output statements are as follows:

======================================================================
I have serailized the library index and I saw entries relating to the 
newly added actors.

I have also seen building the tree with new entries in it.

I am not able to see the newly added actors on the canvas. I have even 
tried by reastart Kepler but no luck.

I have seen a file  ( ~/Documents and 
Settings/jagan/.kepler/actorLibrary)  which was created at the time of 
starting (ant run).
I am not able to see newly added actors in this file even after adding 
actors programmatically.

Could you mind to tell me whether I am missing anything?

I am here with enclosing kar file generated at runtime for the newly 
created actor.

I haven't put these things in cvs repository as I have changed few of 
original files that may cause problems to other people.

Once I test my additions, I will put back in cvs repository.


with regards,

Jagan Kommineni
