[kepler-dev] Adding new actor

hi there,
Is the following the correct way of adding new actor to the library panel:
1) create actor folder under src/actors
2) add manifest & xml files with appropriate ids.

I am able to create one actor from above method...  however for another 
actor its not able to find the actor on classpath:

     [java] The class name you entered was not found in the classpath.  
Note tha
t the class you are trying to enter must be in the classpath from which 
you launched this program: null
     [java] java.lang.NullPointerException: Could not clone actor 
'PegasusJobAbstract' from the 'util.PegasusJobAbstract' class, the actor 
null, meaning it was
not found? Perhaps there is a classpath problem of the karlib needs to 
be flushed?
.....

The actor's class is in build/classes , which is on the classpath. I 
have tried adding after re-building kar and deleting .kepler..however 
its still not able to find the actor on the classpath.
If i instantiate the above actor from the workspace...and try to add it 
to the library by "importing kar archive"..it gives me similar errors of 
not finding classpath.
 If anybody knows what I might be doing wrong, please let me know :)

thanks!
nandita.
