If I'm not mistaken, this will only work for components that
where the "class" definition is itself a composite actor.
It won't work for actors defined in Java.  The reason for this,
by the way, is security... We don't want it to be possible to
create models that stealthily load and execute Java code from 
some server...  The current scheme is weakly secure in that
Ptolemy/Kepler only ever executes Java code that has been installed
on the local machine...
