Hi Philippe, Calvin,
thanx for a fast response!

I have written a helper class "HomeInterfaceFactory" that
does the same thing as what you said. This is not the problem.

You are absolutely right. I tried this and it works again.
I also saw this lazy load technique from Richard
Monson-Haefel. I also found in his book, that
this initialization should be done at ejbActivate().
The question is, if I always have to initialize
the local fields in ejbLoad() does it make any sense to
use this lazy load technique? When do I get (subject != null)?
Or how often do I get (subject != null)? I would like to
know how this works in Jonas...
