Use getters/setters only

I seem to remember somewhere reading that one should use getters and setters only when accessing persistent fields. This seems obvious from outside the entity class, but not so obvious from inside. Can anyone point me to the manual or other resource that describes this or explain it here? Thanks.

Strange behavior with a distributed transaction

Hi, I have a scenario where I'm trying to run a distributed transaction across two websphere 6.1 app servers on two different nodes (2 physical machines). A stateless session bean on server 1 makes an entry to a table in the database after which it calls the remote ejb on server 2 which again

Re: Strange behavior with a distributed transaction

Thanks Michael. However, I forgot to mention this: I also tried swapping the two find calls i.e do a find for the entity persisted on the remote server first and then try and do a find for the entity on the local server. This time it hangs on the first call itself i.e the output now is: On
