thanks for answering my question Jari.
I'm not an expert in Java and JSP, so I have more questions.
Session beans should be kept thread safe because a user can open multiple
browser session. Is the 'synchronized (this)' approach the only solution ? And
the situation of using frames with several requests participating the same
session objects. Here also 'synchronized(this) ?
Thanks in advance (also to Craig)
