Title: RE: How does the <env-entry> tags work?

Hi there, sorry for not understanding that you were talking about the descriptors.
Why dont you logon through a sessionbean that handles all the fine-grained security stuff you want it to have?
Normal procedure would be to have a page acting as a logon form, that will then call a session bean with the values you want, say username/password.

Then lets say that sessionBean returns another sessionbean, that can only be created with a ValidUserObject (given by the first sessionBean if authentication was ok).

Now ,the returned sessionbean could hold all the methods you want to enable for valid users..

I cant get my head arround why you do not want to send in the identifying values through a method..

Another way of sending data between the layers would of course be by using JMS messaging.. But how would you make a 'session' out of it?

Hopefully, someone else on this list gets a better grip on what it is that you want to accomplish, as I fear that this is not totaly clear to me.
