Hi,
Note: The message that you have got from me below was before you mentioned
the formBean idea. I haven�t tested that one yet.
Basically below you will see a config based on an example that I downloaded
from the net. All that I have done for testing purposes so far is to get my
data from my session bean using the "LoginAction.java". On successful login
the Welcome.jsp is displayed which is where I put the tags that you
suggested.
bye Michael
