You can set values in a form when you come to a page in Struts.

Thanks a lot Adam
for your help!
My solution that I currently have is to
add a paramter withwait to a action, that
should be coupled with a waiting-page.
It works but do be honest I've to ask another person
in the team on monday why it works and the request-parameters will now be
forwarded!
Are you interested in this solution?
How to you know the real target action
in the waiting.jsp?
Thanks for your help I think after a short time I'll understand!
