Hi dears, I have web application witch uses javax.servlet.Filter implementation class for filtering. In this class I perform a lot of process (security and more) and everything work well on JBoss 3.0.7. I try to migrate on JBoss 4.0.3 and it's very interesting that in my implementation class (the filter) I cannot see request parameters and attributes, just this lists in request object are empty and I have a lot of problem after this fact. There isn't redirecting because the flow of the web application is well, but I can't see the parameters and attributes. Any ideas for this mistical fact?
