j_security_check is not usable by anything but the container.
thanks for following up. I don't really get the message, though. Yes, j_security_check is a special alias used by the system. Using it from HTML forms is common practice. So what's wrong with redirecting from a JSP?
Its not usable unless the container is the one using the form.
I 'm also encountering the same problem. Could you please expound a bit more on your post? I'm actually just a beginner and I couldn't make heads or tails of it. :)
