Getting j_username, and j_password after /j_security_check action

[Seji Thomas]

I would like to know how j_username, and j_password from the form-login-page can be made available to a Struts Action class for supplying them to create a UserCredential object? I use this object to verify and set session context for navigating to my application.

I have searched help for this, and came to know that one can use pre-login or post-login filters to set them in session variable. But unfortunately Tomcat is'nt supporting/recommending using filters. What can be the solution for this? Eagerly waiting for some one replying... and thanxs in advance...
