I have thought about this a bit lately and I never came up with a good solution. In this case, you are sort of hacking the framework by using our view library to render the UI, but the processing happens elsewhere. That's why I don't know if there is a good solution to sprinkle in some validation as well, since validation is handled as a function of the processing.
I have thought about trying to put an action out in front of j_security_check. I am not sure if it would work, but you can try to create a thin action that has the getters/setters for j_username / j_password, then dispatch to j_security_check. I don't know if you're feeling up to it, but if you hack around enough and find a way to pre-process the form with struts then hand it off to j_security_check, I'd be interested in how you did it. -Wes On Wed, Jun 17, 2009 at 11:06 AM, Daniil Petrov<petro...@gmail.com> wrote: > Hi, > > I am using JAAS authentication in a Struts 2 web application.
