I was just able to configure Jboss and JAAS successfully. When I visit a authentication-required page it automatically asks for my userid and password. I fill in the userid and password and I'm now able to access the restricted pages.
However when I go back to the same page, it asks again for the userid and password. I'm just a newbie and I'm not sure how to bypass the reauthentication.
Thanks.
PS. I'm pasting my web.xml config just in case
 <security-constraint>
 <web-resource-collection>
 <web-resource-name>Secure Content</web-resource-name>
 <url-pattern>/pages/secured/*</url-pattern>
 </web-resource-collection>
 <auth-constraint>
 <role-name>*</role-name>
 </auth-constraint>
 </security-constraint>
 <login-config>
 <auth-method>FORM</auth-method>
 <form-login-config>
 <form-login-page>/pages/test2.jsp</form-login-page>
 <form-error-page>/logoff.do</form-error-page>
 </form-login-config>
 </login-config>
