[jboss-user] [JBoss Portal] - Re: Cannot retrieve user: Unable to locate current JTA trans

"So in your case I would recommend using a Tomcat Valve to process your authentication and set up the Subjects the way JAAS does it inside Tomcat. "

Is this my ONLY option? I am not familiar with either how Tomcat valves work, or how subjects are set inside Tomcat, so it might be a little painful to get this done in a day or so :( 

"btw- why can't you re-use JBoss Portal's JAAS mechanism and just plug in your own LoginModule for your application specific authentication logic? "

Could you elaborate on this? I've implemented a number of custom login modules that are stacked. I was able to authenticate the users against this security realm SO LONG as I used container managed authentication and j_security_check. Everything worked fine. But, I need to move away from that and explicitly initialize the LoginContext (using the same security realm) due to some other reason and that is where things are not working.
