This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
When you say, its not working, do you see any error messages? I don't have much knowledge about how that tag is supposed to work and this question looks more related to JSP than JBoss. I will move this to the JSP forum where you might get a solution.
Moderators: If later, this turns out to be JBoss specific issue, please feel free to move it back to the JBoss forum.
