I believe dropping JBoss EL into the app should work. Let us know!
I have tried that.
I am deploying an ear file with jboss-el in the war's lib.
And it did not work. However I am thinking perhaps the jboss-el jar should be in the ear rather than in the war. I tried building trunk now but it is not compiling right now. I shall try later again and post back the result with the jboss-el jar in the ear.
