There are two almost similar versions of jboss-spring deployer. One with old InvocationContext, @EJB and the other one with fixed (see http://jboss.org/jbossBlog/blog/bburke/2006/06/02/JBoss_EJB_3_0_Preview_R...). Check what version 4.0.4.GA has - see jboss-ejb3x.jar in ejb3.deployer. This is not the cause - look before this. I tried to rectify this. Put the right order in application.xml. Or adjust deployer order. No reaseon. I use a lot of JSTL in our portal app with no problem. Sorry, but yuck. Still very unflexible. I like wiring a lot of small beans. And this doesn't do that.
