Ok,
I've implemented annotatin support for tomcat with a small test in ejb3 module under:
org/jboss/ejb3/test/dd/web/servlet/EJBServlet.java
I haven't tested any XML stuff beyond basic EJB-refs. This means the injeciton-target, etc... I'll get to that on Monday.
JSP injeciton is not supported yet. The hooks aren't in the current Tomcat codebase, but are easy enough to add. The problem is that the java compiler for JSPs does not insert annotaiton information. I'll start a new thread for this.
