Current version of the project, you mean?  JBoss itself has more current versions, up to v. 7.

I suggest you change this in the present.  It will save your bosses time and money, as has already been mentioned upthread.  Bear in mind that Java EE 5 is already over five years old, and 1.4 came out in 2003.  The differences are significant.  You will really, really want to push back on this.

This is the standard notation for annotations, part of Java for quite a while now.

You need to upgrade the project.  It will cost your bosses too much to stay with the old way.

But since you mention JBoss, you'd probably best stick with that.

Eclipse will plug into any major app server, bundled or not.  It's in the documentation somewhere.
