The other day I was looking at EJB3 and JBoss 4 to see what has happened since last time. I have developed a number of applications in EJB2 and EJB2.1 and I have, as many else, many times found the EJB-way lengthy and clumsy. As a minimum, you had to add xdoclet to ease the pain. I went off in the JDO direction for a while and liked it very much. Now in EJB3 they have applied annotations in a way similar to xdoclet and JPA persistence has learned from other framworks. Entities are local only, but we only used remote for Session Beans anyway. Pragmatic. Fewer interfaces, dependency injection for resources and elegant use of event handling instead of callbacks. I like it.
