Hi,
this days i started my preparation (theoretical) for passing from an application developer to a web developer (I'm moving to London and it seems most of the java job offers are in this field).
supposing that obviously one can't acquire real skill with some books and exams, i find useful and interesting to start the preparation with books ands exams, and i'd want to know if some can give me an opinion on the study of EJBs.
why is it stuck to version 1.3? is the technology stuck, or surpassed (at least in the way it is treated)?
it's worth the resources spent, generally speaking? otherwise i'll focus on something else.

thanks!

The differences between 1.3 and 1.4 where EJB are concerned were not large enough to warrant a new exam.
5.0 is so new a new exam (if any) isn't ready yet.

Exams themselves (especially multiple choice tests) aren't a good investment in themselves.
They are however a good incentive to keep focussed on learning, to have a target to work towards.

Even though J2EE 1.3 is somewhat "old" (and this is debatable), it is the most widely deployed technology in the server-side Java world. In light of this, it definitely makes plain sense for people to get certified for EJB 2.x as their expertise will be needed at some point when all those systems will gradually need to be migrated to EJB 3.0 or some other equivalent technology.

To sum up, while it is pointless to get certified in a technology that is not yet mainstream and that has not yet acquired wide industry acceptance, it is definitely paramount that people continue to learn current technologies, i.e. the ones that are in widepread use TODAY, so that they can best serve the industry and corporations when the latter need to get forward and upgrade their system to the newer versions.

Studying ejb 2.X will probably give you a better understanding of what was going on before 3.0, which is quite important considering that there are so many projects using them.
