J2EE Exam for interview

[John Fontana]

Hi gang,
I've been called to take a J2EE exam for a Web Developer position. While JSP/Servlets are old news to me, I'm very much a novice when it comes to EJB's, which I was told weighed heavily on the exam score. I can whip up and deploy a mean stateless session bean pretty quickly, but that's where it stops.
If anyone has taken a test like this, or has any good resources for cramming, or other advice (giving up is not an option!), please let me know.

I think this will help.

I like this attitude! Do your best, but don't panic. Then
You are always a winner.

Thanks! This looks like a great tutorial...right now I'm trying to get an IDE/Container combination working so I can debug and learn more quickly (So far the best setup I've found is JDeveloper because of the embedded OC4J Server)...

Thank you, and I love your site! Especially the scenario of the programmer who worked with servlets before they were invented...I was recently turned down for an interview because they required that I worked with Swing components before they were invented...

I attended IBM developer's conference about 2 years ago, they had a lot of very interesting, as well as advanced topics on EJBs and overall architecture of Java-running web sites. Try ibm.com , you'd have to dig around to find where their learning center is.

Actually, a good start is here:

One project I had was using WebSphere 2.5 (2.x or something, it was a while back), JSP, Servlets, etc. People keep asking me why we didn't use EJBs on it. Java Beans haven't been invented yet!

Great link -- I look forward to learning EJB, but at the same time I wonder if EJB's aren't overkill. It will take some time working with it before I stop thinking that they are just a way for IT companies to squeeze a million dollars out of companies when all they need is a decent Perl message board!

Sometimes the most important thing to learn about a technology is not how to make it work, but why it exists. EJB (or more to the point, all of J2EE) isn't a tool to achieve simplicity, if you think of simplicity as meaning the smallest amount of code. It is a tool to achieve separation of concerns, and hence divisibility of the work.
Divisibility doesn't matter for small one-man projects. It is very useful for multi-person projects. Divide-and-conquer strategies make each piece simpler; the whole, when assembled, may be more complex than you'd expect from other kinds of technologies... but for multi-person projects you may not have been able to keep the piece work organized enough to end up with a working whole.
