Episode I is the perfect description of the series. Absolutely no thoughtful plot... just a bunch of "gee-whiz" special effects. I'd rather go see "Lord of the Rings" again.

We tried it at our work, and it didn't work, but not because of the EJBs but because of Reporting, and finding good people.
I agreee wholeheartedly. We had the same problem here 6 months ago. Inexperienced EJB programmers with large over head on the EJB side. Took awhile to narrow it all down but it was more due to the fact that they programmers didn't know how to implement the Entity Bean model properly.
The one thing to understand though is that the inherit reflection needed doe the app server to do all that code for you (in the case of CMP) will add overhead no matter how good the yours or the app servers JDBC code is.
We did a lot of testing to prove this and now what we 'usually' do is use the "fast lane reader" pattern to get lists and info that is read only by using JDBC directly to the database. When we need the transactions, security and isolation of the container (and don't want to write our own custom model), we use the CMP/BMP model for Entity Beans.
This has been successfull performance wise for a large ERP application running the EJB 1.1 specs and I suspect it gets even better when you move into EJB 2.0.
You'll see that it is a very fine balance of 'when to use what' to get the best performance for the least headaches on your system.

I'm using A Programmer's Guide to Java Certification. It, like any good certification book, will walk you through each section that is covered by the exam
