Do's and dont's with EJB

[Mark Uppeteer]

Since I'm new to ejb, I could use all the hints I can get. I'm busy reading ejb design patters as a start, but I can still use all the hints you can give me. Might be usefull for everyone to share his experience (good or bad)
I'll try to give it a start:
So you should:
- Put session or message beans as entry point of entity beans
but you probably shouldn't:
-Call statefull session beans from stateless session beans (no point at all to that since you lose the state anyway)

Bitter EJB by Bruce Tate is by far the best consolidation of EJB antipatterns.

Few chapters from Bitter EJB

Unless you are quire sure of your competency, I would not prescribe developing EJBs using patterns as a starter reference.
Its useful to consider the patterns down the line in your development experience. I would prefer refering to books like Ed Roman's, and Bitter EJB and go for the initial development efforts.
Its just my personal opinion.

Yes, but knowing what you should not do in advance is better than facing the consequences afterwards isn't it ?

Absolutely. It's much better to read a map and go directly to your destination than to wander around blindly simply trying to avoid areas with signs that say "danger here"....
