SCBCD

Did the sun JEE5 certification yesterday.
I started preparing the evening before, which did not leave nearly enough time,
but all was well :)
The exam is not easy, which is a plus for it's credibility, compared to some mock certifications on the market.
The EJB3 course I'm teaching at sun (sl351) is a good start, but not sufficient.
Mikalai Zaikin's SCBCD 5.0 Study Guide was the best resource I found on the web.

Topics I got:

• JNDI, JPQL, transactions, exceptions, rollback
• combining transactions and entitymanager
• orm mapping of an association class
• NO deployment descriptor syntax questions
  
• libraries included in JEE5
  
• mapping users to roles
  
• business method that you can call locally/remotely
• at which level can you apply specific annotations?
• legal return types for @webmethod
• composite primary keys
• mixing EJB2/3
• persistence units
