Mission Accomplished!!!

   Today I've passed "Oracle Certified Professional Java EE Business Component Developer" exam with score 90%. I used the most standard suite of OCPJBCD materials:

• Enterprise JavaBeans™ 3.1 specification - complete data source, you can find everything here
• OCP JavaEE 6 EJB Developer Study Notes by Ivan A Krizsan - outstanding notes, focused on practical part
• Enthuware 1Z0-895 EJB V6 mock tests - very good and I think the cheapest mock exams.

   This should be enough, but you can also read some other books eg. "EJB 3 in Action" or "Enterprise JavaBeans 3.1" and remeber to visit Big Moose Saloon. 

Finally another OCPJBCD question, which I sadly screwed up:

A Singleton bean can expose which of the following client views?

1. An asynchronous message destination
2. Web Service view
3. Message Driven
4. EJB 2.x Remote home
5. EJB 3.x local business
6. JPA Entity view

Do you know? The correct answer is 2,5.
