Question 1:
It is a CMP Entity bean therefore the ejbPostCreate() is before "Insert data in database", then the answer could be C
Question 2:
I agree with A
Question 3:
Of all ways it must set customer in acount, since he is not null in acount
Then the answers are B and D
Question 4:
Dependent value classes are custom serializable objects that can be used as persistence field.
Then the answers could be A and B

The answer to question 6 has to be B and C. Because all documentation says the setRollbackOnly() can only be called on CMT.
Although not required, application beans should explicitly make the decision
to cause a rollback and not leave it to the container. They can do this by
calling the EJBContext.setRollbackOnly method. Remember, application
exceptions result in a commit unless you explicitly call the setRollbackOnly
method.
Note that setRollbackOnly is only available for container-managed
transactions; bean-managed transactions must use the rollback method of
the UserTransaction object.



UserTransaction also has setRollbackOnly() method
UserTransaction ut = mySessionCtx.getUserTransaction();
ut.setRollbackOnly();
So the answers are B and D

Hi,
I'm in doubt about this question:
9. When setting up the JMS server, in a test environment which is already running message-driven beans (MDB), which of the following properties MUST be configured to correctly communicate messages to a new MDB?
A. Queue JNDI name
B. Initial state to: Started
C. Queue name
D. Connection factory JNDI name
E. Listener port name
Select 2 answers.
Answer A is obviously wrong, E seems to be wrong too, because you set up the listener port in the DD, not in the test environment.
But, you should specify both names and jndi names for both queue and connection factory. So, A, C and D are all correct
Could you show me my mistake?

In JMS Server Properties we have only:
Name, Description, Number of Threads, Queue names, Host, Port and Initial State.
So my answer is B and C
