Hi all,
Recently I was going through some mock exam and faced the following question:
----------------------------------------------------
"Consider the following method of a stateless session bean. Which of the given options are correct regarding this method?"


Code :

public xxxx() throws
{
try
{
InitialContext ctx = new InitialContext();
QueueConnectionFactory queueConnectionFactory = (QueueConnectionFactory) ctx.lookup("java:comp/env/jms/myQueueConnectionFactory");
...//other valid code.
}
catch(Exception e)
{
throw new EJBException(e.getMessage());
}
}

Options :

Select 1 correct option.

1. It may be ejbCreate() method.

2. It may be ejbRemove() method.


3. It may be a business method.


4. It may be setSessionContext() method.


5. This code is invalid in any stateless session bean method.
----------------------------------------------------
The correct answer was "3. It may be a business method."
For me it doesn't look rigth. Resource Manager is registered via resource-ref tag, hence it's available in "java:/comp/env" scope. And JNDI access to "java:/comp/env" IS ALLOWED for all methods listed above.
Can somebody clarify this point to me?
Thanks in advance.
Diana

Hi, Diana
In chapter "7.8.2 Operations allowed in the methods of a stateless session bean class" of EJB spec 2.0, it has a clear restriction on which methods could be accessed regarding EJBContext, Transaction, JNDI and resource manager. Comparing with that, the 3rd answer is quite right.
Regards,
