You have a multithreaded application that looks up the WebLoqic JMS ConnectionFactory object from the JNDI tree. Which statement is correct in this scenario? (Choose the best answer.) 

Answer options:

A. It is not permitted. A multithreaded application cannot access the ConnectionFactory object.
B. The access to ConnectionFactory object MUST be synchronized.
C. The ConnectionFactory object can be referenced in a multithreaded application without any special considerations.
D. Multiple threads trying to use the ConnectionFactory object simultaneously will throw an exception.
E. In a multithreaded scenario, connection objects cannot be safely created from the ConnectionFactory.

B

A connection factory supports concurrent use, enabling multiple threads to access the object simultaneously. A session and its message producers and consumers can only be accessed by one thread at a time (i.e. the access must be synchronized). Their behavior is undefined if multiple threads access them simultaneously. Incorrect Answers: A, E: A connection factory supports concurrent use, enabling multiple threads to access the object simultaneously. C, D: A session and its message producers and consumers can only be accessed by one thread at a time. Their behavior is undefined if multiple threads access them simultaneously.
