Utility method to create new JmsSession from a given JmsConnection

Parameters:

jmsConnection - the connection from where create a new JmsSession

ackMode - the InternalAckMode to use

isTopic - Indicates if the destination is whether a topic or a queue

jmsSessionManager - JmsSessionManager to retrieve information about the current transaction status

Returns:

a new JmsSession from the given JmsConnection

Throws:
