AServerSession object is an application server object that is used by a server to associate a thread with a JMS session (optional).
AServerSession implements two methods:
getSession - returns theServerSession's JMS session.start - starts the execution of theServerSession thread and results in the execution of the JMS session'srun method.AConnectionConsumer implemented by a JMS provider uses aServerSession to process one or more messages that have arrived. It does this by getting aServerSession from theConnectionConsumer'sServerSessionPool; getting theServerSession's JMS session; loading it with the messages; and then starting theServerSession.
In most cases theServerSession will register some object it provides as theServerSession's thread run object. TheServerSession'sstart method will call the thread'sstart method, which will start the new thread, and from it, call therun method of theServerSession's run object. This object will do some housekeeping and then call theSession'srun method. Whenrun returns, theServerSession's run object can return theServerSession to theServerSessionPool, and the cycle starts again.
Note that the JMS API does not architect how theConnectionConsumer loads theSession with messages. Since both theConnectionConsumer andSession are implemented by the same JMS provider, they can accomplish the load using a private mechanism.
