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