javax.jms Interface ServerSession
public interface ServerSession
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 theServerSession
's JMS session.start
- starts the execution of theServerSession
thread and results in the execution of the JMS session'srun
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.

getSession
Session getSession() throws JMSException
- Return the
ServerSession
'sSession
. This must be aSession
created by the sameConnection
that will be dispatching messages to it. The provider will assign one or more messages to theSession
and then callstart
on theServerSession
. - 返回:
- the server session's session
- 抛出异常:
JMSException
- if the JMS provider fails to get the associated session for thisServerSession
due to some internal error.
start
void start() throws JMSException
- Cause the
Session
'srun
