org.jboss.jms.server.endpoint.ServerSessionEndpoint
The server side representation of a JMS session. A user must not invoke methods of a session concurrently on different threads, however there are situations where multiple threads may access this object concurrently, for instance: - A session can be closed when it's connection is closed by the user which might be called on a different thread. - A session can be closed when the server determines the connection is dead. If the session represents a connection consumer's session then the connection consumer will farm off messages to different sessions obtained from a pool, these may then cancel/ack etc on different threads, but the acks/cancels/etc will end up back here on the connection consumer session instance. @author Ovidiu Feodorov @author Tim Fox @author Clebert Suconic @version $Revision: 2507 $ $Id: ServerSessionEndpoint.java 2507 2007-02-28 23:46:51Z timfox $
