Class org.apache.activemq.ActiveMQConnection

Examples of org.apache.activemq.ActiveMQConnection.createSession()

org.apache.activemq.ActiveMQConnection.createSession()
Creates a Session object. @param transacted indicates whether the session is transacted @param acknowledgeMode indicates whether the consumer or the client willacknowledge any messages it receives; ignored if the session is transacted. Legal values are Session.AUTO_ACKNOWLEDGE, Session.CLIENT_ACKNOWLEDGE, and Session.DUPS_OK_ACKNOWLEDGE. @return a newly created session @throws JMSException if the Connection object fails tocreate a session due to some internal error or lack of support for the specific transaction and acknowledgement mode. @see Session#AUTO_ACKNOWLEDGE @see Session#CLIENT_ACKNOWLEDGE @see Session#DUPS_OK_ACKNOWLEDGE @since 1.1
