[esb-issues] [JBoss JIRA] Closed: (JBESB-719) The messages can be lost in case of ESB termination

The messages can be lost in case of ESB termination --------------------------------------------------- Key: JBESB-719 URL: http://jira.jboss.com/jira/browse/JBESB-719 Project: JBoss ESB Issue Type: Bug Security Level: Public(Everyone can see) Components: Rosetta Affects Versions: 4.2 Milestone Release 3 Reporter: Jiri Pechanec Assigned To: Daniel Bevenius Fix For: 4.2.1 CP1 Even if the ESB is using internally reliable JMS as a transport the messages can be lost during ESB termination. The reasons for this behaviour are two 1) ESB uses internally queue sessions with AUTO_ACK flag 2) Pick-up and deliver couriers works in different session Proposed solution 1) Change flag to CLIENT_ACK 2) JMS sessions are allocated from the pool using JMSConnectionPool.getQueueSession(). If the allocated session is stored into ThreadLocal variable and returned by the subsequent calls by the same thread and get commited on call JMSConnectionPool.closeSession() then all internal message transfers via JMS will be done in transaction - one transfer/one transaction.
