public class JmsTemplate
extends JmsDestinationAccessor
implements JmsOperations

Helper class that simplifies synchronous JMS access code.

If you want to use dynamic destination creation, you must specify the type of JMS destination to create, using the "pubSubDomain" property. For other operations, this is not necessary, in contrast to when working with JmsTemplate102. Point-to-Point (Queues) is the default domain.

Default settings for JMS Sessions are "not transacted" and "auto-acknowledge". As defined by the J2EE specification, the transaction and acknowledgement parameters are ignored when a JMS Session is created inside an active transaction, no matter if a JTA transaction or a Spring-managed transaction. To configure them for native JMS usage, specify appropriate values for the "sessionTransacted" and "sessionAcknowledgeMode" bean properties.

This template uses a DynamicDestinationResolver and a SimpleMessageConverter as default strategies for resolving a destination name or converting a message, respectively. These defaults can be overridden through the "destinationResolver" and "messageConverter" bean properties.

NOTE: The ConnectionFactory used with this template should return pooled Connections (or a single shared Connection) as well as pooled Sessions and MessageProducers. Otherwise, performance of ad-hoc JMS operations is going to suffer. The simplest option is to use the Spring-provided SingleConnectionFactory as a decorator for your target ConnectionFactory, reusing a single JMS Connection in a thread-safe fashion; this is often good enough for the purpose of sending messages via this template. In a J2EE environment, make sure that the ConnectionFactory is obtained from the application's environment naming context via JNDI; application servers typically expose pooled, transaction-aware factories there.

execute

public <T> T execute(SessionCallback<T> action)
          throws JmsException

Description copied from interface: JmsOperations

Execute the action specified by the given action object within a JMS Session.

When used with a 1.0.2 provider, you may need to downcast to the appropriate domain implementation, either QueueSession or TopicSession in the action objects doInJms callback method.

Specified by:

execute in interface JmsOperations

Parameters:

action - callback object that exposes the session

Returns:

the result object from working with the session

Throws:

JmsException - if there is any problem

execute

public <T> T execute(SessionCallback<T> action,
            boolean startConnection)
