To configure an ActiveMQ JMS client in Spring it is just a simple matter of configuring an instance of ActiveMQConnectionFactory within a standard Spring XML configuration file like any other bean. There are several examples and test cases available and this one shows how to construct an ActiveMQConnectionFactory in Spring which is then passed into a Spring JmsTemplate for use by some POJOs.
e.g. the following fragment of XML shows us creating a JMS connection factory for ActiveMQ connecting to a remote broker on a specific host name and port.

<bean id="jmsFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL">
<value>tcp://localhost:61616</value>
</property>
</bean>

The following shows how to use Zeroconf to discover the available brokers to connect to.

<bean id="jmsFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL">
<value>zeroconf://_activemq.broker.development.</value>
</property>
</bean>

From 1.1 of ActiveMQ onwards you can also use JNDI to configure ActiveMQ within Spring. This example shows how to configure Spring using ActiveMQ's JNDI Support.

If you are using the new XML Schema-based configuration of Spring 2.0 you can embed the ActiveMQ broker XML inside any regular Spring.xml file without requiring the above factory bean. e.g. here is an example of a regular Spring XML file in Spring 2.0 which also configures a broker.

If you are not using a JCA container to manage your JMS connections, we recommend you use our pooling JMS connection provider, (org.apache.activemq.pool.PooledConnectionFactory) from the activemq-pool library, which will pool the JMS resources to work efficiently with Spring's JmsTemplate or with EJBs.
e.g.

<!-- a pooling based JMS provider -->
<bean id="jmsFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">
<property name="connectionFactory">
<bean class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL">
<value>tcp://localhost:61616</value>
</property>
</bean>
</property>
</bean>
<!-- Spring JMS Template -->
<bean id="myJmsTemplate" class="org.springframework.jms.core.JmsTemplate">
<property name="connectionFactory">
<ref local="jmsFactory"/>
</property>
</bean>
