> Define the following connection factory for the JMS sender (note the cache
> level parameter):
> <parameter name="default">
> <parameter
> name="java.naming.factory.initial">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
> <parameter
> name="java.naming.provider.url">tcp://localhost:61616</parameter>
> <parameter
> name="transport.jms.ConnectionFactoryJNDIName">QueueConnectionFactory</parameter>
> <parameter name="transport.jms.CacheLevel">producer</parameter>
> </parameter>
> Now try to send a message to the EPR
> "jms:/SimpleStockQuoteService?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://localhost:61616&transport.jms.DestinationType=queue"
