+ * More than one JMS connection factory could be defined within an Axis2 XML

+ * <p/>
+ * These connection factories are created at the initialization of the
+ * transportReceiver, and any service interested in using any of these could
+ * specify the name of the factory and the destination through Parameters named
+ * JMSConstants.CONFAC_PARAM and JMSConstants.DEST_PARAM as shown below.

+ * <parameter name="transport.jms.ConnectionFactory" locked="true">myQueueConnectionFactory</parameter>
+ * <parameter name="transport.jms.Destination" locked="true">TestQueue</parameter>
+ * <p/>
+ * If a connection factory is defined by a parameter named
+ * JMSConstants.DEFAULT_CONFAC_NAME in the Axis2 XML, services which does not
+ * explicitly specify a connection factory will be defaulted to it - if it is
+ * defined in the Axis2 configuration.

+
+The only change is in the listenOnDestination method in JMSConnectionFactory
+to use Tuscany threads instead of the setMessageListener call approach when
+running in a JEE container where setMessageListener is prohibited. There are
+several classes copied in this Tuscany package as many of the constructors
+and methods are not public so we can't just subclass to fix the problem.
