+The messagin examples require that JMS connection factories and 
+destination resources be created before deploying and running
+the samples. 
+
+More specifically, you must create a javax.jms.TopicConnectionFactory
+resource with an JNDI name jms/TopicConnectionFactory, and a 
+javax.jms.Topic destination resource with JNDI name jms/Topic. In 
+Sun RI/Glassfish, the destination resource must have an additional
+property that links it with a physical destination. To provide that, 
+add the property "name" with value "Topic" to that resource in the admin 
+GUI.
