| |
| <p>A <em>very</em> common gotcha when working with JMS is forgetting to start the JMS connection, creating a consumer and not having it receive any messages. I myself have tripped up over this one many many times! <emoticon ac:name="smile"></emoticon></p> |
| |
| <p>To try and help diagnose this mistake and give you an early warning by default ActiveMQ 4.2 detects this and generates a handy warning message telling you to call the <a shape="rect" href="http://java.sun.com/j2ee/1.4/docs/api/javax/jms/Connection.html#start()">Connection.start() method</a> on the JMS connection.</p> |
