Subject Re: [Spam: 5.0] Durable Subscription and Message Expiration
Date Thu, 08 Mar 2007 09:33:26 GMT

I'm using a topic no doubt about it (furthermore i have more than one
consumer reading the same messages at the same time)

I "browse" the messages using the browseMessages() operation of this topic
in the jconsole under :
org.apache.activemq/localhost/Topic/myTopic
