All, I switched from using my sender page to using the console Send To capability. What I have discovered is that in all cases of sending from the admin page, both the Msgs Sent and Msgs Received counters increment. However, the receiver only generates output when I send well formed XML through the admin console send page. That leads me to my next two questions; 1) is it required that all messages through ActiveMQ be well formed XML? and 2) can I always expect the variable passed to the handler function to be a JavaScript object (i.e. containing XML)? Pardon me if this is an obvious question, I am new at working with message brokers, especially at this level.

Now, I've got a barebones sender and receiver pair, based on the example in the link below. I see the topic get created when I refresh the receiver, and it has a single consumer, as expected. When I run the sender to send to that topic, I am having issues trying to issue output to the web page on the receiver from within the message handler. I originally tried the example using the alert box. The only time I managed to get an alert to work was when I had an error in the JavaScript contained in the handler. Is there anything special I need to do to output from the handler? I've tried direct document.writes, alert with simple text, even jQuery output (both with and without the .ready function. Any suggestions?

Therefore, you should all jms related stuff inside your web application. Take a look at webapps/demo/WEB-INF/web.xml for an example of how to do it.
