Subject ActiveMQ AJAX Problems
Date Tue, 20 Apr 2010 14:13:32 GMT

Hello. I'm trying to get ActiveMQ AJAX to work but can't so far.

I'm using fiddler, and when I post to our address of
"http://wamqdev1:10201/demo/amq" with request body of
"destination=topic://t1&message=message&type=send" I get a response with the
exception below. The topic I'm posting to does exist.  The AJAX portfolio
example also does work.  The exception and my WEB.xml is below.

Anyone have any ideas? 

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
<title>Error 500 A destination must be specified.</title>
</head>
<body><h2>HTTP ERROR: 500</h2><pre>A destination must be specified.</pre>
<p>RequestURI=/demo/amq</p><h3>Caused
by:</h3><pre>java.lang.UnsupportedOperationException: A destination must be
specified.
