Dejan according to the latest MEAP of ActiveMQ in Action section 9.4.2 Example 9.25 you should be able to produce messages from Ajax. I'd like to be able to produce a message from javascript in order to verify the system is working appropriately. Then I can work on consuming messages with the Ajax script. I debugged the Ajax script through Firebug to figure out what it was posting to the server. When trying to do the same through Fiddler the broker throws the exception noted in this thread.
If I can't get a simple send to work following the example in ActiveMQ in Action then I can't properly troubleshoot why the consumption of messages through the Ajax API isn't working.
