Hi,
You have an extra "}" after the _feed function
I also did the following in case the above doesn't fix it:
change your script includes to:
<script type="text/javascript" src="amq/prototype.js"></script>
<script type="text/javascript" src="amq/behaviour.js"></script>
<script type="text/javascript" src="amq/_amq.js"></script>
- or just -
<script type="text/javascript" src="amq/amq.js"></script>
These jars are served from activemq-web.jar so you don't have to copy
all the js files
If it still doesn't work, please also send your web.xml.
Regards,
Patrick

I am trying to familiarise myself with
org.apache.activemq.web.MessageListenerServlet to publish and subscribe to
ActiveMQ topics.
The servlet is working and logging so I can monitor it. I have a simple
publisher that appears to be able to post to a specified topic but my simple
subscriber just never seems to receive anything. Help appreciated big time.
