So I am trying to set up a sample showing ActiveMQ’s messaging capabilities.
In particular when I saw the Ajax listener I got excited because this is
exactly what I needed.
Anyway I set up a VERY simple example using the samples on the WIKI and I am
having issues. What am I possibly missing?
I have a simple HTML page that accepts a text and then sends it to ActiveMQ
and I have a listener waiting to alert me when it comes in.
I have ActiveMQ embedded in my test, and looking at the JMX Console I see
the listener getting registered and I see the message(s) getting loaded into
my topic. The wiring doesn’t look like it should be difficult, but for some
reason I get no message :,(
This doesn’t look like it should be so difficult … can anyone give me some
advise?
I am using Tomcat 5.5.27 for my environment and Java 1.6.0_14.
web.xml:

Javascript:

alert("Receiving Message: " + msg);
var mr = new MessageRecord({time:new Date().toString(),msg:msg});
incommingMessages.insert(0,mr);
}
};
amq.addListener("88", 'topic://test.route', ActiveMQHandler.receive);
...
handler: function(button, event) {
var m = sendTab.findById("messageToSend").getValue()
amq.sendMessage("topic://test.route", m);
var mr = new MessageRecord({time:new Date().toString(),msg:m});
}
