Subject Re: Possible Bug in AJAX/MessageListenerServlet.java?

Yes, it looks like this can be an acceptable workaround until amq.js is
fixed.  The trick is to use something like ExtJS' Ext.Loader.loadScript()
function to bring in a second or third or fourth copy of amq.js, then
encapsulate it in a function.  Here's what's working for me:

function startAMQ () {
	Ext.Loader.loadScript({
		url:
'https://spire.spirebps.com:4444/SpireDev/SpireRoot/Shared/amq/js/amq_jquery_adapter.js',
		scope: this,                   // scope of callbacks
		onLoad: function() {           // callback fn when script is loaded
			Ext.Loader.loadScript({
				url:
'https://spire.spirebps.com:4444/SpireDev/SpireRoot/Shared/amq/js/amq.js',
				scope: this,                   // scope of callbacks
				onLoad: function() {           // callback fn when script is loaded
					// AMQ : Initialize AMQ connection
						var amq = this.org.activemq.Amq;

						try {
							amq.init({
								uri: 'https://spire.spirebps.com:8162/demo/amq',
								logging: true,
								timeout: 20,
								clientId: (new Date()).getTime().toString()
							});
						} catch (e) {
							alert("AMQ initialization error: " + e);
						}

					amq.addListener('testconnection2', 'topic://MyApp/Simulator',
myHandler.rcvMessage);
				},
				onError: function() {          // callback fn if load fails 
					alert("Error while loading amq.js for AMQ2");
				} 
			});
		},
		onError: function() {          // callback fn if load fails 
			alert("Error while loading amq_jquery_adapter for AMQ2");
		} 
	});
};

startAMQ1();


Hope this helps others faced with the same problem.

Bill
