I have there are some issues in Javascript.
I rewrite it as follows. It is working fine in currently Grizzly workspace.
<script type="text/javascript">
dojo.require("dojox.cometd");
function setUp() {
//dojox.cometd.init("cometd");
dojox.cometd.startBatch();
dojox.cometd.init(new String(document.location).replace(/http:\/\/[^\/]*/,'').replace(/\/\/.*$/,'\/cometd')+"cometd");
dojox.cometd.subscribe("/hello/world", "publishHandler");
dojox.cometd.endBatch();
}
function publishHandler(msg) {
alert(msg.data.test);
}
dojo.addOnLoad(setUp);
</script>
