Rather allot needs to be writtenby those that understand the intents of the JS API

AjxDispatcher

appears to be a way for anyone to register a global function that can then be run 'by name'

ie.

../ZmCalendarApp.js:   AjxDispatcher.registerMethod("GetCalController", "CalendarCore", new AjxCallback(this, this.getCalController));
Tasks_all.js:           var cc = AjxDispatcher.run("GetCalController");

AjxCallback

AjxRpc or howto access a JSP

MainHelloView.prototype._updateHTML_JSP = 
function(to, body) {
	var url = this.helloWorldZimlet.getResource('hello_world.jsp');

	to = AjxStringUtil.urlEncode(to);
	body = AjxStringUtil.urlEncode(body);
	var reqParam = 'to=' + to + '&body=' + body;
	var reqHeader = {"Content-Type":"application/x-www-form-urlencoded"};

	AjxRpc.invoke(reqParam, url, reqHeader, new AjxCallback(this, this._updateHTMLCallback));
};
MainHelloView.prototype._updateHTMLCallback=
function(result) {
	var r = result.text;
	DBG.println(AjxDebug.DBG2, "result:" + r);
	this.getHtmlElement().innerHTML = r;
};
