原生ajax request:
//===================Ajax Frame Start======================================
var xmlRequest=null;
//Send Ajax Request
function ajaxRequest(url){
	xmlRequest = null;
	if(window.ActiveXObject){
		xmlRequest = new ActiveXObject("Microsoft.XMLHTTP");
	}else{
		xmlRequest = new XMLHttpRequest();
	}
	//'GET',URL asynchronous
  	xmlRequest.open("GET", url, true);
  	xmlRequest.onreadystatechange=invoke; 
  	xmlRequest.send(null);
}
//Callback Method For Ajax Request
function invoke(){
	if(xmlRequest != null && xmlRequest.readyState == 4) {
		if (xmlRequest.status == 200) {
			parse(xmlRequest);
		} else {
			alert("Ajax call failed!");
		}
	}
}
//Parse XML For Ajax Request
function parse(xmlRequest){
	var xmlDoc = xmlRequest.responseXML;
	var message = xmlDoc.getElementsByTagName("Message")[0].childNodes[0].nodeValue;
	var errors = xmlDoc.getElementsByTagName("Error");
	if(errors.length!=0){
		for(var i=0;i<errors.length;i++){
			message = message+"\n"+errors[i].childNodes[0].nodeValue;
		}
	}
	alert(message);
} 
//===================Ajax Frame End======================================


Example: html call BW, skip J2EE framework.
<!DOCTYPE HTML>
<head><script>
calculate=function(){

	var a  = document.getElementById("007").value;
	var b  = document.getElementById("009").value;

	var Host = "";
	var Post = ""
	if(verify(a)&&verify(b)){

		try {
		
			var posturl = encodeURI("http://10.114.206.147:40252/myself/intfProcess_Definition-service.serviceagent/portTypeEndpoint1");

				}
			}
