jQuery.ajax({
type: "POST",
url: url,
datatype: "xml",
data: {"action":"BayassetChangePagebean.getUserOrCoordinatorAjax","assetsNum":assetsNum},
beforeSend :function(xhr){
xhr.setRequestHeader("Ajax-Request", "true");
},
success: function(xml){
jQuery(xml).find("user").each(function(){
var userName = jQuery(this).attr("userName");
var userId = jQuery(this).attr("userId");
var userType = jQuery(this).attr("userType");
if(userType=='coordinator'){
jQuery("#coordinatorTD").append(userName+" ");
}else{
document.getElementById('currentUserTD').innerText=userName
}
});
},complete : function(){
document.getElementById("form1:outgoingUserName").value=document.getElementById('currentUserTD').innerText
}
});
后台记得设置下 setContentType("text/xml"); 返回的时xml格式的字符串就可以了。

推荐你使用ajax + json
我这边有个struts2 + ajax + json的例子，你看一下或许会对你有帮助

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;
这个你自己去网上下载吧。
public void list(HttpServletRequest request, HttpServletResponse response,PrintWriter pw){
PartsDao dao = new PartsDao();
List<Parts> partsList = dao.getList();
JSONObject items = new JSONObject();
JSONArray result = null;
try {
result = new JSONArray();
for (int i = 0; i < partsList.size(); i++) {
Parts parts = (Parts)partsList.get(i);
JSONObject jsonParts = new JSONObject();
jsonParts.put("ID", parts.getPartsId());
jsonParts.put("name", parts.getName());
jsonParts.put("PP", parts.getBrand());
jsonParts.put("LGBH", parts.getLGBH());
jsonParts.put("TH", parts.getTH());
jsonParts.put("YCBH", parts.getYCBH());
jsonParts.put("DW", parts.getFormat());
jsonParts.put("GG", parts.getAttribute());
jsonParts.put("BZ", parts.getRemark());
jsonParts.put("status", parts.getStatus() == 1 ? "1" : "0");
result.add(jsonParts);
}
} catch(Exception ex) {
ex.printStackTrace();
}
items.put("identifier", "ID");
items.put("label", "name");
items.put("items", result);
items.write(pw);
}
