Hi
i have implemented sample dhtmlx scheduler in java with mysql database connection .But when the page load events are not loaded from the database.Instead it show an error message : “Error Type :Load XML Description :Incorrect XML”
/$Rev$/
dhtmlxAjax={
get:function(url,callback){
var t=new dtmlXMLLoaderObject(true);
t.async=(arguments.length<3);

post:function(url,post,callback){

return t;

getSync:function(url){
return this.get(url,null,true)
