Namespace undefined error in javascript to execute ajax method from asp.net page-Collection of common programming errors

I am Using Ajax Pro

I am not getting any error on my machine when i test the web site but getting an error of TimeSheet is undefined (TimeSheet is the namespace) from the hosting.

I get this error in the following cdoe from javascript function

try
{
var response = TimeSheet.DAL.ApexDalc.PopulateDuration(d1, d3);
}
catch(txt)
{
 alert(txt.message);
 return false;
}

alert(response.value.Tables[0].Rows[0].Hours);

I have registered Ajaxpro in the page load with AjaxPro.Utility.RegisterTypeForAjax(typeof(DAL.ApexDalc));

I have added httphandlers in web.config also:

Can you suggest what can be the cause of error in the web site from hosting server?

Thanks
