I have tried sending the value as shown(code), but no value is being caught in JSP.

It is showing null value in jsp page.

this is javascript/ajax code

Code:
var emp = document.getElementById("Employee").value;
var url_temp = "print_emp.jsp?Employee="+emp;
alert(url_temp);


var xmlhttp;
if (window.XMLHttpRequest)
{
	// code for IE7+, Firefox, Chrome,
...
