The json variable is never assigned beyond creating the new, empty, JSONObject. You only use employee and employeeslist. But you never print those out.

You mix Json content type with html format. Try removing html tags at start and end:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="application/json; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
And
</body>
</html>
Finally do not ever use empty catch block. You might miss some important exception that is real cause.
