Check your error console in case formj is undefined. Check how you're calling loadContent().

Alternatively, change line 12 to

var stateValue = document.getElementById("dil_ProjectCode").value;

Use String

String stateId = request.getParameter("dil_ProjectCode");

when you type

out.println(stateId);

You must see dil_ProjectCode
