ajax - jquery Ajax URL 関数呼び出し

Question

これは私のJquery Ajax Partです:-

$.ajax({
    type: "GET",
    data: 'name=' + dept+"&emp=1",
    async: false,
    url: "master/loginCreateUser.jsp/getEmpName()",    //i m not able call thisgetEmpName Function call in this location
    success: function(data) {                    
        for(var item in data){
          $("#empName").append("<option>" + data[item] + "</option>");
        }                     
    }
 });

これは私の loginCreateUser.jsp ページです:

<%!
public ArrayList<String> getEmpName() throws Exception { 
   ArrayList<String> emp = new  ArrayList(); %>          
   <% String s1 = request.getParameter("name"); %>
   <%! emp =  new UserRights().showEmp(s1); %> //i am not access this s1 variable on this location,it shows the error can't find symbol"
   <% 
     return emp;
}
%>

jspページからこの関数を呼び出すにはどうすればよいですか?
