JSP connection/ method problem

Jan 5 2012 3:49 PM
Hi I have a problem in my jsp and java assignment. I am using a method that returns an integer of number of contacts in my database. this is my code (method).

 public int getContactCount() throws SQLException{
        int counter = 0;
        int counter2 =0;
        int total = 0;
        String query = "";
                query = "SELECT id FROM businesscontact";
                String query2 = "SELECT id FROM residentialcontact";
           
            db.connectMethod();
            PreparedStatement ps = (PreparedStatement)conn.prepareStatement(query);
            ResultSet results = (ResultSet)ps.executeQuery();
            while(results.next()){
                counter++;
            }
             PreparedStatement ps2 = (PreparedStatement)conn.prepareStatement(query2);
            ResultSet results2 = (ResultSet)ps.executeQuery();
            while(results2.next()){
                counter++;
            }
            total = counter + counter2;
            db.disconnectMethod();
           
        return total;
    }

I am calling that method in my jsp page. This is the code

<%@page import="db.dbOperations"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Number Of Contacts</title>
    </head>
    <body>
        <h2>Total Number Of Contacts</h2>
        <% dbOperations db = new dbOperations();
        int counter = db.getContactCount();
        %>
        <h4>The total number of contacts is:<%=counter%></h4>
       
    </body>
</html>

Anyone can help why I have a problem please ?
