using Ms access and jdbc not able to get the output

hi all i am using microsoft access for the 1st time.. before that i used oracle 9i and sql server.. i also want to deal with access database ..i just simply want to insert two values in my datatable created in access..

my DNS name is "db1" and my datatable name is "DriverDetails"

The code goes like this..

and my servlet code is...

import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
 
public class DriverDetails extends HttpServlet
{
    PreparedStatement stmt;
 
public void service(HttpServletRequest req,HttpServletResponse res) throws IOException, ServletException
{

PrintWriter pw=res.getWriter();
    pw.println("hello");

String str="insert into DriverDetails values(?,?)";
    String dataSourceName = "db1";
        String dbURL = "jdbc:odbc:" + dataSourceName;
        try
        { 
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        Connection con = DriverManager.getConnection(dbURL, "","");
        PreparedStatement ps=con.prepareStatement(str);
        int DriverID=Integer.parseInt(req.getParameter("DriverID"));
        String DriverName=req.getParameter("DriverName");
        ps.setInt(1,DriverID);
        ps.setString(2,DriverName);
        ps.executeUpdate();
                
        pw.println("record Inserted");
        
 
        }
        catch(SQLException e)
        {       
            System.err.println("SQL Exception found!");
        }
        catch(ClassNotFoundException cf)
        {
            System.err.println(cf);
        }
}
}

The problem is when i insert values in the html page and click on the submit button i am only getting the output as "hello"

Please suggest me what to do..

thanks,

You are not committing the update, nor do you close the connection. Doing either of those things should cause the update to be visible. However closing the connection is mandatory in web applications. I'm surprised you haven't run into problems with Oracle, if you didn't close your connections.
