Java Servlet connection to mysql

Can someone give me a simple source code of java servlet for connecting to mysql database?

import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class DBServlet extends HttpServlet
{
private Connection con;
private PrintWriter out;

public void init(ServletConfig conf) throws ServletException
{
super.init(conf);
try
{
class.forName("com.mysql.jdbc.Driver");
con =DriverManager.getConnection ("jdbc:mysql://localhost:3306/NomDeVotreBase", "VotreIdMySql", "VotreMdpMySql");
}
catch(Exception e)
{
System.out.println(e);
}
}

public void service(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
{
res.setContentType("text/html");
try
{
out = res.getWriter();
out.println("<html><head><title>");
out.println("JDBC Servlet");
out.println("</title></head><body>");

Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM essai");
out.println("<UL>");

while(rs.next())
{
out.println("<LI>" + rs.getString("nom"));
}
out.println("</UL>");
rs.close();
stmt.close();
}
catch(SQLException e)
{
out.println("Exception SQL");
}
catch(IOException e)
{
}

out.println("</body></html>");
out.close();
}

public void destroy()
{
try
{
con.close();
}
catch(SQLException e)
{
;
}
}
}
