Hi there,
my question is how to integrate with MySQL database.
i had tried this code, but it return "package java.sql does not exist".

Code:
 
import java.io.*;
import java.util.*;
import javax.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class DBConnection extends HttpServlet {
  public void service(HttpServletRequest request,HttpServletResponse response)
    throws IOException, ServletException{
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    out.println("<html>");
    out.println("<head><title>Servlet JDBC</title></head>");
    out.println("<body>");
    out.println("<h1>Servlet JDBC</h1>");
    out.println("</body></html>");
    // connecting to database
    Connection con = null;
    Statement stmt = null;
    ResultSet rs = null;
    try {
      Class.forName("com.mysql.jdbc.Driver");
      con =DriverManager.getConnection ("jdbc:mysql://192.168.10.59:3306/example",

      "root", "root");
      stmt = con.createStatement();
      rs = stmt.executeQuery("SELECT * FROM servlet");
      // displaying records
      while(rs.next()){
        out.print(rs.getObject(1).toString());
        out.print("\t\t\t");
        out.print(rs.getObject(2).toString());
        out.print("<br>");
      }
    } catch (SQLException e) {
      throw new ServletException("Servlet Could not display records.", e);
      } catch (ClassNotFoundException e) {
        throw new ServletException("JDBC Driver not found.", e);
      } finally {
        try {
          if(rs != null) {
            rs.close();
            rs = null;
          }
          if(stmt != null) {
            stmt.close();
            stmt = null;
          }
          if(con != null) {
            con.close();
            con = null;
          }
        } catch (SQLException e) {}
      }
      out.close();
    }
  }
it's seem like only RecordStore or FileConnector can storing information in a mobile device but how to integrate with MySQL database?
i want to let the user key in UserName and Password then access to my application.
