db query Servlet: opening the db

import java.io.*;

import javax.servlet.*;

import javax.servlet.http.*;

import java.sql.*; // JDBC needs this

public class SimpleInq extends HttpServlet {

private static Connection con = null; // used by JDBC

private static Statement stmt = null; // used by JDBC

public void init (ServletConfig config) throws ServletException {

connectJdbc(); // registers the JDBC and opens the database

}

The init method is called only the first time the Servlet is invoked into memory, so there are no concurrency issues.
