Urgent Lost connection during query !

Question

Hi guys,
I'm using Servlet which is running in Linux Operating System and is using MySQL for back-end. This server uses Apache Web Server and Tomcat.
after a moment of inactivty the servlet give me this error message
"Lost connection to server during query"
i initialise my connection into de init() method like this :
public void init(ServletConfig config)
          throws ServletException
     super.init(config);
     // Chargement du driver JDBC
     try
          Class.forName("org.gjt.mm.mysql.Driver");
          connexion = DriverManager.getConnection("jdbc:mysql://localhost/iscom", "login", "password");                         
.... here is the rest of the code i used
public class index extends HttpServlet{
Statement commande=null;
private Connection connexion=null;
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
try
commande = connexion.createStatement();
ResultSet rs = commande.executeQuery("SELECT ...")
}catch
commande.close();
I also use the destroy method
Thank everyone !

Move your code from init to doGet/doPost. In other words, connect to the database just before firing the query and disconnect after that.
