Connection
I am maintaining a project on
servlet database is mysql.
I have a connection instance variable con.
I am using the same connection in many methods. (The code is below just typed one of the methods for explanation)
Is this the correct way to use the connection object in all the methods
or should i have seperate connections in all the methods ?
I have observed that the page does not get properly loaded if i use the instance variable con in all the methods.
But if i open and close connections in all the methods there will be lot of overhead so can anyone suggest a better way...
public class DCRDoctorData extends HttpServlet
{
Connection con;
public void doGet(HttpServletRequest req,HttpServletResponse res) throws ServletException,IOException
{
con = ConnectionHandler.getConnection(dbname);
add1();
}
private void add1()
{
Statement stmt = con.createStatement(); // using the instance variable
}
}
