Answer 1

create a java bean, which is just similar to a java class and put the database connection there so you wouldn't have to include that code in all you jsps everytime you connect to the database
this is for DbConnection.java
package connection;
import java.sql.*;
import java.io.*;
public class DBConnection
     private Connection con;
     public DBConnection()
          try
              Class.forName("com.mysql.jdbc.Driver");
              con = DriverManager.getConnection("jdbc:mysql://localhost/yourfolder?user=yourusername&password=yourpassword");
        catch (Exception e)
             e.printStackTrace();
     public Connection getConnection()
          return con;
     public void close()
          try
               con.close();
          catch(Exception e)
               e.printStackTrace();
}in another bean/class which connects to your database,
say for example this is SelectUsers.java
public String[] selectActiveUsers(int id) throws Exception, SQLException
     try
               con = new DBConnection().getConnection();
               Statement stmt = con.createStatement();
               String ins = "<your select statement>";     
                        stmt.executeUpdate(ins);
                        con.close();
               stmt.close();
         catch (SQLException se)
                System.out.println("SQL Exception: " + se.getMessage() + "not connected");
                se.printStackTrace(System.out);
     }and in your jsp, instantiate the class
users.jsp
SelectUsers su = new SelectUsers();
String[] users = su.selectActiveUsers(1);got it?
