Calling a class from a servlet

Question

Hello,
I have created this class for creating a connection pool, which I want to use in a web app with a bunch of servlets. My plan is to put this class in the classes folder with all my other classes (I hope that works). But first I am seeking an answer to this question:
How do I get a connection from the pool from my other servlets? I have tried this line in a servlet:
Connection ocon = ConPoolInit.getConnection("java:comp/env/jdbc/CraigsList");
...but it does not compile. Any suggestions for what this line should be to get a connection from the pool (see class below) are greatly appreciated.
Thank you,
Logan
package CraigsClasses;
import java.net.*;
import java.io.*;
import java.sql.*;
import javax.naming.*;
import javax.sql.DataSource;
public class ConPoolInit2 {
public static Connection getConnection(String lookup) throws NamingException, SQLException {
Context context = new InitialContext();
DataSource ds = (DataSource)context.lookup(lookup);
Connection ocon = ds.getConnection();
context.close();
return ocon;

Thank you DrClap for helping.
I put in this line to import the ConPoolInit2.class.
import ConPoolInit2.*;
Error say the package does not exist. But to modify the classpath seems like a lot of work.
I must ask again for your expert opinion: is this the best method for connection pooling?
If I put these lines in every servlet, it works. But is it right? Is a separate class better?
public static Connection getConnection(String lookup) throws NamingException, SQLException {
Context context = new InitialContext();
DataSource ds = (DataSource)context.lookup(lookup);
Connection ocon = ds.getConnection();
context.close();
return ocon;
} // private Connection getConnection(String lookup) throws NamingException, SQLException {
Should ConPoolInit2 be a servlet?
This system will eventually be capable of handling millions of users such as
another craigslist.com or another ebay.com. Any suggestions are very welcome.
