connectionpool jar file

I am trying to compile my servlet but I keep getting an error.  "can't find connectionPool in the class myreminder".  I was told that I am missing the connectionPool jar, can anyone tell me where to get it???? I have been on the Java Sun site.  I need this rather quickly.  Thanks!!!!!!!!

This is part of my code:
package myreminder;

import ConnectionPool.*;
import java.sql.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;


public class myremLogic {
   //connection pool
  public void setConnectionPool(ConnectionPool pConnectionPool){
    connectionPool = pConnectionPool;
  }
