compiler error with import

I am trying to compile these codes using jdk1.4.2_11. These codes compiled successfully with 1.3.1_17 but with 1.4.2_11, I am getting a compiler error with import IVServ and import ServeletIncompleteException statement below. Both classes are located in the same directory as the source code.

Do I need to bundle those referred classes in a package?

package test.ip.server;

import java.io.*;

import java.util.*;

import java.net.*;

import IVServ;

import ServletIncompleteException;
