ClassNotFound Error on Linux

Hi, I'm trying to figure out if I can even do this; I have a linux box (redhat 9.1) running Apache/2.0.48 (Unix). I have installed java runtime 1.4.2_04. I have Mysql 4.0.13 and MySQL J installed and the jar is mysql-connector-java-3.0.16-ga-bin.jar.

I have the jar file in the JAVA_HOME/jre/lib/ext directory and my CLASSPATH is set to point to the directory which houses the jar and the com/mysql/jdbc/Driver path.

When I run my applet from the localhost machine it runs fine in Firefox, it connects and returns a recordset. Same if I run in Netbeans. The problem arises when I try to run it from another machine, a Windows 2000 box with I.E. 6. I get the standard class java.lang.ClassNotFoundException error when doing the
I moved the applet .class file to the htdocs directory under Apache before I tried the remote connection.

Can I run the applet from a remote machine and if so, why do I get the following error in the Apache error log:
[error] [client] File does not exist: /usr/local/apache2/htdocs/com
It looks like it is trying to look for the com/mysql.... classpath from the web directory. I'm really new to this so any help would be greatly appreciated. Here is my code:

import java.applet.Applet;
import java.awt.Graphics;
import java.sql.*;

public class test2 extends Applet {

StringBuffer buffer;

public void init() {
buffer = new StringBuffer();

addItem("initializing... ");

void addItem(String newWord) {

public void paint(Graphics g) {
//Draw a Rectangle around the applet's display area.
g.drawRect(0, 0, size().width - 1, size().height - 1);

//Draw the current string inside the rectangle.
g.drawString(buffer.toString(), 5, 15);

Connection conn;
String url = "jdbc:mysql://";
Statement stmt = null;
ResultSet rs = null;
int cnt = 0;

try {
} catch (Exception ex) {
g.drawString("Vendor State:" + ex.getMessage(), 5, 30);
g.drawString("Vendor State:" + ex.getClass(), 5, 45);
try {
conn = DriverManager.getConnection(url, "paul", "xxxxx");
stmt = conn.createStatement();
rs = stmt.executeQuery("SELECT pcname from player");
int linecnt = 20;
while ( {
linecnt = linecnt + 15;
String player = rs.getString(1);
g.drawString("Name: "+player+" Counter: "+cnt, 5, linecnt);
} catch (Exception ex) {
g.drawString("Vendor State:" + ex.getMessage(), 5, 60);
g.drawString("url:" + url, 10, 75);
