Perhaps I know absolutely NOTHING about how to properly JAR a file,
but here were my steps:

1) I have a class called ChatGlobals.class whose source code is
configured as so:

[CODE]
package ppowell.val.chat;

public class ChatGlobals {

public static final String chatBrandName = "VÄL CHAT OP";

// DISPLAY VARS
public static final String font = "<font face=\"Georgia, Verdana,
Arial, Helvetica, sans-serif\" size=2>";
public static final String smFont = "<font face=\"Georgia, Verdana,
Arial, Helvetica, sans-serif\" size=1><b>";
public static final String req = "<font
color=cc0000><b>*</b></font>";

// BRANDING
public static final String brand = "Välsignalandet";
public static final String brandHTML = "V&#228;lsignalandet";

// HOST VARS
public static final String homeDomain = "http://valsignalandet.com";
public static final String cgiDomain =
"http://valsignalandet.com/cgi-bin/cgiwrap/ppowell";
public static final String menubarDomain =
"http://valsignalandet.com/cgi-bin/cgiwrap/ppowell/menubar.cgi";

public ChatGlobals() {}

}
[/CODE}

2) I next "jarred" the clases up into one .jar file using
command-line:

[code]jar cvf chat.jar *.class[/code]

3) I uploaded the newly-created JAR file into /ppowell/val/chat on the
remote server as /ppowell/val/chat/chat.jar

4) I added page imports to chat.jsp:

[code]
<%@ page import="java.io.*, java.net.*, java.util.*,
java.util.regex.*" %>
<%@ page import="javax.servlet.*, javax.servlet.http.*" %>
<%@ page import="ppowell.net.*, ppowell.util.*, ppowell.val.chat.*" %>
[/code]

5) I uploaded chat.jsp to /ppowell/val/chat to become
/ppowell/val/chat/chat.jsp

When I call http://www.mycgiserver.com/~ppowell/val/chat/chat.jsp I
get this:

[code]
500 Servlet Exception
Note: sun.tools.javac.Main has been deprecated.
/~ppowell/val/chat/chat.jsp:16: Undefined variable or class name:
ChatGlobals
   errorMsg = "<li>" + ChatGlobals.font + "<font color=cc0000>Please
enter a nickname</font></font><p>";

[/code]

Perhaps I just plain don't understand how to do this JAR/JSP thing,
but I thought I got it right.  You zip it up, put it in the right
directory, you reference by page imports and it works unless you have
class-related exceptions.

What could I have missed that perhaps someone more astute in Java than
I, which at this point is about 90% of the known universe, can find?
