Import and jar's

Question

I have created a small set of utility classes that are in a package. I placed them in a directory and set my CLASSPATH variable to it. I am able to use them when the just stand there as class files in their appropriate directory tree.
What I was wondering is: is there a way to zip them up into a jar and still import them into a new program from the jar?

Answer 1

Not quite what I am after. The problem is that the code won't compile when it's packaged in a jar, but will when I explode it out into the directory.
class JCalendar
package ameyer.util
import javax.swing.*;
class JCalendar {
JCalendar (){
}if I place the resulting class file in the directory "C:MyClasses\ameyer\util\JCalendar"
and set my CLASSPATH=.;"c:\MYClasses"
I can use them just fine in other programs just fine by using
import ameyer.util.*;
However if I JAR the classes and place the jar in the directory "C:\MYClasses" then the import does not work.
