Classpath is like path ;) More about (in german):
http://uebb.cs.tu-berlin.de/infet/classpath.html

No, it is output directory for JBuilder. You can set it, ex.:
SET CLASSPATH=c:\projects\test2\classes\;%CLASSPATH%
BTW: JBuilder do it (in Messages: 'java -classpath "..."'), if you runs
the application from IDE ;)

Package is like Delphi Unit, is defined... as first in your class, ex.:
package test2;

The path to image should include the full name of package:
toolkit.getImage("test2/images/0196.png");

You are using absolute path.

Yes. If you use toolkit, you must use Mediatracker. With
ClassLoader.getResource() you can read resources (like text files or
images) from classpath or jar files.

good luck
