Where is the jython-21.class located and what is your current directory
when you start the installer?

I can see it tries to find the class file at the path
/home/install/java/jython-21.class. Is that where you have it? If you
does, then your classpath is correct.

Some IOException is occuring while the installer attempts to locate the
.class file and open it as a ZipFile. Unfortunately, the installer
doesn't print any information about the exception and that makes it a
little harder to analyze.

Please check that your copy of jython-21.class looks alright. That it
have some sane access rights. That it has the right size: 2.780.495
bytes. That it is located on a local filesystem.

That does not work on any of the JVMs I know of.

That should work for most JDK based java2 VMs.

If your VM is a JDK1.1, you will also need to added the classes.zip to
the classpath:

   java -classpath $JAVA_HOME/lib/classes.zip:. jython-21 -o jython21

where JAVA_HOME is the installation location of your java VM.
