Doing this avoids having to specify their jars on the classpath.  On our
V5R1 machine, this directory is /QIBM/ProdData/Java400/jdk13/lib/ext.
At least, that's the JDK version.  I can't find a separate JRE one, but
I'll post again if I do.

I don't know about this, but I expect it's similar to the above.  Mind
you, since it's to do with security, you may want to get a comment from
someone who does know about it.

Could you post the script?  Unless it's very complex it should be simple
enough to tell you what is needed to make it run under QShell (I'm
assuming it's a Unix-style script, here).

ICBW, but I don't think you'll need an HTTP server running on the
machine where this application is running; just one listening on the
relevant port on the machine that the application is connecting to.

You can set the default version for a user by creating a file in their
home directory called SystemDefault.properties.  This file should
contain the following line:

        java.version=1.3

Personally, I think your vendor is being rather lazy.  If they want to
sell a cross-platform solution that targets the iSeries market then they
should take the time to learn a little about the platform.  But you
don't need me to tell you that. ;-)

HTH.

Cheers,
