RE: ClassPath Woes - What the Heck is happening.

The way Shannon does it is also the way I do it.  I just put a monitor
around it so if the environment variable value already exists my program
happily skips along.  Never had any troubles to date, but I haven't used
Java and RPG together extensively.

Monitor;
  setClasspath();
On-Error *All;
EndMon;

...make my java calls...

That's very strange, Shannon.  Never heard that one before.  I don't
think I've ever added the CLASSPATH envvar from inside my RPG program.

I can understand the reverse being true, that adding the CLASSPATH
envvar from inside an RPG program *doesn't* have any effect - that could
happen if the JVM had already been started by another RPG program - the
CLASSPATH environment variable is only fetched by RPG runtime when it
has to start the JVM.
