It is there.

I am willing to do that as a test, but we should also think hard about
compatibility with older jdk versions.  Our Debian users are not going to be
able to use your package (without a special download and possibly conflicts
between that download and the supported jdk-1.1.8 version). I guess I can
live with that because it might be a special case.  Also, I personally don't
have a problem with a conflict because I don't use any other Debian packages
that are related to jdk-1.1.8. But to ensure we don't make things too
impossible for our users, we should look at what other distributions do as
well.  Does anybody here know what jdk version is officially supported by
Redhat 7.1? (or 7.2 which is just out today?) Same question for SuSe and
Mandrake (latest versions only, please). If they all tend to be 1.2.x (or
even 1.1.8), I think we should support that version if at all possible.

Note this might be quite easy to do.  There was no trouble compiling any of
the applications under 1.1.8.  So there may be no fundamental inconsistency
between your work and jdk-1.1.8.  The symptoms I am getting are consistent
with the mental model that everything will work if the java invocation is
done without any path to the file name.  That is you just use "java x01"
rather than "java plplot/examples/x01". If that model is true, then the only
additional thing required to make it work is to change all internal
references to trim off plplot/examples and plplot/core from the names. (I
noticed with the strings command that there were such internal references.)
Then, if my model of what is going on is correct, then

setenv CLASSPATH java/plplot/examples:java/plplot/core

should work regardless of jdk version.

Geoffrey, would you be willing to trim off the plplot/examples and plplot/core
from the internal names and see if the above CLASSPATH then works for you?

Thanks.
