hi,

are there any final solutions found yet for the problems using the
JSci package with JBuilder 5?

I'm very new to JAVA and am playing with it at the moment. I want to
make some plots and have been using Leigh Brookshaw's source code up
until now. Today I found this package and this seems really nice and
I wanted to test the GraphDemo.java program.

The error messages I get (see below):

Wonder if there is a quick fix to this problem yet. I know that I'll
be able to make it work with a lot of effort but ...

Thanks in advance,

Edward
