Does that mean that Java is not suitable for your program because it
does not
have a "math engine"? What functionality do you need? The term "math
engine"
could be almost anything!
Why are you using Java?

Code re-use is a very popular theme in software engineering. It doesn't work
too well if the code you are trying to re-use was not written to be
re-used, or
not even debugged.

Maxima is not written in any old hacked up "implementation of lisp."
Jatha claims to be
"a large subset of common lisp". What makes you want to debug it?

All you need is a linkage between lisp and Java.. see, for example.

The link between lisp and maxima is simple. For example, to invoke the
maxima
function "foo" you can call (in lisp) the function $foo.
