Jens,

The Java Native Interface (JNI) is the API set used to allow
a Java program to interact with 'native' code.  The JNI
is fully supported and operational in our Java implementation.

Since JNI only defines interfaces for C and C++, I have
also started work on an 'MPE Class Library' that permits
any XL-resident code, written in any language, to be
called from Java without needing to write JNI stubs.
(Essentially, the MPE Class Library is itself a big
generic JNI stub).

If you're comfortable with C & C++ programming, a custom
designed JNI program will give you the best performance;
see a book such as 'Essential JNI' from PTR, or my Java
tuturial on Jazz (one section covers JNI with examples).
If you prefer trying the class library, it is available
from the Interex Shared Source website for download.
