[GRASS5] Does GRASS have Java?

GRASS GRASS developer

I'm involved in a group project of the Faculty of Information Technology,
University of Moratuwa, Sri Lanka (Any idea where _that_ is?) based on GRASS5.

However, we have to do it in Java, and at the moment we can't locate any .java
file inside the GRASS source (Panic!!!). We'd heard that there was this Java
wrapper for GRASS4; could it be that Java support is discontinued in GRASS5 or
we are having really bad eye-sight?

Any guidance on GRASS+Java is very much appreciated. Please help. Save a life.

The GRASS-JNI code is in the src.garden/grass.java subdirectory, but:

1. It's present in 5.3 (the CVS trunk), and in the 5.0.0, 5.0.1 and
5.0.2 releases, but not in 5.0.3 (a lot of unmaintained code was
removed from the CVS release branch between 5.0.2 and 5.0.3).

2. It hasn't been updated for GRASS 5.x, and so may not work in its
present form.

Hy,
we are currently developing JGrass, a java interface for Grass to get rid of
the Xserver and all the portability issues, and to be able to exploit some
newer software tecnologies. The display-system is there but needs some
stabilization. The architecture is already choosen.
JGrass gives the possibility to easily implement new modules in java.
JGrass will be officially presented in Bangkok.

Feel free to visit the (not so updated :frowning: ) project-site and to contact the
involved people. We'll be glad to introduce you to the project.
Visit:
http://bedu.ing.unitn.it/~daniel/fantastiso/login/ under JGrass.

Cheers,
Andrea

PS: The JNI-Java wrapper is there. Just search Sorokine's work in the
src.garden directory. I hasn't been updated for a long time and it loads the
whole environment every time you need to make a jni call. JGrass is the way
java-interested developers should now go :slight_smile:
