I subscribe to what you are saying here Helena.
Also looking forward to see what new tools are on the way in this field.

Yes Hamish,
you are right, even if OpenJump lacks of hydrologic tools. 
We decided not to wait for the free implementations of the Java Virtual 
Machine, since that would block us from staying in line with new tecnologies.
We are now on java 1.5 and the site states: "contrib - needs jdk1.4, several 
contrib packages", so I don't think that jgrass will be soon aligned with the 
free JVM's. As soon as the mustang 1.6 will come, we will jump into that 
since the opengl pipeline which we use is integrated in the JVM.
I don't want to start a discussion on that, just making clear what our 
thoughts are.

In my opinion people should think about what JGrass can give to them, and that 
it tries to keep in line with GRASS formats supplying a possibility to 
develop in java (which is largly used), and not that the JVM is not GPL... a 
lot of work is done by few people in JGrass and I feel strange in thinking 
that someone would not exploit it because of a different flavor of its 
religion.

Best regards,
Andrea
