 Is this possible using grass jni. I looked into its library but could not
 find functions for these commands

See http://sorokine.info/grass-jni/ - it is there only for historical reasons.

 If not, is there another way I could do this using java

Perhaps through jython in order to use the nice new Python bindings?
Of course also via the new vtk-grass-bridge with JAVA bindings.

 r.mapcalc map.red = r#map
 r.mapcalc map.green = g#map
 r.mapcalc map.blue = b#map

This:

r.mapcalc map.red = r#map ; map.green = g#map ; map.blue = b#map

is more efficient, as it only reads the input map once.

 thanks a lot, do you know how to get
 their red, green, blue values (0-255)

for the basic palette, try the r.colors.out in newer versions of
GRASS.


or create 3 new maps with r.mapcalc's # operator, then r.out.xyz
for those:

r.mapcalc map.red = r#map
r.mapcalc map.green = g#map
r.mapcalc map.blue = b#map
