[Gvsig_english] v1.9 alpha on Ubuntu 8.10

Sun Feb 15 13:24:57 CET 2009

I have turned off the visual effects (right click the desktop and select
preferences. Visual effects tab and select the 'none' radio button) :-)
java -version on the command line returns:
The program 'java' can be found in the following packages:
 * java-gcj-compat-headless
 * cacao-oj6-jre-headless
 * gij-4.2
 * kaffe
 * cacao
 * openjdk-6-jre-headless
 * jamvm
 * gij-4.3
 * sablevm

I also tried this:
colin at mullaway:~$ '/home/colin/gvsig-oade-1.0.1/jre/bin/java' -version
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)

Does this help?

Cheers

Colin
