Not sure if this is the best solution, but if java is forced to be sun java it does start: eg JAVA_HOME=/usr/lib/jvm/java-6-sun openjump works

fwiw Sun's Java is the only one installed on the disc. Open-JDK is removed.

will adding this to the end of install_openjump.sh:

echo "JAVA_HOME=/usr/lib/jvm/java-6-sun" >> "$USER_HOME/.profile"

cause any trouble for any other Java projects on the disc?

if it would, I'd suggest editing openjump.desktop and changing the Exec= line to be like

Exec=JAVA_HOME=/usr/lib/jvm/java-6-sun openjump

and hope for the best.

Other Java projects (notably gvSIG) use JAI as well, do they have the same problem?

oops, forgot to export it

echo "JAVA_HOME=/usr/lib/jvm/java-6-sun" >> "$USER_HOME/.profile"
echo "export JAVA_HOME" >> "$USER_HOME/.profile"

I'm no specialist, but I'm pretty sure that in that case specifying JAVA_HOME is not needed anymore.

Replying to hamish:

Probably yes,

gvSIG directly calls the java binary of /usr/lib/jvm/java-6-sun/bin on its starting script.

As gvSIG is installed using a debian package, the sun JVM is marked as a dependency so if you remove sun-java6-jre from the disk the gvSIG package should be marked to be removed as well.

gvSIG dev team has plans to support OpenJDK (and probably get rid of JAI) but it won't be ready until 2.0 release, I'm afraid.

Best.

fixed in rc9
