[VPE]We doesn't support x64 platform's now.
Try using a 32-bit JDK. You will probably have to download it from the Sun web site and install it yourself. I have done this for my 64-bit Kubuntu and can run either 32-bit or 64-bit JVM. I typically use the 32-bit JVM for running Eclipse.
mareshkau - we have had 64bit builds for Linux for a couple of months now ;)
rob - the xulrunner binaries are included in the download/update site so should just work.
PeterJ - using 32-bit will/should work; but I assume the reason meetoblivion is asking is to get a "pure" 64bit environment
meetoblivion - sorry for not answering before but I was busy at Devoxx and their network prevented me from doing almost any work.
Which version of JBoss tools have you installed ? Our latest beta at least has a 64bit linux build (http://download.jboss.org/jbosstools/builds/release/3.0.0.Beta1/)
If that still fails it might be a collision of xulrunner 1.9 being installed under you system preventing Xulrunner 1.8 to startup....but lets make sure you got a 64bit build first ;)
