In my case Java app is JDownloader. I prepared chroot environment as explained here:
So, I have java installed, added group and user, JDownload files copied, but when I try to run it (as regular user under chroot; I run chroot as root, but once I am in chroot, I switch to chroot regular user):
java -Xmx512m -jar JDownloader.jar
I got some positive messages like loading skins by JDownloader
10 4/6/11 2:15:17 PM - FINER [jd.JDClassLoader()] -> Look and Feel JAR loaded: /mnt/jd/libs/laf/syntheticaSilverMoon.jar
but that's end of the story -- app does not show up. No matter if I use chroot to run chroot environment or openroot, the outcome is the same.
When I run JDownload as chroot-root I got a little more output but at then end exception occurs:
10 4/6/11 2:39:23 PM - FINER [jd.config.DatabaseConnector()] -> Loading database
10 4/6/11 2:39:23 PM - FINER [jd.config.DatabaseConnector(checkDatabaseHeader)] -> Checking database

I have the same Jave installed in chroot and normal system, I can run the same JDownloader in normal system, no problems here.
QUESTION -- what I am missing here? How to run GUI Java app?
Thank you in advance.
