I have tried all of the solutions I could find in this forum. Particularily the edits to hsqldb-ds.xml, and ensuring I have no spaces in my path names. None of these have solved my error. Has anyone seen this error or know the problem's solution?
I'm having the exact same problem. Same setup except for a different JDK.
Have you found a solution yet? I'm still looking.
I had the same problems on my SuSE 9.2 OS.
My solution was to run JBoss as the same user that was logged into the X-Windows System (alternatively you could log in as the default jboss user).
If you use the first approach, you need to adapt the rights of some files. I did it that way:
]# chown theuser:thegroup -R /opt/jboss/server/*
I hope it helps
