If there isn't a config file option for the run user...
Basically it sounds like all the files and folders created from the install are owned by the user, root.
As root, you can do a chown -r [[user name]] [[folder/file]]
chown (change user) -r (recursive, goes through the subfolders as well) [[user name]] tstrick [[folder]] the folder(s) JBoss needs to execute and run.
chmod a+x [[file]]
chmod (change permissions) a+x (owner, group, others gain executable permission) [[file]] (the file that you need to execute to run)

Am I correct, would those options work? I'm not sure which is a best practice...
