You need to set values for
jboss.server.name - > Name of ur server config( default is "default").. In ur case, it is myserver
jboss.server.base.url --> Base dir for ur server configurations, in ur case , /home/myhome/jboss/server
You have to return the URL representations of these directories. Look in ServerConfigImpl.java for more details on these properties. If you set these at startup , you can bypass the default values(I think).
PS: I have not tried this , but would really be interested in the result ;-)
