Google found exactly one occurence of an JBoss5-rpm-file:

jboss-5.1.0-4.1.noarch.rpm

(see here ->)Google

that was last September (2009) and I downloaded and installed the file on openSuse 11.2, and everything seems to work fine.
It installed JBoss5 as a Service and placed the files in some linux-usual directories (with links).

But meanwhile this location disappeared.

is there another recommended (maybe better) way to install JBoss5 on openSuse 11.x ?
