JBoss is the worlds most popular (and least complex) J2EE server. Recently I wrote a tutorial on getting JBoss working on OpenSuse 10.2 for a client of mine. The tutorial is NOT complete because the packages built by JPackage are primarily intended for Redhat systems (even though they are suppose to be distribution agnostic.) I will update it, in a couple days, with the changes I applied to get it working but I thought someone might find the information useful enough in its present form.
