Hi all, I’ve been tasked with upgrading the jdk from 1.6 to 1.7 on an openSUSE 11.2 box. We use this box to construct an installer for a product. I am a developer, but I’m not the developer of this set of software, nor do I have that much experience with java. And, to boot, I have much more experience with Gentoo and RedHat/CentOS, this is my first time working on a SUSE box, and I’ve never attempted a java upgrade to something not easily supported by the mainstream distro.
So I downloaded jdk-7u2-linux-i586.rpm from the oracle site and it installed to /usr/java/jdk1.7.0_02. I have discovered update-alternatives and made one feeble attempt at just changing the java link. It didn’t seem to do much, ‘javac -version’ still referred to 1.6. So I got to looking and I found what I see as a rabbit hole that I don’t really want to go down with system java paths referring to /usr/lib/jvm and links therein referring to /etc/alternatives and some of those back to /usr/lib/jvm as seen below. Also, not being sure if that elaborate link/file structure is unique to the opensuse supplied jdk-1.6 package(s).
Has anyone else successfully pulled this off? Or are there any words of wisdom regarding this task?

Mmmm… Notice that 11.2 is obsolete, out of maintenance. Unless you are
using evergreen…
