And the *package* name is "java-1.7.0-openjdk", indicating which java
upstream it comes from. The "yum list" format gets pesky to process,
but I find this really helpful to produce a sorted list of all
installed packages.
rpm -qa --qf '%{name}\t%{version}\t%{release}\n' | LANG=C sort -n
I'd also strongly urge dropping all the "java-1.6.0-*" packages on the
floor. Java 6, aka "java-1.6.0" in Sun's actual software repositories,
has basically fallen off the support truck. The "update-alternatives"
tools, run post-installation of tools like java or smtp servers, tries
to negotiate which tool you get by default when you just type "java".
But it's an adventure, because you typically wind up with a default of
whichever tool you installed last. So if possible, pick *one* java
version, and clear away the others.
The only really problematic package for this is the jdk RPM's for Java
6 from Oracle, which have some dependencies that mismatch Red Hat's
layout. If you need to use Oracle's Java 6 JDK, you're in
compatibility hell most easily resolved with my little add-on widget
at https://github.com/nkadel/java-1.6.0-sun-compat-srpm. JPackage used
to publish bundled compatibility packages, but I've found it difficult
to resolve dependencies with their other packages, and the weird
Sun.Oracle licensing made that awkward. Oracle is now supporting
openjdk-1.7.0 almost exclusive.
Basically, at this point, get off Java 6 if you can. Like supporting
out of date versions of Samba, it's usually not worth the pain.
