How can a GNU/Linux machine be set up to automatically update a newer version of the Java Runtime Environment (JRE)? The difficulty is wanting to use a newer version of Java (Java 7, at present) and also be reasonably up to date with bugfixes, especially security updates, without excessive manual work.
You can rely on the the O/S distribution, but they are naturally conservative and therefore provide only bug-fixed versions of an older Java version. No Java 7 on RedHat 6.
You can manually download the JRE from the Oracle website, and set your
JAVA_HOME environment variable to point to it. But that is impractical when you want multiple machines across an enterprise to be updated.
Is there a practical way to, for example, use Java 7 on RedHat 6 and have the Java 7 JRE automatically (or semi automatically) updated as Oracle release bug fixes for it?
