Installing JDK in a FHS-compliant way

Question

I'm trying to install JDK on elementaryOS 0.3, but I'd like to do it in a FHS-compliant way. I've read a couple of answers about this topic, and a lot of them state that a program could be installed in /usr/local/. I was going to create a java folder in /usr/local, but before to do that, I started to read the FHS 3. It said the following:

4.9.2. Requirements

The following directories, or symbolic links to directories, must be in /usr/local

Directory Description

1. bin Local binaries
2. etc Host-specific system configuration for local binaries
3. games Local game binaries
4. include Local C header files
5. lib Local libraries
6. man Local online manuals
7. sbin Local system binaries
8. share Local architecture-independent hierarchy
9. src Local source code

No other directories, except those listed below, may be in /usr/local after first installing a FHS-compliant system.

This means that I have to unzip the JDK file and put, for example, the JDK's bin folder inside of /usr/local/bin, JDK's manuals in /usr/local/man, and so on with the other folders?

Answer 1

Given that elementary OS is based on Ubuntu, you have a couple of options.

1. You can install OpenJDK using the openjdk-7 or openjdk-8 packages; I'm not sure the latter are available in elementary OS though.

2. You can re-package an Oracle JDK (including JDK 8) using the java-package package which is also available in elementary OS. This will give you an FHS-compliant package which will also integrate nicely with the Java alternatives system which is used in Debian derivatives.
