This wiki page contains information about using the Java plugin in Firefox on NixOS.
As of 2010-09-15, Firefox 3.6 uses the correct java plugin when nixpkgs.config.firefox.jre = true. For nixpkgs older than 2010-09-15, see below:
From Firefox version 3.6, the old Java plugin located in <JRE>/plugin/i386/javaplugin-oji.so no longer works (source: [1]).
The new plugin is located in <JRE>/lib/i386/libnpjp2.so.
For Firefox to reach the plugins, there are 3 ways:
- put the path of the plugin in the environment variable MOZ_PLUGIN_PATH
- create a symbolic link to the plugin in ~/.mozilla/plugins
- create a symbolic link to the plugin in <FIREFOX-DIRECTORY>/plugins
Help to do each method:
- The MOZ_PLUGIN_PATH way is implemented in NixOS (look at /etc/nixos/nixpkgs/pkgs/development/compilers/jdk/jdk6-linux.nix) but the path given there is the path to the old plugin whcih does not work. You can correct this by changing the if installjdk then "/jre/plugin/i386/ns7" else "/plugin/i386/ns7"; line to if installjdk then "/jre/lib/i386" else "/lib/i386";'. This works but you will see a lot of warnings in the command line when running Firefox because it tries to load all the libraries in <JRE>/lib/i386 as a plugin. You should also install firefoxWrapper (or firefox-3.6.8-with-plugins if you are using nix-env) instead of firefox and set nixpkgs.config.firefox.jre = true in your /etc/nixos/configuration.nix.
- This is an easy way but you should do the same for all users: if you only have jre installed but not jdk: mkdir -p ~/.mozilla/plugins; ls -l `which java` | sed 's/.*-> \(.*\)\/bin\/java/ln -s \1\/lib\/i386\/libnpjp2.so ~\/.mozilla\/plugins/' | bash If you have jdk installed: mkdir -p ~/.mozilla/plugins; ls -l `which java` | sed 's/.*-> \(.*\)\/bin\/java/ln -s \1\/jre\/lib\/i386\/libnpjp2.so ~\/.mozilla\/plugins/' | bash
- The best would be to implement this centrally in /etc/nixos/nixpkgs/pkgs/top-level/all-packages.nix and reach all the firefox plugins this way.
