java plugin of firefox installation on linux platform
Some iLom software(for example oracle iLom) use java jnlp applet(java console) to open remote console of the server. To use this functionality, you need java plugin on firefox installed. Here's the detailed steps:
- Update firefox: yum update firefox, please note that you better remove firefox 64 bit version and use 32 version ones(reason followed). After this, you'll have firefox 10 on the system.

- Install JRE 6: Go to http://www.oracle.com/technetwork/java/javase/downloads/jre6u37-downloads-1859589.html and download jre-6u37-linux-i586-rpm.bin. After that, install the package on the system using rpm -Uvh.(make sure NOT to download 64bits version, as java console only support 32bits java plugin)
- Make java plugin available to firefox: If you are planning to run firefox under root, do the following steps:
mkdir -p /root/.mozilla/plugins/
ln -s /usr/java/jre1.6.0_37/lib/i386/libnpjp2.so /root/.mozilla/plugins/
- if you've installed java plugin before, you'll first need remove it.
- Now restart firefox, and go to about:plugins, you'll see java plugin enabled. Open java console and enjoy!(select /usr/bin/javaws if prompted)
- If you still find the console not prompting up, then it may be caused by java security setting. You can refer to here for WA.
- If you met error like "No appropriate protocol (protocol is disabled or cipher suites are inappropriate)", then one possibility is that firefox/java/libnpjp2.so are not of the same architecture, you should use i386(or x86_64) for all of them.
