Enabling java plugin in Chromium on Linux

Hi there,

In certain situations you may need to use java plugin in chromium to access certain functions in a website such as server's console accessed via IPMI page.

On Linux ( I use Ubuntu 18.04), install icedtea-plugin package:

sudo apt install icedtea-plugin
To enable chromium to run java, make a symbolic link of icedtea plugin to plugin directory of chromium:

sudo ln -s /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so /usr/lib/chromium-browser/plugins/
Have fun!
