Enabling Java for Chromium Web Browser on Linux

Enabling Java for Chromium Web Browser on Linux (for webSDR)

First install Java jdk or jre from http://www.oracle.com/technetwork/java/javase/downloads/index.html

JRE = runtime only you cant compile java only run java

JDK = You can compile and run java

I installed the JDK as I am also a java developer (1.7 latest is fine) jdk-7u11-linux-x64.tar.gz

Change to the directory where you saved the download

Open command terminal

cd /home/anton/Downloads

tar -cvf jdk-7u11-linux-x64.tar.gz

It will unzip all the files creating a directory  similar to this jdk1.7.0_11cd /usr/lib/chromium-browser/plugins

cd jdk1.7.0_11

Need to add the java plugin into the Chromium Web Browser
The path mite be different on your Linux change to fit

cd /usr/lib/chromium-browser/plugins
sudo ln -s /home/anton/Downloads/jdk1.7.0_11/jre/lib/amd64/libnpjp2.so libnpjp2.so

Need to change the System default java to point to new java JDK I know installed above

sudo update-alternatives --install "/usr/bin/java" "java" "/home/anton/Downloads/jdk1.7.0_11/bin/java" 1

Know take you browser to http://zr6aic.giga.co.za:8901  and see if webSDR is know working.

Here is a map of webSDR receivers.
