I'm using actual Java from Oracle software.

This works very well with all web base Java scripts and automatically ties with Firefox.

On your firefox browser's address bar type this

about:plugins
This will give you the list of enabled plugins in firefox.If you can see the IcedTea-web plugin,this means that the plugin is integrated with your browser or else you need to integrate the plugin manually.

To do a manual integration with your firefox browser just create a soft link of the IcedTeaPlugin.so/libjavaplugin.sofile(whichever in applicable in your case) to the firefox plugins directory (/usr/lib/mozilla/plugins)

cd /usr/lib/mozilla/plugins && ln -s $INSTALL/lib/IcedTeaPlugin.so
Where $INSTALL is the IcedTea-web installation directory (usually it is /usr/local)

Using this PPA not only you get Oracle Java but also it adds an updater to your software sources and you'll always get the latest java update through ubuntu's software updater.
