install Java on Ubuntu the easy way
On visiting the Java download website they gave some complicated instructions on how to install the JRE. After going through the steps explained it ended up not working anyway as Firefox still did not have the JRE available . I was desperatly looking for a solution when I gave the Ubuntu software installer from the application menu. There it was the Java JRE but it had no install button. This was cured by navigating to the edit menu and at the bottom selecting software sources, and on the Ubuntu tab clicking all the check boxes. Now I returned to the selection and let the install begin.
In now time at all it installed and Firefox now have the JRE available.
