Is there any way to get Java on Ubuntu 8.04?

Using System->Administration->Software sources [Ubuntu software tab] please enable (Check the checkbox) all the showed repositories rows.

Then open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo aptitude update
sudo aptitude upgrade
sudo aptitude install sun-java6-jre sun-java6-bin sun-java6-plugin

give your user password when requested, you don't see nothing when you type it, then press enter.

You will find wifi-radar under the Applications->Internet menu.

Always useful is the online Ubuntu doc https://help.ubuntu.com/8.04/
Hope this helps

okay i did everything you said and it all worked fine except

"You will find wifi-radar under the Applications->Internet menu."

I cant find that and I tried to open something with Java and it still didnt work.

Should I restart or something?

Sorry, the "You will find wifi-radar under the Applications->Internet menu." have no sense here.
Please read my 2.nd reply...

Thank you
