Based upon some of the search terms that have been used to reach this site I guess I should write up a short post on how to get Java working in Ubuntu 8.04. One way is to symbolically link the proprietary version of Java you are using to your web browser. The other option is to install the open source version of Java, IcedTea.You can run the command “sudo apt-get install icedtea-java7-jre” to get it. It is also possible to get Java 6 to work correctly by linking it symbolically to Firefox, but for me this failed. I would lookin the ubuntu forums here at http://ubuntuforums.org/showthread.php?t=62186 if you wanted to use Java 6 and get it up and running correctly. Maybe you will have better luck than I did in getting it to work.
