I'm new to Ubuntu, so I really need instructions to be fool-proof. The instructions I have found on the web do not work on a default install. Ideally the JRE or JDK would work with Firefox. I need to be able to access a web-based java/jre financial application. Are there any instructions on how to do this, which assumes you have a default installation? I could not get either of these instructions to work: <a href="http://www.cs.cornell.edu/~djm/ubuntu/#java"> http://www.cs.cornell.edu/~djm/ubuntu/#java</a> <a href="https://wiki.ubuntu.com/RestrictedFormats">https://wiki.ubuntu.com/RestrictedFormats</a> Both say "java-package" is unknown. thanks
