Mpainkiller's advice worked for me as well. However you must install java into your operating system before you may do this (If you have not manually installed it already, I think you probably don't have it unless some other program has installed it along with itself). Here are the download and installation instructions:
I downloaded the self extracting version, as I had no idea what an RPM package was, and wasn't about to bet on whether it was included on my OS or not (I'm using Ubuntu 11.10, by the way).
Note: I must mention that in the installation instructions, where it says:
"Change the permission of the file you downloaded to be executable. Type:
chmod a+x jre-6u<version>-linux-i586.bin"
at first I did not realize, "jre-6u<version>-linux-i586.bin" is just the name of the file download, which as of the time of this post is "jre-6u29-linux-i586.bin".
Hope this helped someone!!! I know it must be fairly easy to stumble upon this problem.
Oh, and for newer users, it may be worth mentioning that it is wanting you to type these instructions into a program called "terminal" available by typing its name into the dash search function.
