The question basically says it all. I'm trying setup up JavaDB on my virtualbox running Ubuntu 9.10.  

I have the package downloaded and installed through the package manager, which I believe is the right to go about it. I have also installed the Eclipse's Data Platform Tools. I've been following this tutorial here: <http://www.vogella.de/articles/EclipseDataToolsPlatform/article.html>.  

I'm stuck at the driver definition step. When I select the driver template from the Name/Type tab and the jar file in the Jar List tab, the OK button is never enabled. At the top of the New Driver Definition dialog it says 'Unable to locate Jar/zip in the file system as specified by the driver definition: derby.jar.' I assume this is the problem. Any help or links to a better tutorial would be much appreciated.
