So I found a solution and thought I'd post it here for anyone who found this post. I used the Fat Jar Eclipse Plugin at sourceforge http://fjep.sourceforge.net/ It allowed me to export my project as a single jar and include any external jars I was using. I tried for days to get the extracted jar to work as class files, so when I found this plugin it was a welcome relief. If anyone has any idea what I was doing wrong though; I'd love to hear it. I included the /org directory in my project and added it as a class folder to the build path, but Class.forName("org.postgresql.Driver").newInstance(); always failed.
