[teiid-designer-users] Driver list menù

Hi to all, i'm a java developer i'm interested to EII systems, i'm using the teiid-designer in eclipse 3.4.2 on ubuntu 8.10. So, i'm following the quick start found on the teiid project website, the plug-in seems to work fine but when i try to import metadata from a database source, the plug-in drivers menù don't show me anything. Any suggestion? Thanks in advance, Salvatore Incandela.
