JDBC connection to a Progress database from Oracle EDQ (aka

We have access to a new tool from Oracle - EDQ - which should allow us to connect to our existing Progress databases through a JDBC connection. But I can't get it to work. I've installed the Progress drivers, and tested them so I know that the network connectivity works. But I can't get EDQ to recognise the Progress driver. I've also folowed the Oracle instructions for adding JDBC drivers to their tool. My only other option is to create a JNDI file for the connection, and I'm just wondering if, [a] anyone has managed to get this working or [b] if anyone has a working JNDI file that I can modify to get the connection working. Thanks
