The two derby drivers within the drivers node appears twice. One o wach with a red mark in its icon. I think this is causing a conflict because it is unable to connect to the sample databases. I deleted the ones with the red mark and the connection is ok. Why do they appear twice?
Can you describe what version of the product you are using (from the about box)? What steps did you execute to trigger the problem?
The product version is 6.0 Preview (M9, build 070502). I was just trying the "Building a Java Desktop Database Application" tutorial and when I got to create the database (cars_database), it was unable to connect and I noticed in the Drivers node that they appear twice.
I have randomly seen this too.
But I can't reproduce it. I attempted a fix that will avoid registering the drivers for the second time. If you can still reproduce, please reopen and attach your message log and the config/Databases folder in the userdir.
