Cannot connect to internal H2 database [message #1016752]

I was trying to run Jubula inside Eclipse Juno but I am facing troubles connecting to the internal H2 database.

I started with a plain Juno for RCP developers release, installed Jubula into it and tried to connect to the H2 database.

I get an error message: "Database connection failed: Please enter a valid username and password and try again"

which might be misleading as I can see an SQLException "No suitable driver found for jdbc:h2:C:\data\Jubula\database;MUCC=TRUE;AUTO_SERVER=TRUE;DB_CLOSE_ON_EXIT=FALSE" on the console.

I was playing around with different file URIs, but without any luck.

The problem is reproducible on win32, the same setup on a linux machine works out of the box.

Hi,

If the setup works on another machine, then my first suspicion is write access or firewall. Could it be one of those two things?

HTH,
Alex

Gave it another try today and it worked as expected. Might be that installing Jubula in eclipse needs a windows reboot to work? Might be the jdbc drivers...

anyway, it works right now Smile

Hi,

thanks for the update. A required reboot would be new to me, but I'm glad it works now, whatever the reason Smile

Hi,

We are experiencing the same problem as stated. GUIDancer was working ok, I experienced a problem connecting to my remote client (which I have received on and off). This caused me to reboot the GUIDancer client. On restarting GUIDancer I received the same message, I am left with a database login prompt requesting me to enter a valid username and password and the specified connection being the 'Default Embedded (H2)'. Clicking OK on the prompt only repeats the problem.

I have rebooted both machines and there is still the same problem.

Any thoughts gratefully received,
James.

Hi,

There may be a lock on the H2 database - it sounds like something I've seen once or twice. Unfortunately, I'm not a database expert, so I wouldn't want to recommend how to get rid of the lock, but maybe this information helps you further.

Best regards,
Alex
