CDO and H2 compatibility [message #1859353] Thu, 01 June 2023 16:54 Go to next message

Is CDO 4.20.0 compatible with H2 version 2.1.214. I'd like to upgrade the version of H2 I'm using and I'm wondering if anyone is aware of any "gotchas".

Thank you.

Hi Jay,

I haven't followed the evolution of H2 closely, but CDO uses only very basic SQL functionality, so I doubt that you'll run into big trouble. In any case your feedback is welcome, as at one point I may want to test against newer H2 versions, too ;-)

My effort to use version 2.x of the H2 database is running into the issue described in this tread: https://www.eclipse.org/forums/index.php?t=msg&th=1084110&goto=1753188&#msg_1753188

I'm getting a ClassNotFoundException as described in the thread.

Do you know if this issue was ever resolved? I can't find a resolution other than a workaround described in bugzilla 414834, which I would prefer not to do.

Thank you,
Jay

Hi

All sorts of config problems can lead to a puzzling ClassNotFoundException but ultimately ClassNotFoundException means Class Not Found, so try a much simpler usage. Initially an almost Hello World program using the same MANIFEST and then a couple of extra initialization lines in your actual application. These simpler usages may help you understand what new requirements accessed code has, or what exports are no longer provided for free, or just how Java has evolved.

Regards

Ed Willink
