Yes this is a bug. I am currently building a new version where this and some other problems are fixed. It should be available later today.

I changed the jdbc-settings and added the schema creation (wich derby does automatic) and my uml-repository is running fine on h2.
It feels as fast as derby and the memory-usage apears a bit lower.

Good work,...]]> Wed, 21 Dec 2005 03:26:03 -0500 Wed, 21 Dec 2005 03:26:03 -0500 Wed, 21 Dec 2005 03:26:03 -0500 Dec 21, 2005 na na 0 Problem with Schemas ? http://www.theserverside.com/discussions/thread.tss?thread_id=38150 There is a build in default admin user whith empty name and password
