I am using JDK 1.3 R1 on WinNT 4.0. I compiled the Ozone source 0.4-dev4. I can create a database, start the server, and add users using the Admin tool. If I shutdown the server and then restart it I get a "RunTimeException in DxAbstractCollection: Local class not compatible" error. What's going on? I have to recreate the database before I can restart the server. Ted Foye tedf@exis.net
