It's all in the error message. Either your JDBC driver is buggy and doesn't correctly report primary keys, or your database tables are defined without primary keys. Perhaps they are views? (although from the names they look like tables). JDBC will - AFAIK, never verifed it myself - report views as tables. -And views don't have primary keys.
There is an FR about this here: http://tinyurl.com/29xs So how could you debug this? You can turn on logging by setting the debug level for various classes to debug in middlegen/samples/log4j.properties. If you are working in "your own" project, just copy that file, and make sure you pass it to the VM as it is explained in log4j's doumentation. IIRC it's -Dlog4j.configuration=path/to/your/log4j.properties. If you get any closer, pleaselet us know. Maybe Middlegen has entered into an infinite loop somewhere? I mean, does it hang, or exit or... -And I hope you're using gui="true" ;-) HTH, Aslak > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:middlegen-user-admin@;lists.sourceforge.net]On Behalf Of > [EMAIL PROTECTED] > Sent: 29. oktober 2002 00:43 > To: [EMAIL PROTECTED] > Subject: [Middlegen-user] DB2 / Middlegen -> WARNING: The JDBC driver > didn't report any primary key column... > > > I'm trying to get Middlegen to generate entity bean classes from my db2 > database.
