Thanks for you reply. I think I have fixed my initial problem, there was a problem with the cayenne.xml file. But now I am having trouble with my context.commitChanges() line. I am getting this error:
Exception in thread "main" org.apache.cayenne.CayenneRuntimeException: [v.3.0RC1 Jan 05 2010 14:44:59] Commit Exception at org.apache.cayenne.access.DataContext.flushToParent(DataContext.java:1134) at org.apache.cayenne.access.DataContext.commitChanges(DataContext.java:1045) at org.example.cayenne.persistent.Main.main(Main.java:30) which doesnt make much sense to me except that I understand that commitChanges actually sends the data to the database to be saved. Otherwise I'm lost. -- View this message in context: http://n3.nabble.com/Class-is-not-mapped-tp183513p184666.html Sent from the Cayenne - User mailing list archive at Nabble.com.
