I take a fresh download of Seam 2.2.0.GA installed at /jboss-seam-2.2.0.GA, and a fresh install of JBoss 5.1.0.GA, installed at /Applications/jboss-5.1.0.GA (which is where the Seam examples build to). I then go into /examples/groovybooking, run Ant, and then go into JBoss and run bin\run.bat.
Upon JBoss startup, I get...
15:54:35,187 ERROR [SchemaExport] schema export unsuccessful org.hibernate.JDBCException: Error during import script execution at line 1 ... Caused by: java.sql.SQLException: Violation of unique constraint SYS_PK_49: duplicate value(s) for column(s) $$
...and then I am unable to login to the Booking app (ie. using 'demo'/'demo').
If I copy the 'jboss-seam-groovybooking.war' and 'groovybooking-dev-ds.xml' into a fresh install of JBoss 4.2.3.GA (not 5.1.0.GA), it all works fine.
Can anyone confirm this? Am I doing something stupid? Or are there problems with the examples under JBoss 5.1.0.GA?
