the last posting on this bug that i can find was on 4/5 by starksm, reporting on jboss 2.4.5. i am using jboss 3.0.3 and am having exactly this problem, i.e. in the beforeCompletion callback failure to rollback an oracle update, and failure to throw an exception to the client. does anyone know the status of this bug/fix? thx...hl
