[jboss-user] [JBoss Seam] - JBoss 4.2.1GA and Hibernate validator - broken

The following is not a Seam issue, even though it may be important to Seam users. Bug description: ========== JBoss AS 4.2.1GA is shipped with Hibernate Core 3.2.4.sp1 Hibernate Annotations 3.2.1.GA Hibernate EntityManager 3.2.1.GA The problem is that instantiation of a Hibernate Validator specified with the org.hibernate.validator.Min annotation fails with an exception (see below). How to reproduce the bug: =================== Use JBossAS4.2.1GA and the Seam hotel booking example and annotate method getPrice() of org.jboss.seam.example.booking.Hotel with @Min(0). Then deployment of the hotel booking application fails. | 2007-08-06 06:13:45,540 DEBUG [org.jboss.ejb3.ServiceDelegateWrapper] Starting failed persistence.units:ear=jboss-seam-booking.ear,jar=jboss-seam-booking.jar,unitName=bookingDatabase | java.lang.IllegalArgumentException: could not instantiate ClassValidator | at org.hibernate.validator.ClassValidator.createValidator(ClassValidator.java:294) | at org.hibernate.validator.ClassValidator.createMemberValidator(ClassValidator.java:262) | at org.hibernate.validator.ClassValidator.initValidator(ClassValidator.java:215) | at org.hibernate.validator.ClassValidator.<init>(ClassValidator.java:134) | at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:318) | at org.hibernate.cfg.Configuration.buildMappings(Configuration.java:1115) | at org.hibernate.ejb.Ejb3Configuration.buildMappings(Ejb3Configuration.java:1233) | | ... | Question: ======= What needs to be done in order to successfully use the org.hibernate.validator.Min validator? Could a solution be the replacement of the Hibernate packages shipped with JBoss AS 4.2.1GA with more recent versions? I tried to replace those Hibernate jars with Hibernate core 3.3.0GA, Hibernate EntityManager 3.3.1.GA, Hibernate Annotations 3.3.0GA and Hibernate Validator 3.0.0GA, but this produces a a classloading error when Hibernate is started up. Are there any instructions out there how JBossAS needs to be configured when using the latest Hibernate versions?
