<dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>3.3.2.GA</version> <!--<version>3.6.0.Final</version>--> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-annotations</artifactId> <version>3.4.0.GA</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>3.1.0.GA</version> </dependency>....<dependency> <groupId>hibernate</groupId> <artifactId>hibernate3</artifactId> <version>3.2.3.GA</version></dependency><!-- Hibernate annotation --><dependency> <groupId>hibernate-annotations</groupId> <artifactId>hibernate-annotations</artifactId> <version>3.3.0.GA</version></dependency><dependency> <groupId>hibernate-commons-annotations</groupId> <artifactId>hibernate-commons-annotations</artifactId> <version>3.0.0.GA</version></dependency>
