Solution: If you see above exception it means hibernate-commons-annotations.jar is missing from your class path. For maven project please add below dependency:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-commons-annotations</artifactId>
    <version>3.0.0.ga</version>
</dependency>

You could also check latest version on maven site here

  • If you are using eclipse project then add hibernate-commons-annotations.jar in your class path.
