Amigo,

Este erro ocorre quando está faltando algum jar no seu classpath. No caso desta classe específica está faltando o jar hibernate-annotations.jar.

Baixe o arquivo: hibernate-annotations-3.3.0.GA.zip no site do Hibernate, extraia o hibernate-annotations.jar e adicione-o ao seu classpath.

Abraços.
