关于实体类间的seqence生成器名称（name)重复问题

我们的程序的实体类中的seqence生成器的名称都是一样的@SequenceGenerator(name="SEQ_Generator",sequenceName="SEQ_xxxxxxxx",allocationSize=1)就是那个name="SEQ_Generator"。在jboss中没有问题，我在安装了netbeans6.9.1后，就像把程序放到netbeans自带的glassfish3.0.1跑跑看。现在部署的时候遇到问题说，不同实体类之间的@SequenceGenerator的name重复。实体类内的seqence生成器的作用域范围不是本类内吗？严重: Exception while invoking class org.glassfish.persistence.jpa.JPADeployer prepare method
