关于实体类间的seqence生成器名称（name)重复问题

micro2000 2010-11-28 12:32:49

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？
