在发布ejb项目成jar文件时报如下错：

提示我的主要错误是：You have not defined a jta-data-source for a JTA enabled persistence context named: DefaultDS

但是我已经定义了。。。啊。。

如果没有persistence.xml文件时，即不用entitybean时没问题，
加上了这个文件与数据源打交道时就出错了/。。。
哪位高手帮帮忙看看 了。。

需要配置一个名为DefaultDS的数据源，数据源的配置方式很简单，就是将docs/
examples/jca目录下数据库服务器-ds.xml文件拷贝到default/deploy目录下，修改其中的连接参数就可以了

[沫亦轩]

不是啊，，已经配置好数据源了。
出现上面的问题啊。。
怎么回事啊。。

[JBossWeek]

lz把persistence.xml文件贴一下，应该是配置的问题
