各位老大
我用MYECLIPSE5.5开发了个测试的EJB3.0实体BEAN,发布后,做了个测试类调用,老抛出异常,都郁闷了,实在找不到问题所在,特来求教,以下是异常的节选

------解决方法--------------------------------------------------------
查看一下本地接口中的findById（）方法

你的事务管理有问题？

你的测试类是在调用的SessionBean而你的SessionBean是在调用EntityBean，这个方式调用的是本地调用里面的数据是无法被远程调用出来的，可以在外部写个JavaBean然后在EntityBean中将数据放在这个javabean中，在将javabean放在一个ArrayList或Vector中，在远程返回的时候就返回这个集合就可以了 ,你可以试下
