部署BMP的问题

[jeoky]

部署BMP时总是报错.

Warning: The class must be defined as public and must not be abstract.

警告说你的bean中没有ejbFindByPrimaryKey 这个方法？？
加上就可以了！

[wangwd]

实体Bean必须声明为public，这是为了容器生成bean的实例，
第二，实体bean与会话bean的区别是比较明显的，它必须有一个ejbFindByPrimaryKey方法，这是用来查找表的主键，实体bean必须根据这些主键进行相关的操作

我已经定义ejbFindByPrimaryKey方法了，还是报错.
