public class EJBException

extends RuntimeException

The EJBException exception is thrown by an enterprise Bean instance to its container to report that the invoked business method or callback method could not be completed because of an unexpected error (e.g. the instance failed to open a database connection). EJBException异常由企业Bean实例抛向容器，报告因无法预料的错误而调用业务方法或回调方法不能实现（比如实例打开数据库连接失败）。
