All Implemented Interfaces:

Serializable

public class ObjectNotFoundException

extends FinderException

The ObjectNotFoundException exception is thrown by a finder method to indicate that the specified EJB object does not exist. ObjectNotFoundException异常由finder方法抛出，表示指定的EJB对象不存在。

Only the finder methods that are declared to return a single EJB object use this exception. This exception should not be thrown by finder methods that return a collection of EJB objects (they should return an empty collection instead). 只有当finder方法声明返回单个EJB对象时才使用该异常。如果finder方法 返回EJB对象的集合，则不会抛出该异常，而是返回一个空的集合。
