javax.ejb
Class DuplicateKeyException

All Implemented Interfaces:

Serializable

public class DuplicateKeyException extends CreateException

The DuplicateKeyException exception is thrown if an entity EJB object cannot be created because an object with the same key already exists. This exception is thrown by the create methods defined in an entity Bean's home interface. 如果实体EJB对象因为要创建的EJB对象与现有的对象key相同而失败，则抛出DuplicateKeyException 异常。该异常由实体Bean home接口定义的create方法抛出。
