ejava.examples.daoex.dao.DAOException

All Implemented Interfaces:

Serializable

public class DAOException
extends RuntimeException

This is the base exception for example DAOs. Note the design decision that needs to be made between a checked Exception and an unchecked RuntimeException. By using checked Exceptions you are requiring all interfacing code to deal with the exception -- even if it cannot correct it. By using unchecked RuntimeExceptions the interfacing business code can be written cleaner by not being polluted with infrastructure exceptions.
