在entityBean中,如何将ejbstore方法中的错误抛出给客户段啊??

小弟用sessionBean,更新数据,J2EE容器自动调用EJBSTORE()方法,但是这里很有可能会出错,比如数据类型,插入的值对于列过大等SQLerror,这些错误都必须传给客户段的错误,高手们是怎么作的啊??

Client can get message using RemoteException.getMessage();

Ejb container can only throw ejbexception which is remoteexception.you have to wrap your specific exception(sql exception) passed and rethrow ejbexception.

This is the basic question on ejb.
