Sorry I am newbie to Hibernate !!

You just have to be a little more verbose!

Are you asking when to implement Serializable in you POJOs?
In that case the answer is: when you want to use them in some kind of webapp or send them over network. Hibernate per se does not require the POJOs to be Serializable, I think.

/C

So do u think Hibernate need POJO to be implemented Serialize?

Hibernate does not require POJOs to implement Serializable. If for example you put the POJOs in HTTPSession or send them over the network then they need to serializable.
