compoistePK class and Serializable

[Charu Sama]

One simple question - Why compositePK class needs to implement Serializale interface?

[Paul Sturrock]

Is this a question about Hibernate?

[Charu Sama]

Yes, but even CMP/JPA also need this if I am correct.
But, this is specific to Hibernet.

[Charu Sama]

Any idea ??

[Mark Spritzler]

Same reason as why any Mapped object will need to be Serializable if you want to transport the object to the client or something in a different JVM.
