InitialContext and Passivation

[Sandeep Prabhakar]

Hey Ranchers,
Will the container be able to restore an instance variable that was previously stored with java.naming.InitialContext after passivation-activation?

Cheers,

[Balaji Anand]

yes

Hey,
Can you explain me how? The InitialContext does not implement the Serializable Interface and the specs mentions only about SessionContext.

Cheers,

Hi,

It is not required for a class to definetly implement java.io.Serializable interface in order to get passivated.

According to the spec it is a container's responsiblity to retain the
state of context during the passivation stage.The container is free to
select any technics.

Hope this answer helps you.

It is responsibility of the Container to restore the following during ejbPassivate / ejbActivate mechanism. Container is free to use any technique : (In case u have not patented them

Ref to home and component interfaces, a ref to session context, jndi, user transaction, resource manager connection factory reference.

Do take a look @ object substitution features of the Java Serialization protocol. This states how to serialize an object even though it does not implement java.io.Serializable.
