11.3. Serialization of JDO instances
J2EE components communicate with their clients (actual clients or other J2EE components) using RMI. To improve interoperability, most application servers channel their RMI calls over the IIOP protocol. RMI facilitates the passing of objects by value through serialization. This technique is widely employed by middle-tier Java designers, and is likely to be applied to persistence-capable objects. This section examines the serialization of persistent instances.
The serialization process can be invoked explicitly on any object implementing the Serializable interface. However, it is more common for it to occur implicitly, as happens whenever a Serializable object is included as an argument to or return value from ...
