Information in this document applies to any platform.


This document provides answers to some frequently asked questions on Java Serialized Objects and Generation of E1 objects.

Generation: This is where specs are read from the database and they are converted into Java Objects (not code). These objects are in memory.

Serialization: Then these objects are transformed into a binary blob that can be stored in a database. This process is called serialization, and it allows the same JDK to later read this binary data from the database and re-construct the same Java object in memory again.
