E1: GEN: Frequently Asked Questions on Java Serialized Objects and Generation (Doc ID 1350850.1)

Last updated on FEBRUARY 01, 2019

Applies to:

JD Edwards EnterpriseOne Tools - Version SP24 and later
Information in this document applies to any platform.

Purpose

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.

 Question 6: How to generate serialized objects for EnterpriseOne Xe/ERP8 with Websphere 6.1 or Oracle Application Server 10g?
 Question 7: Can a generation machine be configured with OC4J (Oracle Application Server) and be used to generate serialized objects for a JAS/Web Server that has WebSphere 7 installed?
 Question 8: What is the possibility to use OAS and WebLogic, WebSphere and WebLogic, different WebSphere versions, etc. with the same serialized tables?
