Overview

When a web service exposes an interface in the form of a WSDL, that interface is assumed to be static from that point on. The published interface for a web service is considered as a service contract, and the methods and inputs to those methods are intended to remain unchanged for the life of that web service. However, over time, it may become necessary to change the behavior or interface of an existing JD Edwards EnterpriseOne web service to provide enhanced processing or to add fields. When you enhance an existing web service, it is very important that you do not change the original methods and interfaces. This chapter provides concepts and procedures for enhancing business services by creating a version of the original business service.
