The purpose of the Windchill ESI EAI Windchill Simulation module is to give an end-user a mechanism for simulating the Windchill Enterprise Systems Integration services within TIBCO BusinessWorks. This simulation module enables users to verify the EAI software components without the need for the Windchill Open API. This module also provides a tool for debugging issues that arise during development, QA testing, and technical support by minimizing the number of possible contributing factors to the issue. It is expected that implementation teams will leverage the module to verify customizations that have been done to the EAI software components and/or Windchill independent of a Windchill environment. The subsequent pages of this document provide an overview of the Windchill ESI EAI Windchill Simulation module as well as instructions and examples for using the module.
