The Windchill ESI EAI Windchill Simulation module is designed to simulate the Windchill Open API. It includes all JMS communication between Windchill and the EAI software components solution. It does not include validation of data or messages coming from Windchill or dynamic generation of Windchill responses to EAI software components requests. The Windchill Open API and the communication with the EAI software components solution is comprised of JMS message communication. The Windchill Open API utilizes services within Windchill to extract object information from the Windchill database. Once this information is extracted, the Windchill Open API formats the data into XML so that it may be transported over JMS. The data is dropped onto a JMS queue by the Windchill Open API and is picked up and read by the EAI software components solution enabled in TIBCO BusinessWorks. The opposite also occurs when the EAI Software Components solution places requests or updates to data on JMS queues for the Windchill Open API.

The Windchill ESI EAI Windchill Simulation module provides a mechanism to facilitate the two-way communication between the Windchill Open API and the EAI software components. The module emulates the sending and receipt of JMS messages by Windchill via the Windchill Open API. The module invokes the EAI software components to perform the standard operations as defined by the Windchill Enterprise Systems Integration User’s Guide.
