Entering the Web Server and Servlet Engine Settings
PTC HTTP Server and Embedded Servlet Engine (based on Tomcat) are the Web server and servlet engine that PTC bundles with its Windchill solutions.
The Web server is the front-end authentication mechanism for your Windchill Web application. The PTC HTTP Server is bundled with Windchill and has an automatic configuration. The servlet engine extends the functionality of the Web server by managing the data transfer between the Windchill application server and the client. The Embedded Servlet Engine is bundled with Windchill and has an automated configuration. For more information about the Web servers and servlet engines, see the software matrices:
