public class HTTPAuthGatewayServlet

extends HTTPGatewayServlet

The servlet front end to the Windchill HTTP gateway. It is intended to server as the authenticating counterpart to the HTTPGatewayServlet. Servlet engines that are capable of setting access restrictions on servlets may do so on this servlet, leaving the HTTPGatewayServlet as the none authenticating servlet interface.

It's counter part is the CGI wrapper WTAUTHCGI.EXE. This servlet gathers and loads the HTTP request headers and parameters before instantiating the HTTPRequest and HTTPGateway objects which are passed to a method server for processing.

Description copied from class: HTTPGatewayServlet

Our protected serviceWithoutFilters method gathers and loads the HTTP headers etc. into a Properties structure that is passed to the request object constructor. It then instantiates both HTTPRequest and HTTPGateway objects before calling the method server to process the request.

The intent of this method as opposed to service() is that it this method is the raw servlet service handler without any filter application. It is called by service when filters pass the right request to the end of the filter chain.

Overrides:

serviceWithoutFilters in class HTTPGatewayServlet

Throws:

javax.servlet.ServletException

IOException
