- When you access a Web page that uses a JSF application from the client, a request goes to the FacesServlet servlet that exists in the JSF framework. The JSF application starts the processing with the FacesServlet as the starting point, and the JSFCore of the JSF framework processes user-defined classes or pages. The result of the request processing is returned as a response to the client through the FacesServlet.
- When you access a Web page that uses JSTL from the client, the JSTL library executes processes corresponding to the tags used in the Web page. The result of the process is returned as a response to the client.
