• In either Model 1 or Model 2, the JSP file is identified to the server by a .jsp extension
• The first time a request is made for such a file the .jsp file is compiled into a servlet
• The output from the servlet is standard HTML that the browser interprets and displays as usual
• After compilation, the servlet is stored in memory on the server
• If on subsequent requests the .jsp file has changed, it is recompiled
