jWebapp MVC 框架

jWebApp是一个基于Servlet的MVC框架，目的是为了简化小型web项目的开发复杂度。

示例：

jWebAppisliterallythissimple:

   publicclassHelloWorldextendsRequestHandler{

       publicStringprocessHello(ServerInterfaceserverInterface){

           serverInterface.setAttribute("helloWorld","HelloWorld");

           return"/WEB-INF/helloWorld.jsp";

         }

       publicStringprocessHelloAgain(ServerInterfaceserverInterface){

           serverInterface.setAttribute("helloWorld","HelloWorldAgain");

           return"/WEB-INF/helloWorld.jsp";

         }

     }
