jsf开发 Web应用程序的开发与传统的单机程序开发在本质上存在着太多的差异，Web应用程序开发人员至今不可避免的必须处理HTTP的细节，而HTTP无状态的（stateless）本质，与传统应用程序必须维持程序运行过程中的信息有明显的违背，再则Web应用程序面对网站上不同的使用者同时的存取，其执行线程安全问题以及数据验证、转换处理等问题，又是复杂且难以解决的。 另一方面，本质上是静态的HTML与本质上是动态的应用程序又是一项违背，这造成不可避免的，处理网页设计的美术人员与程序设计人员，必须被彼此加入至视图组件中的逻辑互相干扰，即便一些视图呈现逻辑以标签的方式呈现，试图展现对网页设计美术人员的亲切，但它终究必须牵涉到相关的流程逻辑。 有很多方案试着解决种种的困境，而各自的着眼点各不相同，有的从程序设计人员的角度来解决，有的从网页设计人员的角度来解决，各种的框架被提出，所造成的是各种不统一的标签与框架，为了促进产能的集成开发环境（IDE）难以整合这些标签与框架，另一方面，开发人员的学习负担也不断的加重，他们必须一人了解多个角色的工作。(jsf development Web application development with traditional stand-alone program development, in essence there are too many differences, Web application developers staff has inevitably have to deal with the details of HTTP, and HTTP stateless (stateless) the nature of traditional application must maintain significant breaches in the program is running in.
