_NET和J2EE该相互学习什么 Application的Framework竟然达到了55个，并且还在日益增加。事实上J2EE开发的软肋不在于Control这个层面，而是在View。许多天才的精力都耗在重复制造轮子上，却没有想办法去完善一个或者多个Framework，这不得不让人感到痛心啊！在这一点，J2EE是不是得向.NET好好学习一下呢？在.NET的世界里，最受关注的应该是控件的开发了，一个设计良好，功能强大的控件对于提高开发效率无疑是极好的助推器。很多.NET的开发人员都将精力花在设计控件上，.NET就像一个聚宝盆一样，不断汇聚开发人员智慧结晶。在J2EE的世界里，为了减少这种资源浪费的情况，Wicket Framework的出现了。它强调组件设计和组件重用，让开发人员集中精力于组件的开发，从而增强Framework的功能已经易用性。但愿，Wicket -Garage and the J2EE Application learn from each other what the Framework has reached 55 and is still growing. In fact J2EE development weakness lies not in the level of Control, but the View. Many are gifted energy consumption in duplicate on wheels, but did not try to perfect one or more Framework, which compelled people to feel sad ah! At this point, is not a J2EE to.NET can learn from it? In.NET world, the most concern is the development of the controls, a well-designed, powerful controls for the improvement of development efficiency is undoubtedly an excellent booster. A lot.NET developers will b
