Second way might be easier. 第二种方法可能更容易。 The Ext Window (or it's parent Panel) component has contentEl property that can be specified. Ext Window（或其父面板）组件具有可以指定的contentEl属性。 What this does is load the html of the element into the Panel component as html property. 这是将元素的html作为html属性加载到Panel组件中。 So you can take an existing JSP with all of its rendered html on the server side and show it as is inside a Window panel. 因此，您可以将现有的JSP及其所有呈现的html放在服务器端，并在“窗口”面板中按原样显示。
The first way might be achieved through a component loader . 第一种方法可以通过组件加载器来实现。 What this does is lets you load content of a remote page (JSP in your case) into your Ext component. 它的作用是让您将远程页面的内容（在您的情况下为JSP）加载到Ext组件中。 I have not used this so I am not sure what limitations you might face with this. 我没有使用过它，所以我不确定您可能会遇到什么限制。 There are however some interesting possibilities described in the docs: http://docs.sencha.com/ext-js/4-1/#!/api/Ext.ComponentLoader 但是，文档中描述了一些有趣的可能性： http : //docs.sencha.com/ext-js/4-1/#!/api/Ext.ComponentLoader
