Hello World!
With these basic project structure, portlet.xml and web.xml in place, it's time to do the mandatory "Hello World" example, so let's create a place to store our JSP files. Create a WEB-INF/pages/view folder, and within this folder, create the file "helloWorld.jsp". In this file, we simply put:

xwork.xml
At this point, it's time to prepare the xwork configuration file, xwork.xml. Create an empty file named xwork.xml in the root of the 'src' folder. In this file we put:

Next, let's do something a bit more interesting, namely create a simple form and display a result page. Let's start by creating our JSP that displays our form. Create a new file, 'helloForm.jsp' in the WEB-INF/pages/view/ folder. We will use the WebWork tag library to build the form on our page. The form itself will ask the user for a first name and last name, something like this:
鎺ョ潃, 鎴戜滑鏉ュ仛涓浜涙湁瓚ｇ殑浜? 涔熷氨鏄垱寤轟竴涓畝鍗曠殑 form 騫舵樉紺轟竴涓粨鏋滈〉闈? 鎴戜滑鍏堟潵鍒涘緩涓涓?JSP 欏甸潰鏉ユ樉紺鴻繖涓?form. 鍒涘緩涓涓柊鐨勬枃浠?'helloForm.jsp', 鏀懼湪 WEB-INF/pages/view/ 鐩綍涓? 鎴戜滑灝嗕細(xì)浣跨敤 WebWork 鏍囩搴撳湪鎴戜滑鐨勯〉闈笂鍒涘緩榪欎釜 form. 榪欎釜 form 浼?xì)璇㈤棶鐢ㄦ堬L(fēng)殑鍚嶅瓧鍜屽, 灝卞儚榪欐牱:

We also need a JSP to display the processed input. We'll just use the old helloWorld.jsp and modify it a bit. As with helloForm.jsp, we import the WebWork tag library, and we use the ww:property tags to display the input from the form:
鎴戜滑榪橀渶瑕佷竴涓?JSP 鏉ユ樉紺?input 鐨勫鐞嗙粨鏋? 鎴戜滑榪樹(shù)嬌鐢?helloWorld.jsp 鐒跺悗淇敼涓涓? 涓?helloForm.jsp 涓鏍? 鎴戜滑寮曞叆 WebWork 鏍囩搴? 鐒跺悗鎴戜滑浣跨敤 ww:property 鏍囩鏉ユ樉紺?form 涓緭鍏ョ殑鍐呭:
