我能够将值提交给servlet,并处理它们(业务逻辑),并将结果提交给requestparamter,以便我可以在UI上检索它们.但我坚持这些：

>重定向到同一页面
>并检索请求参数并使用Sightly显示它们.

代码片段：
Servlet的

@SlingServlet(methods = { "POST","GET" },name="com.tti.tticommons.service.servlets.LeadTimeTrendsServlet",paths = { "/services/processFormData" })public class TTICommonServlet extends SlingallMethodsServlet{   ...@OverrIDeprotected voID doPost(SlinghttpServletRequest request,SlinghttpServletResponse response) throws servletexception,IOException {  String result;  try {        Enumeration<String> parameternames = request.getParameternames();        Map<String,String> formParametersMap = new HashMap<String,String>();        while (parameternames.hasMoreElements()) {            paramname = parameternames.nextElement();            paramValue = request.getParameter(paramname);            .......            .......       }       request.setAttribute("result",result);       response.sendRedirect("/content/ttii/en/**posttest.HTML**");    }}

任何人都可以帮助你在posttest.HTML中使用sightly退出上述“结果”.

解决方法 经过大量的研究和几次试验,我终于让代码工作了.我不得不从stackoverflow中的几个答案中获取相关信息.感谢所有作者.在这里发布我的解决方案对其他人有益.

来自webservice的结果表格：

流程

>将表单数据提交给Servlet的POST方法
>在Servlet中,获取用户从请求中输入的值
>进行必要的Web服务调用.得到回复(Json)
>我将response-Json添加为请求的参数
>使用Wrapper,转到必要的页面
>定义WCMUse类以与Sightly一起使用.
>将“请求”分配给Use-class并在那里处理它
>使用从Use-class到UI的指定值
