Question

我有一个名为index.html的文件，它直接放在WebContent内，所有脚本文件也在正确的位置。

servlet看起来像这样：

public class CreateService extends HttpServlet {
   private static final long serialVersionUID = 1L;

   public CreateService() {
      super();
   }

   protected void doGet(HttpServletRequest request, HttpServletResponse response)
      throws ServletException, IOException {
         doPost(request,response);
   }

   //calling html file instead of jsp 
   protected void doPost(HttpServletRequest request, HttpServletResponse response) 
      throws ServletException, IOException {

         String gisuniqkey=request.getParameter("gisuniqkey");
         RequestDispatcher reqDispatcher = 
             getServletConfig().getServletContext()
                .getRequestDispatcher("/index.html");
         reqDispatcher.forward(request,response);       
   }
}

当我尝试在服务器中加载url时，说找不到资源。这是我得到的错误：

文件夹结构如下所示：

.:
assets               images        META-INF             test.jsp
CreateScenario.jsp   index.html    ms.jsp               UpdateScenario.jsp
cs.jsp               index.jsp     multipleDisplay.jsp  WEB-INF
css                  js            objtype.json
DisplayScenario.jsp  JsonData      Scenario.json
EditScenario.jsp     jsonscenario  scripts

./scripts:
gmaps_createScenario.js  gmaps_drawPolygon.js  info.js  maploader.js
gmaps_drawLine.js        gmaps_events.js       lib
gmaps_drawMarker.js      gmaps.js              main.js

./scripts/lib:
backbone.min.js  jquery.min.js  plugins  require.js  underscore.min.js

./scripts/lib/plugins:
async.js   font.js  image.js  mdown.js  propertyParser.js
depend.js  goog.js  json.js   noext.js

这是web.xml file in a pastebin

这是MainService，我相信这会重定向到CreateService：

 RequestDispatcher reqDispatcher = getServletConfig().getServletContext().getRequestDispatcher("/CreateService");
        reqDispatcher.forward(request,response);

当我尝试调用url时，会抛出以下错误：

 Server Tomcat v7.0 Server at localhost was unable to start within 45 seconds. If the    
 server requires more time, try increasing the timeout in the server editor.

因此，您要拨打http://localhost:8180/GisProject/MainService?，根据您的MainService调用web.xml课程。不过，您在此处显示的是CreateService，如果您拨打http://localhost:8180/GisProject/CreateService，系统会调用该index.html。

如果你想要的是在调用http://localhost:8180/GisProject/MainService时显示MainService，那么你必须将实现移到{{1}}类。

从Servlet调用html文件
