tomcat PrintWriter没有输出

Question

我刚刚通过Netbeans安装了Tomcat并创建了一个新项目。我只是想在屏幕上打印一些文字但只有“Hello World！”显示。我是否需要特定的内容才能在屏幕上显示文字？

编辑：[求助]我不知道问题是什么。我刚刚将我的IDE从Netbeans改为Eclipse，现在一切正常。

系统：Ubunut 16.04 LTS 64Bit

    @WebServlet(name = "MicStreamReciever", urlPatterns = {"/MicStreamReciever"})
public class MicStreamReciever extends HttpServlet {


    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");

        PrintWriter out = response.getWriter();
        out.println("processRequest");
    }
