解决JSP中拼装数据为XML出现的 问题

 一、应用背景

JSP取得Servlet中放入request的List，将List中的数据拼装成XML。以下代码在Eclipse的内置浏览器中显示为xml，没有问题。

[java]
/**
* 新闻Servlet
* @author 徐越
*
*/
public class ListServlet extends HttpServlet
{
private static final long serialVe

/**
* 新闻Servlet
* @author 徐越
*
*/
public class ListServlet extends HttpServlet
{
private static final long serialVersionUID = 1L;
private VideoNewsService vs = new VideoNewsServiceImpl();

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

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
List<VideoNews> news = vs.readNews();
request.setAttribute("lstnews", news);
request.getRequestDispatcher("/WEB-INF/pages/news.jsp").forward(request, response);
}
}
