急成马了！！！

Question

当然是报错了，因为request没有定义啊用servlet一般要重写doGet(HttpServletRequest request,HttpServletResponse response) 或doPost(HttpservletRequest request,HttpServletResponse response)
然后服务器会根据具体的情况调用相应的方法。你的意思的可能是以下的。
public class FormRequest extends HttpServlet {
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws IOException,ServletException
{
doPost(request,response);
}
public void doPost(HttpServletRequest request,HttpServletResponse response)
throws IOException,ServletException
{
NewsVo var=addrequest(request);}    
public NewsVo addrequest(HttpServletRequest request) {
        WYTools tool = new WYTools();
        NewsVo news = new NewsVo();
        String title = (String) tool.nvlStr((request.getParameter("title")));
        String titlecolor = (String) tool.nvlStr((request.getParameter(
                "titlecolor")));
        String content = (String) tool.nvlStr((request.getParameter("content")));        news.setContent(content);
        news.setTitle(title);
        news.setTitlecolor(titlecolor);
        return news;
    }
