我用servlet返回结果的

不错,这个答案还过得去,就是写了很多不知道的东西,不过还算看得懂,最后问一下,那个httpServletResponse.getWriter().write(content);
改成httpServletResponse.getWriter().println(content);
行不行啊

不知道为什么我的Servlet这么写结果老是说xml只能为一个根元素
String result = "<?xml version=\"1.0\" encoding=\"gb2312\"?>\n";
    result += "<people>";
    while(rs.next()) {
        result += "<person>";
        result += "<NO>" + rs.getString(1) + "</NO>\n";
        result += "<NAME>" + rs.getString(2) + "</NAME>\n";
        result  += "</person>";
    }
    result += "</people>";
    out.println(result);
    out.write(result) ;
