判断WAP1.1和WAP2.0并解析为wml或xhtml

首先通过取得accept
java是 request.getHeader("accept")
.net 是 Request.ServerVariables("HTTP_Accept")



    /**
     * 功能：输出xml为wml1.1(wap1.0)
     * @param doc
     * @param response
     * @throws IOException
     */
    public static void OutPrintWAP11(Document doc, HttpServletResponse response) throws IOException {
        response.setCharacterEncoding("utf-8");
        response.setContentType("text/vnd.wap.wml");
        response.setHeader("Cache-Control", "no-cache, must-revalidate");
        PrintWriter out = response.getWriter();
        OutputFormat format = OutputFormat.createCompactFormat();
        //去掉xml头
        format.setSuppressDeclaration(true);
        format.isPadText();
        format.setEncoding("utf-8");
        XMLWriter writer = new XMLWriter(out, format);
        //加上wml头,保证wap协议访问        
        doc.addDocType("wml", "-//WAPFORUM//DTD WML 1.1//EN", "http://www.wapforum.org/DTD/wml_1.1.xml");    
        writer.write(doc);
        writer.flush();
}
     
   
    /**
     * 功能：输出xml为xhtml(wap2.0)
     * @param doc
     * @param response
     * @throws IOException
     */
    public static void OutPrintWAP20(Document doc, HttpServletResponse response) throws IOException {
        response.setCharacterEncoding("utf-8");
        response.setContentType("application/vnd.wap.xhtml+xml");
        response.setHeader("Cache-Control", "no-cache, must-revalidate");
        PrintWriter out = response.getWriter();
        OutputFormat format = OutputFormat.createCompactFormat();
