private void pd4mlToPdf(String htmlCode, HttpServletResponse response,
    String str) {
    
    
    try {
    String date = StringUtil.getstrFdate(new Date(), "yyyy-MM-dd");
    String title = str + date;
    OutputStream out = response.getOutputStream();
    response.setHeader("Content-disposition", "attachment; filename="
    + new String(title.getBytes("gbk"), "iso8859-1") + ".pdf");
    response.setContentType("application/download");
    StringBuffer html = new StringBuffer();
    // 组装成符合W3C标准的html文件
    html.append("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">");
    html.append("<html xmlns=\"http://www.w3.org/1999/xhtml\">")
    .append("<head>")
    .append("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" />")
    .append("<style type=\"text/css\" mce_bogus=\"1\">*{font-family: SongTi_GB2312;}</style>")
    .append("<style type=\"text/css\">img {width: 700px;}</style>")
    .append("</head>").append("<body>")
    .append(htmlCode);
    html.append("</body></html>");
    org.jsoup.nodes.Document doc = Jsoup.parse(html.toString());
    Element el = doc.getElementById("ordertitle");
    el.removeAttr("style");
    el.attr("style", " FONT-SIZE: 33px");
    // System.out.println(doc.toString());
    StringReader sr = new StringReader(doc.toString());
    PD4ML pd4ml = new PD4ML();  
           pd4ml.setPageInsets(new Insets(20, 10, 10, 10));  
    //        pd4ml.setHtmlWidth(950);  
    //        pd4ml.setPageSize(pd4ml.changePageOrientation(PD4Constants.A4));  
           pd4ml.setPageSize(PD4Constants.A4);
           pd4ml.useTTF("java:com/wansin/contract/fonts", true);  
    //        pd4ml.setDefaultTTFs("KaiTi_GB2312", "KaiTi_GB2312", "KaiTi_GB2312");  
           pd4ml.enableDebugInfo(); 
           pd4ml.render(sr, out);
    out.flush();
    out.close();
    
    } catch (ExceptionConverter e1) {
    System.out.println("ie 关闭连接");
    } catch (Exception e) {
    e.printStackTrace();
    }
    
    }

用到的相关jar包  pd4ml\_demo.jar     ss\_css2.jar   jsoup-1.6.1.jar

中文字体问题   需要字体文件 SONGTI.TTF 和配置文件 pd4fonts.properties

文件内容为

KaiTi\_GB2312=SIMKAI.TTF  
SongTi\_GB2312=SONGTI.TTF

配置文件的读取 跟.append("<style type=\\"text/css\\" mce\_bogus=\\"1\\">\*\{font-family: SongTi\_GB2312;\}</style>")这个有关 所以要想引用字体  pd4ml.useTTF("java:com/wansin/contract/fonts", true); 就得在html中加入字体配置 com/wansin/contract/fonts为字体文件及配置文件的包名
