jasper 生成 PDF 代码

ArrayList<UserInfo> arrayList=new ArrayList<UserInfo>();
    UserInfo userInfo;
    for(int i=0;i<100;i++){
      userInfo=new UserInfo();
      userInfo.setName("name"+"00"+i);
      userInfo.setAge(i);
      arrayList.add(userInfo);
    }
    String jrxmlName="ceShi";
    String fileName= request.getSession().getServletContext().getRealPath("")+"/WEB-INF/reports/" + jrxmlName + ".jasper";
    JRBeanCollectionDataSource jr = new JRBeanCollectionDataSource(arrayList);
    Hashtable<String, Object> parameters=new Hashtable<String, Object>();
    parameters.put("time", "20090808");
    JasperPrint print;
    try {
      print = JasperFillManager.fillReport(fileName,parameters,jr);
      String pdfFullPath="D://あああ.pdf";
      JasperExportManager.exportReportToPdfFile(print,pdfFullPath);
    } catch (JRException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }

此代码为在服务器上生成PDF，可以再写个下载PDF的代码片段 ，如下：

response.setContentType("application/octet-stream;charset=shift_jis");
    response.setHeader("Content-Disposition", "attachment; filename=/""
        + new String(pdfFullPath.getBytes(), "iso-8859-1") + "/"");
    InputStream in = new FileInputStream(new File("D://あああ.pdf"));
    OutputStream out = response.getOutputStream();
    byte[] buffer = new byte[1024];
    int i = -1;
    while ((i = in.read(buffer)) != -1) {
      out.write(buffer, 0, i);
    }
    out.flush();
    in.close();
    out.close();
    out=null;
    in=null;
