jsp调用ireport进行客户端打印

前提:客户端需要安装jdk,服务段需要有相关的jar包,itext包等。。。

jsp:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<head>
<title>打印</title>
</head>
<body scroll="no" style="overflow: hidden;">
<object 
      classid = "clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" 
      codebase = "http://java.sun.com/update/1.6.0/jinstall-6u13-windows-i586.cab#Version=6,0,0,3" 
      WIDTH = "100%" HEIGHT = "100%" >
      <PARAM NAME = CODE VALUE = "EmbeddedViewerApplet.class" >
      <PARAM NAME = CODEBASE VALUE = "../../applets" >
      <PARAM NAME = ARCHIVE VALUE = "jasperreports-3.5.3-applet.jar,commons-logging-1.0.2.jar,commons-collections-2.1.jar" >
      <param name = "type" value = "application/x-java-applet;version=1.6">
      <param name = "scriptable" value = "false">
<!--                请求的servlet路径             -->
      <PARAM NAME = "REPORT_URL" VALUE ="someServlet?someParam">
 
</object>
</body>
</html>
 
servlet核心代码:
String jasperName = session.getServletContext().getRealPath("/report_print/office_template") + File.separator + "jywwdjb_bg2.jasper";
try {
DriverManagerDataSource ds = 。。。;
JasperReport jasperReport = (JasperReport) JRLoader.loadObject(jasperName);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,paramMap,ds.getConnection());
   if (jasperPrint != null)
   {
   response.setContentType("application/octet-stream");
   ServletOutputStream ouputStream = response.getOutputStream();
   ObjectOutputStream oos = new ObjectOutputStream(ouputStream);
   oos.writeObject(jasperPrint);
   oos.flush();
   oos.close();
 
   ouputStream.flush();
   ouputStream.close();
   }
} catch (JRException e) {
e.printStackTrace();
}catch (Exception e) {
e.printStackTrace();
log.error(e.getLocalizedMessage());
}
