在jsp页面上直接打开PDF文件

1、在不需要使用插件，直接打开通过链接方式打开

<%@ page language="java" import="java.util.*,java.io.*"pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme() + "://"+ request.getServerName() + ":" + request.getServerPort()+ path + "/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><base href="<%=basePath%>"></head><%out.clear();out = pageContext.pushBody();response.setContentType("application/pdf");try {String strPdfPath = new String("D://01010001.PDF");//判断该路径下的文件是否存在File file = new File(strPdfPath);if (file.exists()) {DataOutputStream temps = new DataOutputStream(response.getOutputStream());DataInputStream in = new DataInputStream(new FileInputStream(strPdfPath));byte[] b = new byte[2048];while ((in.read(b)) != -1) {temps.write(b);temps.flush();}in.close();temps.close();} else {out.print(strPdfPath + " 文件不存在!");}} catch (Exception e) {out.println(e.getMessage());}%><body><br></body></html>

2、如果访问者的计算机上没有装acrobat reader,直接用iframe或者直接用链接打开,那就不是打开文档，而是直接下载了，为了防止下载，想像到媒体文件的播放方式，加上一些官方的docs,考虑用用object标签使用pdf插件嵌入ie中

<HTML><HEAD><META http-equiv="Content-Type" content="text/html; charset=gb2312"><META http-equiv="Content-Style-Type" content="text/css"><META http-equiv="Content-Script-Type" content="text/javascript"><TITLE>Checking if Acrobat Reader installed (IE4+)...</TITLE><SCRIPT for="window" event="onload"</SCRIPT></HEAD><BODY><NOSCRIPT>Cannot determine if you have Acrobat Reader (or the full Acrobat)installed <FONT size="-1">(because JavaScript is unavailable or turned off)</FONT>.</NOSCRIPT><DIV id="IfNoAcrobat" style="display:none"><a href="/cn/reader/">你需要先安装Adobe Reader才能正常浏览文件，请点击这里下载Adobe Reader.</a> </DIV><OBJECT type="application/pdf" width=0 height=0 style="display:none"><DIV id="PDFNotKnown" style="display:none"> </DIV></OBJECT><DIV id=showdivstyle="Z-INDEX: 0; LEFT:10px; WIDTH: 990px; POSITION: absolute; TOP: -8px; HEIGHT: 10px"><object classid="clsid:CA8A9780-280D-11CF-A24D-444553540000" width="990" height="700" border="0" top="-10" name="pdf"> <param name="toolbar" value="false"><param name="_Version" value="65539"><param name="_ExtentX" value="8"><param name="_ExtentY" value="10866"><param name="_StockProps" value="0"><param name="SRC" value="MXL.pdf"></object></DIV></BODY></HTML>

3、在网页中直接显示pdf格式的文件方便阅读。但是如果文件较大加载速度会很慢，另外如果客户端没有安装pdf阅读插件的话，也就看不了了，不过还是贴出来了，各取所需吗。（1.pdf要改成自己的pdf文件路径插入到页面文件中）
