在jsp上显示pdf||网页直接打开PDF 在IE中显示pdf文档的方法及参数设置
一:在jsp上显示pdf   Java代码 
 
<%@ page language="java" import="java.util.*,java.io.*" 
pageEncoding="ISO-8859-1"%>  
<%  
String path = request.getContextPath();  
String basePath = request.getScheme() + "://" 
    + request.getServerName() + ":" + request.getServerPort()  
    + path + "/";  
%>  
 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

   <base href="<%=basePath%>">

<%  
   out.clear();  
   out = pageContext.pushBody();  
   response.setContentType("application/pdf");  
 
   try {  
    String strPdfPath = new String("D://200701010001.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());  
   }  
%>

    + request.getServerName() + ":" + request.getServerPort()

       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());
   }
%>

二: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,结果可行。
代码如下:

三: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)

IE7.0以上版本的浏览器中可用如下方法,低版本的IE会显示两个Object区域
