我从数据库中检索一个pdf文件，并将其放入这样的文件中

I retrieve a pdf file from my database and put it in a file like this

String str="select * from files where name='Security.pdf';";
Statement stmt2= conn.createStatement  
                   (ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
rs = stmt2.executeQuery(str);
while(rs.next())
{
 InputStream input = rs.getBinaryStream("content");
 //to create file
   File f=new File("c:/pdfile.pdf");
   OutputStream out=new FileOutputStream(f);
   byte buf[]=new byte[1024];
   int len;
   while((len=input.read(buf))>0)
   out.write(buf,0,len);
   out.close();
   input.close();
    System.out.println("\nFile is created..");
}

现在这是在服务器端.在我的客户端，每当用户单击链接时，说 在我的jsp页面中 a href = pdf(pdf是我的servlet名称)，我应该在客户端的浏览器上显示从数据库检索到的文件.
我该怎么办?

Now this is at server end. In my client side, Whenever user clicks a link say a href=pdf(pdf is my servlet name) in my jsp page, I should display the file retrieved from database on client's Browser.
What should I do?

推荐答案

将响应的内容类型设置为pdf

Set your content-type of the response to pdf

response.setContentType("application/pdf");

然后将pdf内容写入响应对象

Then write the pdf contents into the response object
