How to open file using jsp?

[Rajasekhar Eega]

Hi,

Here is my code to download a file using jsp. Its working. But what i need is just to open the file. No need to show the options of saving. just to open. Please help me, what modifications I have to do here???

Thank you

<%@page import="java.io.*,javax.servlet.*,javax.servlet.http.*" %>

<%
String fileName="I:\\Tomcat 6.0\\Ticket Confirmation.pdf";
File f=new File(fileName);
int length=0;
ServletOutputStream op=response.getOutputStream();
ServletContext context=getServletConfig().getServletContext();
String mimetype=context.getMimeType(fileName);
response.setContentType((mimetype!=null) ? mimetype : "application/octet-stream");
response.setContentLength((int)f.length());
response.setHeader("Content-Disposition","attachment:filename="+fileName);
//complete file downloading using buffering
byte[] bbuf=new byte[1024];
DataInputStream in=new DataInputStream(new FileInputStream(f));

while((in!=null)&&((length=in.read(bbuf))!=-1))
{
	op.write(bbuf,0,length);
}
in.close();
op.flush();
op.close();
%>

While setting the header, replace "attachment" with "inline" so that the browser will try to open the file with default application in your machine.

response.setHeader("Content-Disposition","inline:filename="+fileName); //replaced attachment with inline

You really, really shouldn't be doing any of that in a JSP though. That all belongs in a servlet.

Hi All,

Even using
response.setHeader("Content-Disposition","inline:filename="+fileName);
it showing open/save dialogbox in firefox and its downloading in chrome browser..
Can anyone please help me what changes need to get open the file directly without open/save dialog box.please.

Thanks..

Check the browser settings; there's nothing the web app can do about that.

And do yourself a favor by taking Matthew's advice - using a JSP for this will lead to tears. JSPs are for emitting character data, not for processing data, not for file or DB I/O, and not for handling binary data.
