Question

Open pdf file in browser

Asked by: darkosrb

Hi guys,

I am trying to open pdf file in browser Internet Explorer from the Servlet. Instead of opening in the browser, It always starts Acrobat and opens the file there. I think I am setting all parameters (Content Type, Content Length and Content-Disposition) correctly, but it does not work. This is part of larger application, so I have to use IE.

Can someone help me?

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
	     
	File file = new File("c:\\example.pdf");
	byte[] fileData = new byte[(int)file.length()];
	FileInputStream fis = new FileInputStream(file);
	fis.read(fileData);
		
	response.reset();
        response.setContentType("application/pdf");
        response.setContentLength(fileData.length);
        response.setHeader("Content-Disposition", "inline;filename=example.pdf");
       
        ServletOutputStream outputStream = response.getOutputStream();
        outputStream.write(fileData); 
        outputStream.flush();
        outputStream.close();
}

Hi darkosrb,

  This code should work for u.
You need not to set the response.

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
 
public class PdfServlet extends HttpServlet
{
    static final long serialVersionUID = 0L;
 
	public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
	{
		File file = new File("c:\\test.pdf");
		FileInputStream in = new FileInputStream(file);
		ServletOutputStream out = response.getOutputStream();
 
		byte[] buffer = new byte[1024];
 
		int len = 0;
		while(true)
		{
			len = in.read(buffer);
			if(len < 0)
				break;
			out.write(buffer, 0, len);
		}
		in.close();
	}
 
	public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
	{
		doGet(request, response);
	}
}

// write your pdf to the stream
writePdfToStream(b);
 
response.setContentType("application/pdf");
response.getOutputStream().write(b.toByteArray());
response.getOutputStream().flush();
response.getOutputStream().close();
