What should be the content type to download any file format in jsp?

java, jsp

Solution

Finally I somehow managed to do this... The problem is with JSP's "Out.write", which is not capable of writing byte stream...

I replaced jsp file with servlet...

The code snippet is:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    try {
        String filename = (String) request.getAttribute("fileName");
        response.setContentType("application/octet-stream");
        response.setHeader("Content-Disposition",
                "attachment;filename="+filename);

        File file = new File(filename);
        FileInputStream fileIn = new FileInputStream(file);
        ServletOutputStream out = response.getOutputStream();

        byte[] outputByte = new byte[(int)file.length()];
        //copy binary contect to output stream
        while(fileIn.read(outputByte, 0, (int)file.length()) != -1)
        {
        out.write(outputByte, 0, (int)file.length());
        }
     }

Now I can download all types of files....

Thanks for the responces :)

Problem

I want to make a provision to download all file types...Is there any way to download any file format in jsp... My code snippet: ``` String filename = (String) request.getAttribute("fileName"); response.setContentType("APPLICATION/OCTET-STREAM"); String disHeader = "Attachment"; response.setHeader("Content-Disposition", disHeader); // transfer the file byte-by-byte to the response object File fileToDownload = new File(filename); response.setContentLength((int) fileToDownload.length()); FileInputStream fileInputStream = new FileInputStream(fileToDownload); int i = 0; while ((i = fileInputStream.read()) != -1) { out.write(i); } fileInputStream.close(); ``` If I specify setContentType as APPLICATION/OCTET-STREAM, pdf, text, doc files are getting downloaded.... But the problem is with image files... What is problem with image files? I want to download all image file types... I searched similar questions but could not find proper answer... Thanks...
