I have a JSP page where I have a hyperlink to view a file. The file could be a word doc, or a pdf doc. If the user clicks on the link the document is opened in the browser. Is there a way to open it outside the browser by launching the corresponding viewer. The browser view should remain the same as it was befoore the link was clicked.

here is the simple JSP (only posting the relevant code)

   <a href="Popup">Click here to download</a>

The servlet that writes the file


public class Popup extends HttpServlet {

    public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException   {

            String fileName ="XMLAppuserguide.pdf";
        response.setContentType("application/pdf");
       
            ServletOutputStream sos = null;
        sos = response.getOutputStream();
       
            File file = new File(fileName);
            System.out.println("-----------------"+file.getAbsolutePath());
            FileInputStream fis = new FileInputStream(file);

       
            int  b = fis.read();
        while (b!=-1) {
           sos.write(b);
           b=fis.read();
        }
    }
}

I need to do it through a servet, since there is some other logic in servlet that I have not posted.

And if you want to open and reuse one single popup window on every link klick, then give the popup window a Name:

<a href="Popup" target="myPop" >Click here to download</a>

<<<a href="Popup" target="_blank" >Click here to download</a>

But this still opens it in the browser. I want the application to be launched directly.

To be more precise with what I posted above, there'll be only .tiff images that need to be opened in the microsoft image viewer. There are no pdf and msword files, I posted that just as an example.

When I give the path to .tif image in my servlet, then I get an open/save dialog box. Is there a way to compress this dialog box, so that the image directly opens in the viewer.

response.setContentType("application/octet-stream");

Try a download servlet like this:

well as everybody above has said.. you will have to set the contnet type of your response data depending upon what kind of data you are sending to the client.

for example for a MS-word file you will have to do

response.setContentType("application/msword");
for a gif image it has to be..

response.setContentType("image/gif");

and so on..

you will have to cover a lot of mime types to have it all covered.

Did you try:

            String fileName ="myImage.tif";
        response.setContentType("image/tiff");
