I am new to servlets. I want to render a word document from a servlet.

There is a JSP page

<HTML>
<BODY>
  <a href="Sample">Download</a>
</BODY>
</HTML>

When user clicks on this link, a servlet is called

public class Sample extends HttpServlet {


    public void doGet(HttpServletRequest request,
                      HttpServletResponse response)
        throws IOException, ServletException   {
        String file ="myWord.doc";
        response.setContentType("text/html");
       
            ServletOutputStream loStr = null;
        loStr = response.getOutputStream();
        loStr.write(file.getBytes());
        loStr.flush();
        loStr.close();
       
    }
}

This servlet has to read a word document from the web server file system and download it on user's machine. But what I have written above only prints "myWord.doc" on the browser and does not download the file.
Please help

loStr = response.getOutputStream();
        loStr.write(file.getBytes());
here you have taken the bytes of the string "file" and printed it out...
obviously it will print just the name of the file..

you need to do following..
String file = :myWord.doc";
File f = new File(file);
FileInputStream fin = new FileInputStream(f);
int byte b = fin.read();
while (b!=-1)
{
loStr.write(b);
b=fin.read();
}


also
response.setContentType("text/html");

should be
response.setContentType("application/msword");
for it to display the doc correctly.
