It's simple - need add to web.xml next elements:
<web-app>
...
<servlet>
<servlet-name>documents</servlet-name>
<servlet-class>asoft.web.Doc_view</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
...
<servlet-mapping>
<servlet-name>documents</servlet-name>
<url-pattern>/documents/*</url-pattern>
</servlet-mapping>
...
</web-app>

Hi Vladimir,
My code is inside a ActionListener of CommandLink component of JSF and
that may be the reason it is not working. I am not able to figure out
how to forward control to servlet from ActionListener. Can you please
tell me how do you forward control to servlet from your JSF page?

Hi Raj,
I look your code. I think, it does not work because you use not pure
сервлет for loading. I do not see heading of your class - similar that
it Faces PageBean?
I use a combination JSF pages + simple pure Servlet, listening part URL
for download:
public class Doc_view extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
String uri = request.getPathInfo();
int pdoc_id=Integer.parseInt(request.getParameter("doc_id"));
try {
response.setContentType("application/x-download");
response.setHeader("content-disposition", "attachment;
name=\""+downloadFileName+"\"; filename=\""+downloadFileName+"\"");
byte[] data = .... ;
response.setContentLength(data.length);
response.getOutputStream().write(data);
} catch (Exception e) {... }
}

Hi Vladmir,
I tried your suggestion. It did not work for me. I am using apche my
faces JSF bridge. Does it work for you form a JSF based porlet?
Below the the code snipt of processAction method of command link
action listener. Can you see if I am missing something?
============================
FacesContext facesContext = FacesContext.getCurrentInstance();
String path =
facesContext.getExternalContext().getInitParameter("uploadDirectoryLocation");
Map map =
facesContext.getExternalContext().getRequestParameterMap();
String fileName = (String) map.get("fileName");
System.out.println("File URI: " + path+fileName);
File file = new File(path + fileName);
long fileSize =file.length();
//Set the HTTP headers for foce download the file
HttpServletResponse response =
(HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
response.setContentType("application/x-download");
response.setHeader("content-disposition",
"attachment;name=\""+fileName+"\";filename=\""+fileName+"\"");
response.setContentLength((int)fileSize);
==========================================================

Subject: Force downloading a file in JSF portlet
Hi,
I am building JSF based portlet for downloading a file using MyFaces JSF
bridge.
I do the following to make the file force download:
1) Set "content-disposition" header to contain the correct filename
2) Set "content-type" header to "application/octet-stream" or something more
accurate if the information is present in attachment metadata
3) Dump the content using a ServletOutputStream
When I click on the link to download the file, instead of throwing a dialog
box for saving/opening the file, browser dumps the the binary contents on
page. However, this works fine as standalone application.
Is there something extra I need to do to force download file in Jetspeed? Am
I missing something here?
Regards,
Raj
