Re: redirectig to WORD files

[Erik Weber]

Rather than go into all the details, here is the nuts and bolts of doing 
this from within an Action.

In your Action class' execute implementation, your goal here is not to 
return an ActionForward as you typically do. You need to have a little 
bit lower level control over the HTTP response to serve binary content 
from within a Struts app. So you will set some response headers 
(including the MIME type), transfer the data 1 byte at a time (or one 
buffer at a time) from the local Word file (using a FileInputStream or 
similar) to the response's output stream, close the stream yourself, and 
then return null from your execute method, to let the Struts controller 
know the Action has handled the response on its own and that no 
forwarding will be required (nothing else need be written to the 
stream). This all assumes that the user has been provided a link to the 
file that contains some sort of token your Action can use to find the 
correct file on a protected area of the local filesystem (rather than a 
link directly to a file in your web server public doc root).

MIME type lists can be found on the Web. I think it's something like 
"application/ms-word" but I can't remember. The use is:

response.setContentType("application/ms-word");
or you can use setHeader directly.
Various other response headers (content length, content disposition -- 
which should let you control whether you want a new browser window, 
caching, etc.) probably will be useful to you. Their use can be 
researched on the Web (on this list too but it has been a while) and is 
not particular to Struts.

Hope that helps,
Erik

Hi all I try to redirect my response to a word doc file.But after
setting contexttype and using response.sendRedirect(docWordURL) , I
get white page; What I want is open this word document on a click of a
link in a normal jsp.I call the action that has to redirecting me to
that file. Any idea? Regards
     

Try
       response.setContentType( "whatever_suitable_for_msword" );
       response.setHeader( "Content-Disposition", 
                           "attachment; filename=foo.doc" );

Then write to response.getWriter(). Worked for me.
