Opening a document

I want to stream a document to a user.  I assume I have to create a service 
do to this.  Anyone have some pointers to how this is done?

Workbench has a demo that streams a chart, your situation should be of similar kind.

I started down the road of creating a service, but then Andries Jansen van 
Rensburg (thanks!) showed me an easier way.

Here's the method which streams the filePath out - you need to supply it a 
valid MimeType - "application/octet-stream" will normally force the browser 
to pop up a Save dialog box.

Cheers,

   /***************************************************************************/
   protected void streamFileContents( IRequestCycle cycle, String filePath,
                                      String fileMimeType )
     throws IOException {

     HttpServletResponse response = cycle.getRequestContext().getResponse();

     byte[] buffer = new byte[BUFFER_SIZE];
     File inFile = new File( filePath );
     FileInputStream in = new FileInputStream( inFile );

     response.setHeader("Content-disposition",
                        "attachment; filename=" +inFile.getName() );
     response.setContentType( fileMimeType );
     response.setContentLength( (int)(inFile.length()) );
     ServletOutputStream out = response.getOutputStream();

     while( in.read(buffer) > -1 ) {
       out.write(buffer);
     }
     in.close();
     response.flushBuffer();
   }
