Hi team,

My code is working to download a file from portlet but in browser ,while downloading, it do not show file size to be downloaded.
I have also set the content length in resourceresponse but its not working.

Please help.

String mimetype =    doc_file.getMimeType();          
				if (mimetype == null) 
				{           
					mimetype = "application/octet-stream";       
				}
				res.setContentType(mimetype); 
				System.out.println("Size in header >>> "+(int)doc_file.getSize());
			
				
				
				res.addProperty( HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\""+DocumentUtil.docNamingConvention(doc_file.getTitle(), "get") +"."+doc_file.getExtension()+"\"" );
				res.addProperty(HttpHeaders.CONTENT_LENGTH,Long.toString(doc_file.getSize()));
				//res.setContentLength(37402);
				OutputStream out=null;
				
				out = res.getPortletOutputStream();
				FileInputStream input = (FileInputStream) doc_file.getContentStream();
				
				
				
				
				byte[] buf=new byte[4096];
                int bytesread = 0, bytesBuffered = 0;
                while( (bytesread = input.read( buf )) > -1 ) {
                    out.write( buf, 0, bytesread );
                    bytesBuffered += bytesread;
                    if (bytesBuffered > 1024 * 1024) { //flush after 1MB
                        bytesBuffered = 0;
                        out.flush();
                        //System.out.print();
                    }

                }
	
				prefMM.setValue("downloadS", "done"); /// updating prefrence
				prefMM.store();
			
				input.close(); 
				out.close(); 
				

Thanks in advance.
