OutputStream out = blobDomain.getBinaryOutputStream();
byte[] buffer = new byte[8192];
int bytesRead = 0;
while ((bytesRead = in.read(buffer, 0, 8192)) != -1) {
out.write(buffer, 0, bytesRead);
in.close();
return blobDomain;
public static synchronized void downloadFile( String fileName, BlobDomain blobDomain )
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext extContext = facesContext.getExternalContext();
Long length = blobDomain.getLength();
String fileType = MimeTypes.getMimeType(fileName);
HttpServletResponse response = (HttpServletResponse) extContext.getResponse();
response.setHeader("Content-Disposition", "attachment;filename=\"" + fileName + "\"");
response.setContentLength((int) length.intValue());
System.out.println(fileType);
response.setContentType(fileType);
try {
InputStream in = blobDomain.getBinaryStream();
