hi there!

Im facing download problem from alfresco repository.
my different methods of uploading is successful, but while downloading im stucking up at this code :

downloadAction code:

Content[] readResult =  WebServiceFactory.getContentService().read(new Predicate(new Reference[]{contentReference}, storeRef, null), Constants.PROP_CONTENT);

and the error it throws is:
