I’ve just posted the first release of the S3Blobs Play Framework Module. This module makes it easy to upload and download files from Amazon S3 from a JPA entity in a Play Framework Java application. This module is based on a POC that I did a few months ago, the JPA stuff from Tim Kral, and the modularization done by Roderik van der Veer. For more details on how to use the module check out the documentation, my tutorial (slightly out of date now), and the source code. This makes it really easy to save file uploads to an external system when running Play! apps on Heroku. Let me know if you have any questions. Thanks!
