File uploads have long been possible in JSF, usually using third party plugins like PrimeFaces or RichFaces. JSF 2.2 finally adds support for file uploads out of the box. The practical reason for this lag is that the JSF specification has always chosen to support a Servlet version one behind the latest. This is what often makes it possible to use newer versions of JSF on older runtimes, particularly on Servlet containers like Tomcat. Consequently JSF 2.2 can depend on Servlet 3.0 which adds support for multi-part file handling - making the new file upload feature possible. In a pretty well written code driven post, Hantsy Bai explains the file upload support in JSF 2.2/Java EE 7. You can also check out Rama Krishnnan's YouTube video below on the file upload feature:

Interestingly Rama uses Tomcat and an older version of NetBeans but is still able to demo the feature well (he also chooses to do manual header parsing himself). Things are obviously a lot easier with a Java EE 7 server like GlassFish, which is what Hantsy Bai uses instead.
