In case you haven't heard we are holding a free online virtual developer day next week - July 10th that you should attend - even if you think you already know ADF.
While one of the tracks is aimed at developer who are relatively new to ADF - and cover ADF Faces, ADF Controller and a comparison of productivity with Forms and other tools - the two other tracks have great content on some topics that you might not be familiar with even if you already work with ADF.
This include sessions about the upcoming ADF Mobile, The new ADF support in Eclipse and information about Application Life Cycle Management with ADF and JDeveloper. As well as sessions that will open your mind to the areas where ADF integrates with other Fusion Middleware Solutions such as ADF integration with BI, WebCenter and SOA.
Most of the sessions are quite heavy on demos and you'll get a chance to interact with the presenters and ask questions during the live event.
You should register even if you can't attend the live event - this way you'll get an email pointing you to the recorded sessions for on demand viewing.
