Just in case you weren't aware there is just one more week for you to submit a session abstract to Oracle OpenWorld which will get you a free pass to the conference.
From the JDeveloper/ADF perspective we are always looking for customers to share their experience. So even if you never presented before, this can be your big break.
You can submit to the general Middleware track or to the more technical Oracle Develop track, based on the content you have.
Some suggestions for sessions:
Deep dive on a capability you implemented in your project.
Tips sessions - the best advices you can give based on your experience.
Hope to see you at Oracle Open World.
