Hi! I cleared EJB6Developer this saturday with 90%
In preparation i read ejb3.1 spec (exclusive chapters about compatibility with 2.1) and tried some SCBCD5 mocks. Also, i had experience with EJB3.0.
In exam most of questions were about common features of 3.0 and 3.1 and also i didn't seen any questions about embeddable usage and EJBLite requirements.
This exam doesn't harder, than SCJP.
