Really great summary for EJB's and their basic functionality. Arun gives the information in a clear & concise way which is really useful for getting through the subject matter quickly. I used this as a refresher course as I've been put on an EJB project and haven't worked with JEE in a long time. My only reason for 4 stars, and not 5, is I would like to have seen a bit more detail on EJB transactions. These have been tripping me up a bit, especially when they rollback and updates to the DB are then not committed. Thank-you for a great course!
