Presentations
Java/J2EE Architecture @ Work: EJB 3 vs Spring and Hibernate
You've used EJB in the past and been disappointed - it was too heavy and difficult to use. Like Bruce Tate, maybe you've gone from “Bitter” to “Better, Faster, Lighter”. With EJB 3 shipping in early 2006, maybe it's time to take another look. We'll compare EJB 3 with alternative
frameworks - Spring and Hibernate - to see if EJB 3 has closed the gap.
J2EE Security @ Work: J2EE Meets JAAS
Have you wasted time writing lots of security-based code and ever wondered if there's a
better way to add security to your application? Are you confused by declarative security?
Have you read about JAAS (Java Authentication and Authorization Service) but wondered where
it fits? Have you ever said, “Can I just see a working example”? If so, then this talk is for you.
Java/EE Web Services and SOA @ Work: Architecture & Development
Have you tried to deploy J2EE Web Services and thrown up your hands in frustration at the lack of tool support? Do you want to know how to develop and deploy Java EE-compliant Web Services so that they work every time? Would you like to see how to develop/deploy Web Services in Spring with XFire? Are you wondering if SOA is just hype and fluff? Do you think SOA is just marketing's re-packaging of Web Services? Would you like to know how Web Services and SOA (Service-Oriented Architecture) fit together? If so, then this talk is for you.
