Application Architecture Trends presentation at Detroit Java User Group meeting

I recently gave a presentation on Application Architecture Trends at Detroit Java User Group meeting on Wednesday evening. The presentation title is "Application Architectures - Where We Have Been, Where We Are Going". The turnout was pretty good (about 20 people) and the presentation went very well. There were lot of great questions and discussion on the items I talked about in the presentation like AOP, Custom Annotations and OSGi. Here is a list of the new technology trends I covered in the presentation:

• Dependency Injection (includes a demo on a Data Access Object using Spring DI to inject the JEE resources like Data Source, Entity Manager, and Transaction Manager)
