Next week (Dec 7 – 10) is the Spring Experience 2005 conference being held in Florida.
The main developers of Spring will be presenting, including Rod Johnson and Juergen Hoeller.
Some of the topics being covered include: Spring Basics, Testing with Spring, Spring ORM, Advanced IoC.
This should be a great conference to get immersed in this framework which is starting to pick up critical mass and a lot of users.
