data. In Spring you must as well supply wiring information about how the component is connected to other components thru setters. You need to describe the life cycle, if there are any initialization and destruction methods of the component and the names of them. You need to describe the life style, if it is e.g. a thread safe or poolable component.
I don't want to go into a debate on Dependency Injection versus Locator (there's an article by Martin Fowler out there that talks about the pros and cons of each approach). I just want to point out that using DI does not rule out the possibility of doing lookups. In Spring, for instance, you can implement the ApplicationContextAware interface and get handed an ApplicationContext that you can use to look up other components a-la Avalon.
