Looking for AOP framework

["Witt, Mike (OH35)" <mike.witt@xxxxxxxxxxxxx>]

I'm planning to spend some time experimenting with AOP.  I'm wondering if a
de facto AOP framwork is emerging.  Right now, I'm looking at AspectJ and
Spring, there are probably others as well.  So, I'm looking for an opinion
on which framework to use based on:

- What's the standard
- Which one is the most newbie friendly - available documentation and
tutorials
- Eclipse plug-in support
- Hibernate support
- Most active development community

Thanks for the suggestions.
