you can also set up injections via web.xml.  Even without this how is  
this dangerous?  The injection map isn't supplied by user code but by  
server code.

I'm not sure if the standalone tomcat annotation support actually does  
anything.  I wrote it to mimic the functionality of the original  
standalone support (which again IIRC didn't appear to connect to  
anything useful) when getting annotation/injection support to work in  
a way useful to geronimo.  Geronimo uses xbean-reflect to handle  
object creation and configuration which is a very elegant solution IMO.

I'll try to find some time to remind myself of how this works and  
comment on it.... but it may be a while.
