This is good point, and in fact we did evaluate this route. A benefit  
of our own container that outweighed everything else was that it is  
the most unassuming option. There will never be a conflict with the  
user application using a different version of Spring, etc. The fewer  
dependencies we have, the more self-containing cayenne-server.jar is,  
the easier it is for the end users to include Cayenne in their various  
environments (J2SE, JEE, OSGi, etc.) and various application stacks.

Even Cayenne 3.0 has too many dependencies to my liking. E.g. we are  
on Velocity 1.3, and the Velocity project is at 1.6.2 now. Apache  
Click uses Velocity for template rendering. So Click/Cayenne users  
will need to choose a single version of Velocity and pray that it  
works for both Cayenne and Click. So I sorta wanted to avoid this  
situation with DI.
