Not what could cause that other than there is already a component  
called viewResolver in that Spring context or the Spring context in  
another webapp -- the current code isn't real forgiving about that.

Do you know if that might be the case?

If you don't have any issues sharing your spring.xml file, we're happy  
to take a look.  Your openejb.log should have some good info we can  
use as well.

Feature requests welcome -- all that spring support has been pretty  
much user driven.
