Dependency question

[Dain Sundstrom]

I've been working on trimming the OpenEJB dependencies and found  
these deps from cxf:

cxf-rt-frontend-jaxws-2.0.2-incubator.jar
 cxf-rt-bindings-soap-2.0.2-incubator.jar
  cxf-tools-common-2.0.2-incubator.jar
   jaxb-xjc-2.0.5.jar
   velocity-1.4.jar
    velocity-dep-1.4.jar
So what are xjc and velocity used for?  More importantly, do I need  
these at runtime?
