Currently ODE JBI requires wsdl & xsds to be unpacked in Service Unit. This is not required restriction.
I've committed a solution for it for ODE 1.X.
For example of how it works, please check out distro/src/examples-jbi/maven2/ping-pong example.
Integrated in ODE-1.x #23 (See http://hudson.zones.apache.org/hudson/job/ODE-1.x/23/)
: Implement classpath resolved xsd & wsdl imports
Integrated in ODE-1.x #25 (See http://hudson.zones.apache.org/hudson/job/ODE-1.x/25/)
