java.lang.ClassCastException: class org.apache.cxf.bus.CXFBusFactory

bhoflack May 11, 2011 9:48 AM

Hi,

when i try to deploy my cxf-jaxrs app i get a class cast exception when it's starting the service. I verified with the examples-cxf-rs project provided with servicemix and i get the same exception.

How can i solve this? I'm using Apache ServiceMix (4.3.1-fuse-00-00)

Hi,

Do you mean you saw class cast exception when you run examples-cxf-jaxrs shipped with kit? I just tried it and it's working ok from my side.

Could you elaborate what's your cxf-jaxrs app looks like and what's the class cast exception you get? The full stacktrace is more helpful here.

Hi,

Sorry, I can't reproduce this problem.

Did you just try the cxf-jaxrs example shipped with kit or did you ever revise cxf-jaxrs example?

Hi,
Did you install other version of CXF bundle?
