How to resolve a Camel-CXF Web Service client ClassNotFoundException - web-services

Question

I'm having a painful time resolving a Camel-CXF ClassNotFoundException. I've included a sample program exhibiting the problem
You can find the source code at:
git#bitbucket.org:levonk/camel-cxf-example.git
To run the program after checking out the project run:
mvn test exec:java
Here is the exception stack trace:

This is an issue with the maven Exec Maven plugin not picking up the classes generated from your WSDL at runtime.
The correct way to do structure this sort of thing in Maven is to separate your WSDL -> Java generation out into a seperate project, and add a dependency on that project in your cxf-client. This way, the generated code is just a dependency like any other. See https://github.com/FuseByExample/smx-ws-examples for an example of how to do this.
