jboss fuse 6.2 rest cxf org.apache.cxf.service.factory.ServiceConstructionException: “No resource classes found”

Question

Just started using Fuse 6.2 from 6.1. This deployed on 6.1 and I can't seem to get it to deploy in the new Fuse 6.2. This simple Rest service keeps getting the following error when I deploy to the Fuse environment.

Any ideas would be greatly appreciated.

THis issue suggests removing the javax.ws.rs/javax.ws.rs-api/2.0.1 bundle file from Fuse. The bundle start cleanly without error however the REST service is not accessible for some reason.

I need to investigate the feature Swagger as it starts automatically.

I got the same error. It was caused by a dependency on an old version of javax.ws.rs:

javax.ws.rs;version="[1.1,2)",
javax.ws.rs.core;version="[1.1,2)",

https://issues.apache.org/jira/browse/CXF-5654 states CXF 3.x needs java rs api 2.0. So I added that explicitly:

javax.ws.rs;version="[2.0,3)",
javax.ws.rs.core;version="[2.0,3)",

In the Maven pom.xml:
