We are using jbossws-cxf-3.1.1.GA. We have tested the Apache CXF JAX-RS samples, but they don't work.

According to the release notes, that version of JBoss Web Services - Stack CXF is based on CXF 2.2. Apache CXF provides a JAX-RS 1.0 implementation since version 2.2.

¿The JAX-RS funcionality implemented by Apache CXF is fully included in JBoss Web Services - Stack CXF?

In case of a negative answer, i would want to know if ¿Its planned to be included in the future?

We get this error:
