Hi, By default Servicemix will install CXF feature which have JAX-RS implementation, and resteasy is another JAX-RS implementation. The error you encounter basically means CXF JAX-RS implementation was loaded(you can see it's kind of the JAVA SPI mechanism in OSGi container), but not the resteasy one.
You didn't say what's the exact Servicemix version you're using, if it's 4.5.x, you can uninstall "Apache CXF Runtime JAX-RS Frontend" bundle and install resteasy implementation as bundles so that the OSGi container can use resteasy as JAX-RS implementation. －－－－－－－－－－－－－ Freeman(Yue) Fang Red Hat, Inc.
