Missing Atmosphere and Jersey Dependencies

I'm trying Atmosphere with Jersey to be able to send messages to users. However, when requested by the Jersey endpoint, the following message and result in a ServletException appears in the log.

SEVERE: The following errors and warnings have been detected with resource and/or provider classes:
  SEVERE: Missing dependency for method public void org.apache.cxf.jaxrs.provider.JSONProvider.setMessageContext(org.apache.cxf.jaxrs.ext.MessageContext) at parameter at index 7
  SEVERE: Missing dependency for field: private org.apache.cxf.jaxrs.ext.MessageContext org.apache.cxf.jaxrs.provider.RequestDispatcherProvider.mc
  SEVERE: Missing dependency for method public void org.apache.cxf.jaxrs.provider.JAXBElementProvider.setMessageContext(org.apache.cxf.jaxrs.ext.MessageContext) at parameter at index 1
  SEVERE: Missing dependency for field: private org.apache.cxf.jaxrs.ext.MessageContext org.apache.cxf.jaxrs.provider.MultipartProvider.mc
  SEVERE: Missing dependency for method public void org.apache.cxf.jaxrs.provider.JAXBElementProvider.setMessageContext(org.apache.cxf.jaxrs.ext.MessageContext) at parameter at index 13
  SEVERE: Missing dependency for field: private org.apache.cxf.jaxrs.ext.MessageContext org.apache.cxf.jaxrs.provider.FormEncodingProvider.mc

The stacktrace part:

SEVERE: Allocate exception for servlet AtmosphereServlet
javax.servlet.ServletException
    at org.atmosphere.cpr.AtmosphereServlet.init(AtmosphereServlet.java:540)
    at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1173)
    at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:809)

I use Maven and added the following dependency:

<dependency>
  <groupId>org.atmosphere</groupId>
  <artifactId>atmosphere-jersey</artifactId>
  <version>0.6.3</version>
</dependency>

What am I missing? Thank!

Apparently, the problem was that there were two JAX-RS implementations in the application. This can be resolved if Jersey only scans a package containing Rest classes, and therefore does not know about other JAX-RS implementations.

<servlet>
  <description>AtmosphereServlet</description>
  <servlet-name>AtmosphereServlet</servlet-name>
  <servlet-class>org.atmosphere.cpr.AtmosphereServlet</servlet-class>
   ...
  <init-param>
    <param-name>com.sun.jersey.config.property.packages</ param-name> 
    <param-value>mypackage.with.the.rest.classes</param-value>
  </init-param>
</servlet>

Atmosphere.
