In example below see how to use Jackson JSON provider instead of embedded in eXo RESTful framework.

Create subclass of javax.ws.rs.core.Application with code as bellow and add it to the eXo Container configuration.

package org.exoplatform.test.jackson;


import org.codehaus.jackson.jaxrs.JacksonJaxbJsonProvider;


import java.util.HashSet;

import java.util.Set;


import javax.ws.rs.core.Application;


public class Application1 extends Application

{

   @Override

   public Set<Class<?>> getClasses()

   {

      Set<Class<?>> cls = new HashSet<Class<?>>(1);

      cls.add(Resource1.class);

      return cls;

   }


   @Override

   public Set<Object> getSingletons()

   {

      Set<Object> objs = new HashSet<Object>(1);

      objs.add(new JacksonJaxbJsonProvider());

      return objs;

   }

}

In this example we assumes Resource1 is Java class which carries JAX-RS annotations and it uses JSON. In this case RESTful framework will use JacksonJaxbJsonProvider for serializing/deserializing of all messages to/from Resource1. But it will not impact to other services in any kind.
