Re-write the MessageBodyWriterJSON with this

import javax.ws.rs.core.MediaType; 
import javax.ws.rs.ext.Provider; 

import org.codehaus.jackson.jaxrs.JacksonJsonProvider; 
import org.codehaus.jackson.map.ObjectMapper; 
import org.codehaus.jackson.map.SerializationConfig; 

@Provider 
public class MessageBodyWriterJSON extends JacksonJsonProvider { 
            public MessageBodyWriterJSON (){ 
            } 

        @Override 
            public ObjectMapper locateMapper(Class type, MediaType mediaType) 
        { 
        ObjectMapper mapper = super.locateMapper(type, mediaType); 
        //DateTime in ISO format "2012-04-07T17:00:00.000+0000" instead of 'long' format 
            mapper.configure(SerializationConfig.Feature.WRITE_DATES_AS_TIMESTAMPS, false); 
            return mapper; 
        } 
}
