The jaxrs-2.1 and earlier features provide the com.ibm.websphere.jaxrs.providers.json4j.JSON4JObjectProvider
class as a built-in
MessageBodyWriter and
MessageBodyReader to serialize and deserialize JSON payloads using JSON4J.
The restfulWS-3.0 feature does not provide a default MessageBodyWriter or MessageBodyReader class for serializing and
deserializing JSON using JSON4J. Remove the JSON4J code from your application and instead use the JSON-B feature and the JSON Packages it provides for
serializing and deserializing. See JSON4J to JSON-P switch demo,
for a demonstration on how this can be done. Alternatively you can package your own MessageBodyReader and MessageBodyWriter with your own JSON4J implementation in your
application.
This rule is flagged once per Eclipse project or Java archive.
