RESTEasy is a JBoss / Red Hat project that provides various frameworks to help you build RESTful Web Services and RESTful Java applications. It does not have bindings to convert java classes from JSON and vice-versa.

Here comes libraries like JSON-B and Jackson, which helps to convert between java classes and JSON.

From Json-B documentation :

JSON-B is a standard binding layer for converting Java objects to/from JSON messages. It defines a default mapping algorithm for converting existing Java classes to JSON, while enabling developers to customize the mapping process through the use of Java annotations.
