There are some dependencies to declare in order to implement the codecs. Open the hm-
rs/pom.xml file and add the XML extract from the JSON Module Dependencies listing to the
<dependencies> node; after updating the POM file update the Eclipse project dependencies (see
Updating Project Dependencies on page 146).
