Example:

 
 <hibernate-mapping>
 
   <typedef name="documentTypeEnum" class="com.jalios.jcms.db.GenericEnumUserType">
     <param name="enumClass">com.jalios.jcmsplugin.myplugin.DocumentType</param>
     <!--<param name="identifierMethod">toInt</param>--> <!--default: name-->
     <!--<param name="valueOfMethod">fromInt</param>--> <!--default: valueOf-->
   </typedef>
 
   ...
