Hi, The Java Persistence Criteria API is no so complicated, and I can do it. I believe that you know that if you want to use JPA, you will need to have a Database Bean for the "categories" table and a JPA Controller where this Criteria Query will be placed into. This query is used for displaying all categories and sub-categories, usually used for a site map. Am I right? Kind regards, Tudor
