Hello Rafal, first of all, finders allow you to fetch only local interface[s], not entity's fields. ejbSelect methods allow you to fetch one field per ejbSelect. So, you should declare ejbSelect method like: /** * @ejb.select query="SELECT DISTINCT mp.mediaId FROM Media2Project WHERE mp.projectId = ?1" */ public abstract Collection ejbSelectDistinctMediaId(int projectId);
