Since the NamedQuery can be applied only to the Entity class, and, as any annotation, cannot be applied more than once, I have a limitation - 1 NamedQuery per 1 Entity. But, I need often more then 1 NamedQuery. What strategy of using NamedQueried is recommended for the EJB3.0 environments?

Hi sw79,

i think you are missing the @NameQueries annotation:

Code:

@NamedQueries ( {
      @NamedQuery (name = "syscounter.findAll", query = "select sc from SystemCounter sc"),
      @NamedQuery (name = "syscounter.findByName", query = "select sc from SystemCounter sc where sc.name = :name")
}) 

Hope this helps!
