Hi, The warning message implies that the canonical metamodel classes [1] corresponding to the persistent domain classes had not been generated and/or available. Since JPA 2.0, type-safe queries [2] are made possible with the introduction of instantiated meta- classes and these classes could be generated from annotated Java source during normal compilation process by invoking an annotation processor [3]. If the application is not using type-safe queries -- one can safely ignore these warnings -- but I agree they do appear to be annoying.
