Multiple annotations found at this line:
- cvc-complex-type.2.4.a: Invalid content was found starting with element 'mapping-file'. One of '{"http://xmlns.jcp.org/xml/ns/persistence":shared-
cache-mode, "http://xmlns.jcp.org/xml/ns/persistence":validation-mode, "http://xmlns.jcp.org/xml/ns/persistence":properties}' is expected.
- Mapping file "orm-namedquery-config.xml" cannot be resolved.
