Answer 1

Do you have the JPA/JPA2 interfaces included in your project? If you are using maven, you need to include a dependency for the classes. I assume that they are since there are no red lines appearing in the import declarations, but just to be safe, you should validate that they exist.

For a JPA2 dependency, you can use:

    org.hibernate.javax.persistence
    hibernate-jpa-2.0-api
    1.0.0.Final
