Trying to inject an EntityManager into the Authenticator.java results in the following error noted below:

All I add in this class src/action/org/domain/Blogging/session/Authenticator.java
is the line
@In EntityManager em;
and the import statement.

It should be noted that this then breaks the login screen from coming up.
