Add new fields to "user" table in hibernate DB

I added new fields to "user" table in "hibernate" DB.
And I would like to use these fields via "PentahoUser" object.

Although I modified "IPentahoUser.java" and "PentahoUser.java", they cannot be recognized.
How can CRUD processes for these fields be done via "PentahoUser" object?

Any help is appreciated and thanks in advance.
