Project Structure

HibernateUtil.java:
Sets up connection with Mysql database and connects Hibernate

HelloServlet.java:
Just a servlet to ping that return "Hi!" message

UserDao.java:
The Hibernate ORM class used to map to MySql table that contains User Entity.

UserRegistration.java:
Returns page for user registration under /user_registration servlet

UserRetrieval.java:
Returns page for user retrieval under /user_retrieval servlet

UserService.java:
A service to save and retrieve UserDAO objects into MySql database. It is best to not write such logic in servlet classes and to abstract them out into service class. Hence, this was done for best practices.

Note: Html filles are in /WEB-INF as .jsp files to be used by servlet classes.
