Simmilar to the original Lotus Notes Java-API, domingo has a factory class that must be used to instantiate a concrete implementation of the domingo interface classes.
DNotesFactory factory = DNotesFactory.getInstance();
The factory instance can now be used to establish a session and to interact
with the Lotus Notes Client or a Lotus Domino server. The following code
creates a session to a Lotus Domino server and opens the database
names.nsf on that server.
DSession session = factory.getSession("plato.acme", "username", "password");
DDatabase = database = session.getDatabase("", "names.nsf");
The following class diagram shows the main interfaces of the domingo API:
