Logging In to a Session

Before you can use a session, you must first log in to the session using Session method login.

By default, when you load a session using the session manager, TopLink automatically logs in to the session using the zero-argument login method. For information on loading a session without automatically logging into the session, see "Loading a Session Without Logging In".

If you load a session without logging in, you can choose from the following signatures of the login method:

• login(): Use the Login, user name, and password defined in the corresponding sessions.xml file.

• login(Login login): Override the Login defined in the corresponding sessions.xml file with the specified Login.

• login(String username, String password): Override the user name and password defined in the corresponding sessions.xml file with the specified user name and password.

When you log in to a session broker, the session broker logs in all contained sessions and initializes the descriptors in the sessions. After login, the session broker appears and functions as a regular session. TopLink handles the multiple database access transparently.
