org.eclipse.persistence.sessions.DatabaseLogin
Purpose: Hold the configuration information necessary to connect to a JDBC driver.
Description: A DatabaseLogin is used by an EclipseLink database session to connect to a JDBC server.
Responsibilities:
- Hold the driver class name and URL header
- Hold the database URL
- Hold any driver-specific database connection properties (e.g. "user", "database")
- Build the JDBC driver connect string
- Hold the database platform (e.g. Oracle, DB2)
- Hold the message logging stream
- Hold other assorted configuration settings
