org.eclipse.persistence.sessions.Login

Purpose: Define the information required to connect to an EclipseLink session.
Description: This interface represents a generic concept of a login to be used when connecting to a data-store. It is independent of JDBC so that the EclipseLink session interface can be used for JCA, XML, non-relational or three-tiered frameworks.
