J2EE defines the J2EE Connector Architecture (JCA) as a standard architecture for connecting the J2EE platform to heterogeneous Enterprise Information Services (EISs). By defining a set of scalable, secure, and transactional mechanisms, the JCA enables the integration of EISs with application servers and enterprise applications. This enables multi-channel clients including Web clients, application clients, Web Service clients, and wireless clients to seamlessly access a Dynasty server.
