The image shows J2EE connector architecture, which consists of the following components: the J2EE application server, the application component, the resource adapter, and the enterprise information system (EIS). The J2EE application server handles connection pooling, transaction management, and security management. The J2EE application server and the application component manage container-component contracts. The J2EE application server and the resource adapter manage system contracts for connection management, transaction management, and security management. The application component and the resource adapter manage application contracts. The resource adapter and the enterprise information system (EIS) use an EIS-specific interface to communicate.
