The image O_1035.gif shows the J2EE Connector Architecture. It shows a JVM connected by a network to an Enterprise Information System. The JVM contains an OC4J instance and a Resource Adapter. The OC4J instance contains a J2EE Application Component. An Application Contract (Client API: CCI, specific) exists between the J2EE Application Component and the Resource Adapter. System Contracts (Quality of Service) exist between the OC4J instance and the Resource Adapter. All communication from the J2EE Application Component and the remote Enterprise Information System goes through the Resource Adapter.
