Introduction to Java EE Connector Architecture
Java EE Connector Architecture (JCA) is a standard architecture for connecting enterprise information systems (EIS) such as CICS, IMS, Sap, Siebel, Peoplesoft, JD Edwards, and Oracle. JCA standardizes the way that Java EE application components, Java EE compliant application servers, and EIS resources interact with each other. Resource adapters and application servers implement the contract defined in the JCA specification. Resource adapters run in the context of the application server and enable J2EE application components to interact with the EIS using a common client interface. JCA compliant application servers can support any JCA compliant resource.

JCA was developed under the Java Community Process as JSR 16 (JCA 1.0) and JSR 112 (JCA 1.5), which is the current version.
