This section of the chapter will explain the concepts of JCA (J2EE Connector Architecture) before we dive deep into Oracle adapters.
JCA was developed as part of the J2EE standards to promote open standards across the Enterprise Application Integration domain. JCA promotes development of adapters for various Enterprise Information Systems.
JCA specification, developed as part of JSR 322, abstracts the system level implementation for integrating J2EE applications with Enterprise Information System.
JCA helps to achieve abstraction in the following:
Connection management with EIS
Transaction management with EIS
Establish the security for EIS connectivity
Life cycle management of resource adapters
Work management for resource adapters with the application server
Transaction in-flow management into the application server
Message inflow management within the application server
