JEE applications

CICS® Transaction Gateway implements the JCA by providing JEE resource adapters.

These resource adapters support the JEE Common Client Interface (CCI) defined by the JCA and are a middle-tier between JCA-compliant applications and CICS Transaction Gateway. The JEE application server can run locally on the same machine as CICS Transaction Gateway, or remotely.

JCA-compliant applications can be developed and deployed in a managed or nonmanaged environment. In a managed environment, JCA applications can exploit the quality of service provided by the JEE application server.
