The EPI resource adapter provides a high level CCI interface to the EPI which can be used to install terminals and run 3270-based transactions on a CICS® server.
The EPI resource adapter can be deployed into a JEE application server to allow JEE enterprise applications to access CICS. When the JCA is used, connection pooling, security, and transaction context are managed by the JEE application server not the application. Automatic Transaction Initiation (ATI) is not supported.
CICS Transaction Gateway Desktop Edition: Support is not provided for the JCA resource adapter.
