How to program using the ECI resource adapter provided by
the CICS® Transaction Gateway.
Overview of the JCA programming interface
JCA connects enterprise information systems such as CICS, to the JEE platform. JCA
supports the qualities of service provided by a JEE application server
(security credential management, connection pooling and transaction
management).
The Common Client Interface
The Common Client Interface (CCI) of the JEE Connector
Architecture provides a standard interface that allows developers
to communicate with any number of Enterprise Information Systems (EISs)
through their specific resource adapters, using a generic programming
style.
Using the ECI resource adapter
A JEE developer can use the ECI resource adapter to access CICS programs,
using COMMAREAs and channels, to
pass information to and from the server.
Compiling applications
To enable Java™ applications
to be compiled in a managed or nonmanaged environment, the relevant
.jar details must be added to the class path.
Integration testing JEE components using an intercept plug-in
You can use integration test tools to intercept ECI calls from Java Enterprise Edition components. This feature
allows such components to be tested without requiring a running CICS Transaction Gateway or CICS server.
JEE tracing
In a nonmanaged environment where the default connection
manager is used, the application can set the LogWriter property
on the class to define where trace messages are sent.
Resource adapter samples
The resource adapter samples consist of ECI COMMAREA and channels and containers samples.
Assistance in coding CCI applications
When coding CCI applications, refer to the Javadoc and
the specification for the JEE Connector Architecture (JCA).
