CICS Transaction Gateway V5 The WebSphere ... - IBM Redbooks

► The Common Connector Framework (CCF) classes.
These classes implement the CCF interfaces and programming model. The
CCF is comprised of three core components: the CCF classes, the Enterprise
Access Builder, and the Java Record Framework.
► The Common Client Interface (CCI) provided by the J2EE Connector
Architecture.
These classes define a standard architecture for connecting the Java 2
Platform Enterprise Edition (J2EE) platform to a heterogeneous EIS such as
CICS. Java applications interact with resource adapters using the Common
Client Interface (CCI), which is largely based on the CCF, but it is a standard
that is open to the entire Java community.
1.2.3 External Security Interface
The ESI is used for verifying and changing the user ID and password information
held in the CICS external security manager (ESM), such as RACF. It is based on
the CICS Password Expiration Management (PEM) function. For further details
on programming with the ESI, refer to Chapter 4 “ECI and ESI applications”, in
the redbook Java Connectors for CICS, SG24-6401.

ESI calls to CICS can only be made using the ESIRequest class provided by the
CICS TG base classes. This class provides a Java interface to the ESI, and
provides two simple PEM requester functions:
Verify Password Allows a client application to verify that a password
matches the password for a given user ID stored by the
CICS ESM.
