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

The CTGTesterCCI application
The CTGTesterCCI enterprise application contains a Java servlet and a session
bean that we used during this project in our various test scenarios. It is intended
to provide a simple enterprise application that can be used “out of the box” to test
ECI connectivity from any CICS Transaction Gateway to any configured CICS
region using the CICS ECI resource adapter. It is written for simplicity and thus is
not intended as a real-life customer application. All input parameters can be
specified as HTTP query strings or HTML form parameters, and all output is
through text-based HTML.
It has the following features:
► Setting of the COMMAREA input, encoding, and length
► Setting of CICS TG Java client and CCI trace
► Executing a program a number of times
► For an unmanaged connection, setting of the CICS application server, CICS
mirror transaction, CICS user ID, and password
► For an unmanaged connection, setting of the Gateway daemon URL and port
The application consists of a number of JSPs, a servlet, and an enterprise bean.
Figure B-1 on page 338 illustrates the complete architecture of the enterprise
application.
