CICS Transaction Gateway Liberty JCA ECI sample code

Pre-reqs

• CICS Transaction Gateway v8.1 or later
• WebSphere Liberty 8.5.5 FP3 or later with the jca-1.6 feature installed or
• CICS TS V5.3 with Liberty and the cicsts:jcaLocalEci-1.0 feature
• Eclipse with WebSphere Development Tools installed

Configuration

The supplied server.xml file shows the required configuration paramters for adding the ECI resource adapter, creating a connection factory and adding the classes supplied with the resource adapter to the classpath of the application. This file can be used as-is or the configuration options can be copied into an existing server configuration.

Compiling the sample

The sample servlet code can be added to a Web Project. To correct any compilation errors either the cicsjee.jar should be added to the build path if using the CICS TG, or the CICS Liberty JVM server libraries added using the Add Library menu if using the CICS Explorer SDK for Servlet and JSP support.
