Overview
Introduction This SupportPac provides a working sample application which uses a graphical user interface (GUI) front end, written using Java(tm), to access the sample CICS application provided in SupportPac CA03. This includes a working program written in Java, additional hints and tips, and instructions for installing and using the samples. The samples are intended to be used by customers needing an initial sample to get them started with their own Java front-end development. The simplest form of Java applet to CICS communications was used for this sample program. The applet uses synchronous ECI calls to CICS programs. This Support Pac was written using the products listed below in Software Environment and Prerequisites, but should run in any environment that support the Java 1.1 specification and connects to CICS using the CICS Gateway for Java V1.1.3 or higher: The programs in this SupportPac are written as a complete sample application, to illustrate various techniques involved in accessing a CICS application from a GUI application written in Java. When used in conjunction with SupportPac CA03, a complete sample solution is provided. The Java Applet (IVPApplet.java) can be retreived by clicking here. The HTML to execute the applet (IVPApp.html) can be retreived by clicking here. Objective The objective of this SupportPac is to provide a working sample application, most of which can be reused with a GUI front-end to a customer application. By having a working sample, weeks or months can be cut from the normal development cycle. Since the objective of this program is to show the interaction between a Java Applet and a CICS program, a very simple GUI interaction was selected. It is up to the user of this SupportPac to develop/modify the user interface in accordance with their company's policies and procedures for developing web interfaces. This document provides additional hints and tips, as well as instructions for installing and using the sample application. Software Environment and Prerequisites This Support Pac was written and tested using the following products, but should run in any environment that supports the Java 1.1 specification and connects to CICS using the CICS Gateway for Java V1.1.3 or higher:
