Summary

 


Coping with the number of components involved with writing a GUI front-end to a CICS application may at first seem a daunting task.   Since most of most of the components also run on multiple platforms, the task may seem insurmountable.   My recommendation is to put the environment together in steps:

  • Install a CICS server on the platform of your choice.
  • Install the CICS Client on a platform that can support the CICS Gateway for Java.   Configure the CICS Client for communications to your CICS server.  Verify that your CICS Client is installed and communicating properly to your CICS Server..
  • Get the CA03 SupportPac and prepare the CICS based, ECI callable backend CICS programs.   Test the programs using the transactions supplied in CA03.
  • Install the CICS Gateway for Java on the machine containing the CICS Client you just installed..
  • Install JDK 1.1 (the current level) and compile the Java program supplied with this SupportPac.
  • Use the 'appletviewer' program supplied with JDK 1.1 to test the Java applet and communications to the CICS Gateway for Java and on to the CICS Server.  When starting the appletviewer from a command prompt, the command prompt window becomes your 'Java console'.  I left in tons of debugging messages to you should see lots of messages in the Java console.
  • Install your web server on the same machine containing your CICS Client and CICS Gateway for Java.  Configure the web server to point to your Java Applet.
  • Use you web browser (at the appropriate level) to test the entire environment.

There are many steps to complete the entire environment, but most of the software involved has quite good documentation.  If you do have problems, go back to the basics and think of testing scenarios that can rule out specific software components as being the problem (e.g. can my web browser run any Java Applets, can my web server serve any html pages, etc).

 

Good Luck, have fun!
