Java client application compatibility

Compatibility of Java client applications with different versions of the CICS® Transaction Gateway API.

You do not have to recompile Java client applications if you migrate them to a new environment, for example if you:

  • Upgrade the JVM on the client system
  • Use a different operating system
  • Update a remote CICS Transaction Gateway to a later version
  • Change the topology from local mode to remote mode

You must use a JRE version that is supported by the version of the ctgclient.jar that you have deployed with your Java client application.
