The CICS® Transaction Gateway requires a supported version of Java™. A JVM is installed with the CICS Transaction Gateway installation.
The default behaviour of CICS Transaction Gateway is to use the JVM installed with the product or you can configure a supported JVM that has been installed independently of CICS Transaction Gateway. See Specifying the JVM to configure the JVM to use.
The DVD and product download files for CICS Transaction Gateway for Multiplatforms provide JVM installers for use with remote Java applications.
