We have a ZIIP (small shop, only 2 subcapacity general purpose engines on the
machine besides the ZIIP. I don't know offhand if I have the JDK or just the
JRE. Is there an easy way to find out? Is the JDK an additional cost?
If I run java17 I get this.

The first question to ask is do you have any zIIP processors ? This makes a big
difference if you are planning to run java of any flavor. It will depend on
whether you have the JDK or JRE versions of java on how easy it is to do
development natively on the mainframe

Subject: EXTERNAL Email: converting Cobol to java - remaining on the mainframe
Hi list,
We have a Cobol/VSAM/CICS+batch application that the developers want to convert
the Cobol/VSAM part to Java/Db2, still residing on the mainframe. I have java
8 (both 31 bit and 64 bit) as well as java 11 and 17 on the mainframe - the
parts that are "no additional cost" with z/OS 3.1. Is this all I need to
develop java applications on the MF or are there additional java compilers or
other pieces that I would need to purchase to make this a viable option? At
this point the only java we use is what IBM ships ( like SCRT).
TIA
Rex
