IBM Redbooks are the most useful source of information for such queries

a staring point would be a google search with
ibm redbooks java


also googling with something like
zos executing a jar container from jcl

will return quite a bit of informations

When I tell somebody to RTFM or STFW I usually have the page open in another tab/window of my browser,
so that I am sure that the information requested can be reached with a very small effort

what happened when you googled with
"zos icl example to run java jar"


I got many links that answered your question

for example https://www.ibm.com/developerworks/syst ... atchz.html

up to you to investigate further
