Here is a short video on the JD Edwards Trial Edition that is found in the Oracle Cloud Marketplace. If you want to experiment with a pretty current version of JDE (9.2.3) with relatively little effort, this is the way to go.
I was able to set it up in about an hour. However, in full disclosure, I had been working in Oracle cloud provisioning a full JDE implementation and so I was able to move through some of the steps fairly quickly because I was already very familiar with them.
