Hello Pentaho community,

There are a couple of posts on the forum regarding te execution of Jar (Java) files.
However, there are none that provide a minimalistic, complete, and reproducible .zip example which simply:

-Passes a String to the Jar from Kettle.
-Receives a String back to Kettle from the Jar.
-Provides the source code that compiles into the Jar, so a decompiler is not needed.

If anyone can provide a .zip that suffices, I think it would be helpful for the entire Java-Pentaho community to get started.
