Object Gateway Server - Java Executable Not Found

Not sure where to ask for some helpful hints about IRIS 2019.1 in 2025, but here goes.

I'm trying to create a new Java gateway to run some Java code through ObjectScript, but I keep getting an error saying "Java executable not found in the given directory":

 This is my Object Gateway Server definition:

 I am not sure what is wrong, whether I am defining this gateway wrong, because I can verify that the executable exists in the provided directory.

Any help or hint is greatly appreciated!
