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!

Product version: IRIS 2019.1

$ZV: IRIS for Windows (x86-64) 2019.1 (Build 510_4_20145U) Tue Aug 25 2020 23:42:27 EDT

Hi Adeel,

IRIS 2019 does not support java 11. I suppose this is the cause of error. The maximum supported version of java is 8. See documentation:

Supported Technologies | InterSystems Supported Platforms | InterSystems IRIS Data Platform 2019.1

It really seems that there is no java executable in the (supposed?) java home directory you specified.

Can you check if the following file exists:

C:\Program Filey\Java\jdk-11\bin\java.exe

Then there may be issues with the java version, maybe not.
