No support for Nashorn in Java 17
The feature was deprecated in Java 11. It was completely removed in Java 15.
SQLcl ONLY support Oracle Java 11 and 17 today, so you need to run 11 if you want to use the script command to work with js.
What happens if you try with Java 17?
How to fix it
You have two options, Oracle Java 11 or the GraalVM for Java 11.
Faster always sounds good to me, let’s give that a try!
I’m going to get Oracle GraalVM Enterprise Edition 188.8.131.52 Windows x86 for Java 11, Download GraalVM
I simply unzip that.
Then open a cmd prompt.
Then let’s run our script command, again.
Using JAVA_HOME to tell SQLcl where to find Java
That’s brand new in SQLcl 22.1. On Windows, the native EXE was coded to go straight to the Windows Registry to look for Java. It made switching between versions of Java on Windows painful.
Now, if you use a Windows Installer to put down Java 11, it should setup your Windows machine to use it by default, and SQLcl will be impacted by that.
But now in 22.1, you can simply set JAVA_HOME to the Java Home you want the sql.exe to use, and you’re good. Turloch, if you’re reading this, we all say, ‘Thank you!’
