Trying to Make the Jar File Run on Arch Linux

[psygo]

I'm trying to run the `jar` file through the following command (I've also tried within the same directory):

Code: Select all

java -jar gowrite2_3_2_3/GOWrite.jar

However, what I get back is this:

Code: Select all

Here is my Java version (`java --version`):

Code: Select all

openjdk 21 2023-09-19
OpenJDK Runtime Environment (build 21+35)
OpenJDK 64-Bit Server VM (build 21+35, mixed mode, sharing)

Does anyone know what's going on? Any ideas of a possible solution?

In the error log:

Caused by: java.awt.HeadlessException:
No X11 DISPLAY variable was set,
or no headful library support was found,
but this program performed an operation which requires it,

This indicates that you might have only the -headless java package installed (such as openjdk-21-jre-headless). This is good for many server use-cases, but GOWrite needs "full" jre (for swing support).

You were 100% correct! Thanks, Lauri!

Doing a:

Code: Select all

pacman -Syu jdk-openjdk

And replacing the headless version with the full one did the trick.
