Difficulty getting MEGAN working on unix server

I’ve generally been using the windows version of MEGAN but have been trying to also get it working on a unix server. I installed JDK8 and edited my .bashrc with

export PATH=/home/tyler/software/jdk1.8.0_261/bin:$PATH

I’ve also tried doing the same with javafx-sdk-14.0.2.1. But, I can’t get the software to start. An earlier version installed by someone else on the machine (6.7.7) works just fine, but when I try to run the current version, I get the following in my error.log. I know there are a few posts on this forum with similar errors, but I haven’t been able to get those solutions working.

Any idea why it isn’t liking my currently installed version of java?

Recent releases of MEGAN come with their own bundled JRE. To override the bundled JRE, there is an environment variable INSTALL4J_JAVA_HOME_OVERRIDE that you can set, by typing something like this:

export INSTALL4J_JAVA_HOME_OVERRIDE=/home/parallels/software/jdk

The installed Java must be at least version 13.

However, the error that you reported looks like there is a problem with running Java FX on your system. Please try installing this JDK, which contains OpenJDK:

I will be away for the next ten days, so won’t be able to help until then

Thanks Daniel, I installed Liberica JDK. Still no luck, but I have a new error message now when trying to run the program:

Error occurred during initialization of boot layer
java.lang.module.FindException: Module javafx.swing not found, required by megan

I’ve been looking up how to add --module-paths in java, but I’m not sure how to do that and launch MEGAN. I have this in my .bashrc to identify both my local java and local javaFX to try and fix the module problem (didn’t work).

export PATH=/home/tyler/software/jdk-14.0.2/bin/:$PATH
export PATH=/home/tyler/software/javafx-sdk-14.0.2.1/lib/:$PATH

And then in my .bash_profile I have:

export INSTALL4J_JAVA_HOME_OVERRIDE=/home/tyler/software/jdk-14.0.2/
export PATH_TO_FX=/home/tyler/software/javafx-sdk-14.0.2.1/

Anything that I’m missing?

Update:

I realized I had installed the ‘standard’ as opposed to ‘full’ JDK you recommended. I installed the ‘full’ version, which has the javaJX mods, and updated my .bashrc and .bash_profile with the new directory. But now when I try to run MEGAN, I get this in my error log again:
