I opened the launch script in a text editor and all it says is
cd /home/jjj/Software/TreeForm103/TreeForm/
java -Xmx256m -Xms64m -jar TreeForm.jar
With the command line in ~/Software/TreeForm103/TreeForm I just copied
the above line and ran it, and I got the same error message. Then I
deleted the -Xm... options and ran it bare, and again I got the same
error message. It might be useful to know what those options do. Window
size, maybe? In any event, they don't seem related to the error message.
Checking in Synaptic I have had OpenJDK installed the whole time. Is
there a way to tell the java -jar command which java to use? As for
paths, do you mean the path to the java? I know where the Oracle Java 8
is located, because there were 'install' instructions telling me to put
it in /usr/java/jre1.8.0_381, so that's where I put it. It must be
correct because LibreOffice found it and listed it as available. I don't
know where the others are.
There is a Help file with TreeForm, which says at the top:
To install this software in your computer, unzip the folder in
any folder of your choosing.
This software requires Java 1.4.2 or higher to run. The Java
runtime can be downloaded from the <link>Java Website.</link>
