Gosh, that README is old. JDK 1.1.7 is from 1997!
What I would like to do is have a 3rd party jar on my system in the classpath for ImageJ or FIJI. I understand that I can set the environmental variable as that README suggests and invoke the java interpreter directly.
What I am trying to figure out is how to load a 3rd party jar file using the ImageJ Launcher.
It seems like some combination of one of these options should do it:
--jar-path, --jarpath, -jarpath <path>
append .jar files in <path> to the class path
pass -classpath <classpath> to the main() method
call the main class with the full ImageJ class path
It seems that whatever I pass to those options the classpath does not change.
