I use an javaws app that comes with a jnlp file. I want to launch it locally and be able to modify the source code on my computer to fit my exact needs. I use Eclipse as IDE.
I've opened the jnlp file and downloaded all the jar files, then I have used JD-GUI and CFR to decompile the app. In Eclipse, I've imported all the different ressources jar and put the app decompiled source code within the src folder. I've tried to correct every mistake done by both softwares but the app still crashes due to their mistakes.
Note, if i just import the app as a jar file, it works as expected but i can't edit the files, indeed it's a class file.
