I've made a small desktop Java Swing App and decided I want to make it readily available for my non-technical friends (or anyone else I want to show it to) to install on their computer (regardless of OS). I'm using Linux Mint. I have come accross a lot of different approaches (Launch4J, JavaPackager and other similar) but I have not succeded. Installed Launch4J but it simply won't load and failed to setup JavaPackager. This is the app. I'm sorry that I'm not able provide specific information, perhaps some of the answers can direct me towards specifying my issue, as I don't know exactly what I have to do and how. I suppose I have to package the jar artifact my IDE has creates (jar artifact works fine in-IDE but I need to "deploy/distribute" the app).
After some more searching I came across this and I was able to make my jar executable through the help of @samuelowino 's answer. I'm still not sure if this is platform independent (or you need to install some other jdk to run) so I'm leaving the question open until I make sure.
