I am using Excelsior JET to convert my JAR into an EXE.
I want my application to be Standalone. Literally one single file without needing installation. JET creates an EXE and also a runtime folder.
The solution, according to them, is to use 7z to create a self-extracting file (into a temporary) that will run the application.
The problem is that the self-extraction takes a long time, so program startup is ridiculous.
So my question is: is there another alternative to pack my EXE and runtime into a single standalone file?
