After having released and obtained the .jar file if I go to start it with a batch file of the type java
-jar c: \ prog1 \ Objects \ prog1.jar c: \ prog1 \ Object \
starts correctly
But if I go to d use Launch4J.exe to have an exe containing both the jar file and the Java runtime, the program does not start
How to monitor the point where the program start stops?
