I have a java desktop application that must unzip a rar file I execute it with command as if it were console by means of the Runtime.getRuntime().exec(l); method in debug mode works perfectly but when I run it does not extract all the file and the same thing happens to me with a class of connection to sql server in debug connects and makes the insert but I run it and it does not even enter the class. This happens on any machine that runs it.
