I'm currently having a problem opening my JAR file. I'm using NetBeans 6.7. It compiles successfully with no errors and I've a JAR file in my DIST folder. What happening is: Whenever i click on the file, command prompt opens up and within a second, it closes. THAT's it. No error code nothing. I've already tried adding new Environment Variable (JAVA_HOME) and pointed it to my JDK folder. Nothing is happening. Please help me out. ALSO: Do i need to download JRE in order to open up JAR file? Somewhere I read, JRE is already included in the JDK?

    Open a command window, navigate to your DIST folder, and run this command: `java -jar yourjarname.jar` and see what the error is. – icza Nov 01 '14 at 13:20

    On python, for example if you open a program from command prompt it executes quickly and then closes the cmd. Is your program with GUI or console based? Not sure about JAR-s tho. – charen Nov 01 '14 at 13:31

For Command Line Applications, the Windows command prompt command java -jar jarfile.jar will compile and execute your jar file. double clicking is when you want to run GUI applications.
