Step by Step Directions:
I’ve been asked many times to show how to make a java program executable. It is actually very easy to make Java executable on any computer.
The main tool you’ll use on a PC is the Command Line or DOS Prompt. To find it click Start and in the box at the bottom type cmd.exe. If you’re on a MAC, just search for terminal in the search box.

You do not know how much you seriously helped me. I have looked all over the internet to kind out how to run a file by just double clicking but all they ever showed was just using Command Prompt/Terminal and that was the end of all their videos. This video explained so well, regardless of even using Terminal, because you also showed the equivalent for Command Prompt in Windows. Again, thank you so much and I will continue to see if there are any other further videos that you have to help me π
awesome man, many thanks
Okay, guys don't forget the
<return> or <enter>
after "Main-Class: Filename" in the text file, or you will get some strange error.
THANK YOU!!
It's sometimes just the simple things that make all the difference.
These guys always leave out the most important things. This does not work most of the time unless certain run time libraries are present..
hello derek , i exported the runnable jar file of your paint app but the resources are not included there . i mean the images for icons doesn't work. what should i do?
Thank you β₯
I do this on my gui programs. I follow all the steps and I created a jar file. But if I open it, nothing happens.
great demonstration!
It gives me an error at the very start. It says as following:
'javac' is not recognized as an internal or external command,
operable programm or batch file.
What am I supposed to do?
What is the difference between this and "Clean and Build Project" on Netbeans ?
this does not help me at all
How long did it take you to become such an excellent and versed programmer?
hey Derek my runs and everything but my photo assets don't show when i run it
When i try to open the .jar file my MacBook says "The Java JAR file could not be launched. Check the console for possible error messages.
Where can I find information on getting rid of the ".jar" in the application name? I have a small app that I made, and I created the .jar, but any java apps I see don't have the .jar extension in the name. It's just an executable with the app name. ???
Good One.
But how can we make an executable jar which has dependency to some other jar?
How can we reference from the command line to that dependency jar so as our App to run successfully?
ur sound is so irritating
Hey @Derek Beans! I have done everything exactly like you but it doesen't work.

Can you please help me
Hi derek, it seems that i cannot run my simple application. It says thatcould not find or load main class, i have changed my directory even to the folder containing the class file . I am using windows. pls help thanks
Hi Derek, having a bit of trouble with this.
I have a main class and another class that is related to this class (extends it).
I made the manifest file and the cmd prompt line, but when I run the jar file I get an error: "a java exception has occurred".
Can you please help? Thanks
its not working in pc
Hi Derek! I am having a problem. I made a simple program called Test to use for this video, which has 2 classes in it, the main one being Test. However, every time I try and run my program, it says "Error: Could not find or load main class Test". This is after following everything you did in the video. Any help fixing this problem would be appreciated! π
I can't even find the files on my mac
If you have .txt files going with your class, where would you save them?
im getting this as an error: Invalid or corrupt jarfile manifest.txt
what does this mean and how can i fix it?
Hey Derek
how do you enhance the "javac -d ../classes *.java" command so that it walks the tree of packages and avoid jamming them into a single location.
Many thanks!
