Why we cant execute the built JAR?

If we built it manually by IDE

What happens?

How are you running it?

[marble breach]

I mean when you build the project it gives you a jar file right?

Manual build

And why we cant open it

[upper tusk]

Well how are you opening the JAR?

[marble breach]

Double click

[upper tusk]

Can you try running it from the command line with java -jar?

btw that's the wrong user

What happens when u click the built file?

Is it executing main method

[upper tusk]

that as well

But I'm mainly interested in what happens when running it with java -jar

[marble breach]

You mean from CMD?

[upper tusk]

yes

I'll try when i get home. Yesterday i tried it wih another program but it didnt work when i type java or javac to console. It says there is no such thing. Is it because i dont have JDK installed?

[upper tusk]

I'd need to see the output to see what the issue is

Try running it with java -jar yourjar.jar where yourjar.jar is your JAR file
