.jar file cant find main class

ok, i made a game which consisted of two java files:
- BettingGame.java
- BettingGame_MainClass.java.

I compiled them and got:
- BettingGame.class
- BettingGame$Listener.class
- BettingGame_MainClass.class

I threw in a manifest file stating the following

Code:

---

Main-Class: BettingGame_MainClass\n
\n

---

and created the .jar file in terminal with the following command:

Code:

---

jar cfm BettingGame.jar manifest.txt BettingGame_MainClass.class BettingGame.class BettingGame$Listener.class

---

and i succesfully got a .jar file.

When I tried to run the .jar file using:

Code:

---

[java -jar BettingGame.jar

---

I get the following errors


Exception in thread "main" java.lang.NoClassDefFoundError: BettingGame$Listener

Where did i go wrong?
I followed the steps from this video: YouTube - How to create Java executables/jar file

P.S. The java program itself works fine. it compiles and runs with no errors.

You can inspect the .jar file with e.g. winzip; check if that nested class made it in your .jar file. According to the exception stack trace, it didn't.

kind regards,

yeah that worked! Thanks again, Jos!
