How do you run Java Puzzle Ball ?

9a14f127-8560-49af-a391-1434f9fe7f39 Apr 27, 2017 9:43 PM

I've downloaded the JavaPuzzleBall jar file and now I'm trying to run it.

I've tried

java -jar JavaPuzzleBall.jar

java -cp JavaPuzzleBall.jar javafxapplication01.JavaPuzzleBall

I've tried extracting the contents of the jar file into a directory and then, from this directory, running

java -cp . javafxapplication01.JavaPuzzleBall

I've tried all the above using -classpath instead of -cp

In all cases the response I get is

Error: Could not find or load main class javafxapplication01.JavaPuzzleBall

I can see the JavaPuzzleBall.class file in the jar file in the correct location and when I extracted the contents it was there in the javafxapplication01 directory.

I've downloaded the jar file three times in case it had been corrupted, but still the same result.

Any ideas what the problem may be ?

Hi Stuart,

I remember encountering a bug like this before. I think my problem was that I hadn't set an environment variable properly on the machine I was using. One indication that this might be the problem is if the error occurs with other .jars. Are you able to run other jars on your machine?

Yes. Created a jar with a simple Hello World program and ran it from the same directory as the PuzzleBall jar

java -jar Test.jar
Hello World!

java -jar JavaPuzzleBall.jar
Error: Could not find or load main class javafxapplication01.JavaPuzzleBall

I have two Java Virtual Machines 8 and 9, the game works for me only with java 8, Whats your JVM? you can know that with the command java -version.

I did this

$ java -version
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

$ java -jar JavaPuzzleBall.jar

openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-8u121-b13-0ubuntu1.16.04.2-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)

Could it be because I'm using openJDK instead of Oracle JVM ?

Strange... I'll see if I can get some advice on this.

I had same problem on Ubuntu with openJDK. Installed Oracle JDK and it works fine now.

If you are using gentoo javafx useflag should be enabled.

I have the following java JDK's implemented:

To execute I simply double click on the JavaPuzzleBall jar file.

No problem.

No environment variable mods to run the puzzleball game. Only needed mods which Nick and mNem helped me with to perform command line compiling using Java 8 and 9.

Here is my solution solution,

I am using Windows 10 OS.

Make sure you are using JDK 1.8 and download the game from the following link:
https://apexapps.oracle.com/pls/apex/f?p=44785:112:118335702021467::::P112_CONTENT_ID:19394

After downloading just double click on the JavaPuzzleBall.jar file or you can run through the cmd command, type java -jar JavaPuzzleBall.jar, (C:\Users\computername\Downloads>java -jar JavaPuzzleBall.jar)

I hope this helps.
