Java Web Start ClassNotFoundException - java

I'm trying to launch a runnable JAR file via web start, but am encountering an error with java not being able to find an external JAR (I think). When running the JNLP file, JWS starts, but then states that the application cannot be opened due to this error:

The external JAR file mentioned, apache commons, is embedded in the runnable JAR and the JAR runs fine on it's own, just not in JWS. Suggestions?

Deploying JavaFX Application with Intellij

I created quite complex project with JavaFX and now I'm having some trouble deploying it, as I never deployed any app in Java before.
I tried using Intellij "Build artificial" but I always get "Error: corrupted jarfile" when I try to open the the Jar it builds.
Any suggestions? I'm using external libraries from Maven and some local ones too if it helps...
Edit:
Ok I changed some of the settings in the Make Artificial, now I don't get that error.
I get this Exception, seems it can't file the fxml file...

NoClassDefFoundError When Running Jar?

I've got a project that runs fine in IntelliJ IDEA 2017 (a simple board game), which is a JavaFX Project. I've set this up to export as a jar using File > Project Structure > Artifacts > + > JAR > From Module With Dependencies which generated a jar file.
However when I run this jar using java -jar program.jar, I get the following exception:

Exception running application main.Main
The important part of that is the NoClassDefFoundError from main.GameManager, line 23. This line is creating a new instance of an object, the class for which is in a separate package.
Any ideas on how to fix this issue?
Thanks!

Exported Javafx application does not run as Jar file (Eclipse)

I have a javafx application which is not properly exporting to a runnable jar file from eclipse. When exported the .jar file does not properly run and the GUI does not appear. Below is the Manifest File.
Manifest-Version: 1.0
Class-Path: .
Main-Class: gameaspects.SourceCodeVersion9
Here is the export interface:
Exporting the file produces no errors or warnings from eclipse.
Running the application from cmd I get the following error:

Exception running application gameaspects.SourceCodeVersion9
The code that I believe that this is referring to is this:
List<String> result = Files.find(Paths.get(".\\music"), 100,
(p, a) -> p.toString().toLowerCase().endsWith(".mp3"))
.map(path -> path.toString())
.collect(Collectors.toList());
The .\music refers to the source folder music that is present in my application.
If any other information is needed to diagnose this issue please comment below and I will add it.
Ok using java -jar FileName.jar in command prompt and then using the stack trace to debug my code I was able to find the error with my application.

It looks like you are missing:
qpid-common-0.10.jar
Available from http://qpid.apache.org/download.html
or
<dependency>
<groupId>org.apache.qpid</groupId>
<artifactId>qpid-common</artifactId>
<version>0.10</version>
</dependency>
if you are using maven.
