java -jar (runnable) vs java -cp (no runnable)

Question

I created a web client that invokes a service in OSB exposed through CXF (wsdl2java). I created a maven project and have imported sources. In addition, I added CXF libraries to the project. I use IDE is Eclipse, and running the class containing the main method invokes the service perfectly and it responds.

Then I exported the project as runnable jar and when I run the command: java -jar myJar.jar the following exception occurs:

I have reviewed the MANIFEST, and I see that the variable 'Class-Path:' contains all necessary libraries and other variable 'Main-Class:' indicates the main class containing the main method.

However, if I run the command (on the root of the project) mvn clean install (which creates a jar) and run the following command: java -cp myJar.jar myPackage.MainClass, the execution is successful.

I know there's some question about 'java -jar java -cp myJar.jar VS myJar.jar myPackage.MainClass' but honestly do not understand why the first option causes the exception I mentioned, can anyone tell me what is?

Thank you very much.
