How to solve NoClassDefFoundException while junit test?

I want to use JUnit tester to my Java program, but I got java.lang.NoClassDefFoundException. As I read this may got if I don't have .class file. But, since first I use it with javac, as I think it must be there.
Here is my command line:
myComputer\java\bead2>javac -cp .;junit-4.12.jar;hamcrest-core-1.3.jar
snake\tests\ToApplesTest.java
myComputer\java\bead2>java -cp .;junit-4.12.jar;hamcrest-core-1.3.jar
org.junit.runner.JUnitCore snake\tests\ToApplesTest
JUnit version 4.12

Why this crashing for me?

Try snake.tests.ToApplesTest. You must provide a package name, not a path to the containing folder.

I'm trying to create .jar artifact, that I could just double click start.
I think that the problem means that this class cannot find some resources. The JOGL/JogAmp official sites gives explanation on deployment of .jars with JOGL, but I think that I missed something.
The Test1.jar has following structure:
Test1.jar/
--com/
----company/
------Main.class
--jar/
----gluegen-rt.jar
----gluegen-rt-natives-windows-amd64.jar
----gluegen-rt-natives-windows-i586.jar
----jogl-all.jar
----jogl-all-natives-windows-amd64.jar
----jogl-all-natives-windows-i586.jar
--lib/
----windows-amd64/
-------gluegen-rt.dll
-------joal.dll
-------jocl.dll
-------jogl_cg.dll
-------jogl_deskop.dll
-------jogl_mobile.dll
-------nativewindow_awt.dll
-------nativewindow_win32.dll
-------newt.dll
-------soft_oal.dll
--META-INF/
----MANIFEST.MF
--com
--jar
--lib
--META-INF
manifest.mf contains -
Manifest-Version: 1.0
Main-Class: com.company.Main

By the stack trace it seems that the JVM cannot find the class com.jogamp.opengl.GLEventListener that means it can't resolve the path to the included jar files. The path of the jar files is not correct. Follow the link to see how to package jars correctly.

Java exception error after exporting javafx jar

Exception in thread "main"
I've even created a MainTerminal class that doesn't use javaFX, instead just interacts within the terminal and after I exported the jar using MainTerminal as the main class and it worked fine. It seems I'm not being able to export some dependency or something but I checked the buildpath and it seemed alright to me.

I feel quite dumb about this but I just found out what my problem was. I was exporting my project as a Jar instead of a runnable Jar, that's why it was throwing an exception when I tried executing it.

Java webstart stopped working after Java 7 update 45 for jcl-over-slfj4.jar

My application is using Java web start with JNLP. After installing all Java 7 related updates my application was running fine but when I added jcl-over-slf4j-1.1.1.jar file in the lib folder then my application stopped working. When I remove it the application worked fine again.
NOTE: This application is also using Log4j jar file.
Not sure if the issue is with this jar file or with my application.
Here is the corresponding stack trace for this issue:
