Exception in thread "main" java.lang.NoClassDefFoundError

Hi,

I have 2 classes: Fibonnaci.java and TestFibonacci.java
In the same dirctory, there is also junit.java

Using Console, i've first typed:
javac -cp ./junit.jar Fibonacci.java TestFibonacci.java

Everthing went fine, until I've typed:
java -cp ./junit.jar Fibonacci

The following error appeared:
Exception in thread "main" java.lang.NoClassDefFoundError: Fibonacci

What am I doing wrong? I can't figure out the mistake.

Here is my code:

TestFibonacci.java

import junit.framework.*;

public class TestFibonacci extends TestCase {
    Fibonacci f;

    public TestFibonacci(String name) {
       super(name);
    }

    public void setUp(){
      f=new Fibonacci();
    }

    public static Test suite() {
      return new TestSuite(TestFibonacci.class);
    }

    public void test1() {
        assert(f.compute(1)==1);
    }

    public static void main(String args[]) {
       junit.textui.TestRunner.run(suite());
    }

}

and Fibonnace.java

class Fibonacci
{
     public int compute (int n)
     {
         if (n<2)
    return n; //bug; should be "1"
         else return compute(n-1)+compute(n-2);
      }
}
