Package woes

[Cathy Song]

I have 2 classes(A, B) in a package. -->lev1.lev2.lev3;

So, I created 3 directories lev1, lev2 and lev3 and placed my classes
in lev3.

package lev1.lev2.lev3;
class A {
public static void main(String[] args) {}
}

package lev1.lev2.lev3;
class B {
}

Now when I run A.class, I get the followign error:
java.lang.NoClassDefFoundError: lev1/lev2/lev3/A

Please help!!

To run a class defined in a package, the root directory must be included in your classpath. For example, if you have the following structure:

projects
  \- lev1
      \- lev2
          \- lev3
              |- A.class
              \- B.class

Then the root directory "projects" must be in your classpath and you need to execute the program using the fully-qualified name:
e.g. "java lev1.lev2.lev3.A"
