Compilation Error

I am using jdk 1.5.0_07

When i compile any program (for e.g. the simple one below), the bytecode is generated without error, but when i try to run the program, i get the error:-

Exception in thread "main" java.lang.NoClassDefFoundError: first/java

Please help.

class sample

{

public static void main(String args[ ])

{

System.out.println("Java is better than C++.");

}

}
