How to java on FreeBSD?

[graudeejs]

Test.java

import java.lang.reflect.Array;
class Test
{
        public static void main( String argv[] )
        {
                System.out.println( "Arguments:" );
                int i = 0;
                while( i < Array.getLength(argv) )
                {
                        System.out.println( argv[i] );
                        i++;
                }
        }
}

so how to compile ?

# java Test argument1 argument2 argument3
Exception in thread "main" java.lang.NoClassDefFoundError: Test

Why?
