Getting classes in package

Question

Hello,
I have a problem with getting some external classes into my package.
To get a better view over the situation I'll show it as an example:
the class "Zoo" is in the directory: town/district1/
with the follwing content:
package town.district1;
public class Zoo{
Elephant elephant1 = new Elephant();
Ok, my Elephant-class is in directory "pets", pets and town are in the same directorylevel.
Elephant has the following content:
public class Elephant{
//some elephant stuff here
so, from the root-directory of my package structure it looks like:
town/distric1/Zoo.java
pets/Elephant.java
Compiling Elephant is no problem, but if I try to compile Zoo, I keep getting the error:
"cannot resolve symbol", means the compiler doesn't find the Elephant-class. I tried to set several combinations of the -classpath switch to javac, but it still doesn't work. Please note that it is not possible to add package information to the Elephant-class, they have to be kept as they are, modifying the Zoo-class is no problem, as long the package-information is kept.
I would be very happy if there was someone to help me there. Thanks in advance..

Going back to your first post, Elephant is in the pets directory so the path to that directory needs to be in the Classpath. Since Zoo's fully qualified name is town.district1.zoo, the directory that contains the town directory must ALSO be in the classpath.
Lets say you have c:\animals\town\district directory and you have c:\animals\pets\Elephant.class file.
To compile Zoo: javac -classpath c:\animals\pets Zoo.java
Also, Zoo must contain the line "import Elephant:"
I tried this on my system - it works.
public class Elephant {
   public static void main(String[] args) {
      System.out.println(args.length);
package town.district1;
import Elephant;
public class Zoo {
   public static void main(String[] args) {
      Elephant e=new Elephant();
