Servlet cannot find helper class

Question

Hello
Under WEB-INF/classes I put ServletExample and SingletonExample. Compiling ServletExample, that makes use of SingletonExample, works.
In the directory WEB-INF/classes I also have another direcotry, test. And in WEB-INF/classes/test I put again ServletExample and SingletonExample.
Here I have tried in several ways to compile the servlet, but I always get an:
Cannot find symbol class SingletonExample.
I tried writing package test at the top of both files, and even at the top of only one of these two.
I even tried to make WEB-INF/classes/test/ServletExample make use of SingletonExample residing in WEB-INF/classes, but I didnt succeded.
What happens when you have subdirectory in WEB-INF/classes/? I think this is a MUST, to have subdirectory in large webapplication, so I really dont want to put everything in the classes directory.
Do you how to resolve this prolem? And: if Im in WEB-INF/classes/test and want to referr from a servlet residing in this direcory to a Singleton/helper class residing in WEB-INF/classes/, which approach do I have to use?
Thanks
Paolo

Jeez, you aren't gonna get very far in Java like this.
CLASSPATH is wrong - again. You're supposed to give JARs and paths where the class loader is supposed to look, not the actual .class file.
Also, you're not telling the compiler to put the .class file in the package directory structure.
Your example is pretty awful. Try this:
Put this code into c:\common
package common;
import common.test.TestDown;  // What the hell is this?  There is no package test, but there is a package named common.test
public class TestUp
   public void sayHello()
      System.out.println("Hello.....");
}Put this code into c:\common\test
package common.test;
import common.TestUp;
public class  TestDown
   public TestDown()
        TestUp testUp = new TestUp();
        testUp.sayHello();
   public static void main(String[] args)
        new TestDown();
}Open a command shell and navigate to c:\, then do the following:
Directory of c:
07/01/2005  03:43 PM    <DIR>          .
07/01/2005  03:43 PM    <DIR>          ..
07/01/2005  03:45 PM    <DIR>          common
               0 File(s)              0 bytes
               3 Dir(s)  74,909,675,520 bytes free
C:\>javac -d . common\*.java
C:\>javac -d . common\test\*.java
C:\>java -classpath . common.test.TestDown
Hello.....Once you've got your head around this, go learn Ant and have it compile your projects properly.
