Axis problem - null field

[Mat]

Hello,

I try to invoke two methods that access to a field.
The first sets the value of the variable.
Then the second displays the value on the Tomcat console.
But the problem is that the attribute IS null when I invoke the second method.
I obtain the following output:
[one] FOO
[two] null

Where is the mistake?

Cheers,

-Mat
===== Foo.jws =====
public class Foo {

private String foo = null;

public void one() {
foo = "FOO";
System.err.println("[one] "+foo);
}

public void two() {
System.err.println("[two] "+foo);
}
}

==== TestFoo.java ====
import localhost.foo.Foo_jws.*;

public class TestFoo {
public static void main(String [] args) throws Exception {
FooService service = new FooServiceLocator();
Foo foo = service.getFoo();
foo.one();
foo.two();
}
}
