Class as WS return parameter

Hi all, 
 I am having a problem with my web service. I've created a web service that
it has a signature as below:

public ReturnFlight findFlight(String fromCity, String toCity, String
dtDeparture, String dtArrival){

Where ReturnFlight is a class that I defined earlier with two attibutes. 

I am using AXIS 1.2 and I put this class (ReturnedFlight) into
WEB-INF/classes. My web service is published on
http://localhost:8080/Flight.jws. And the problem is that when I run my
simple Axis example to execute my web service, at first time it gave me a
message that I did not have serialized my class bean(ReturnedFlight). 

 I've tried to solve this problem putting the server-config.wsdd in my
WEB-INF directory, but when I do that I receive an error execution on my
http://localhost:8080/Flight.jws. The problem is actually occuring when I
try this code in AXIS:

 call.setReturnType( XMLType.XSD_ANYTYPE );
 ReturnFlight ret = new ReturnFlight();
       ret = (ReturnFlight) call.invoke( new Object [] { fromCity,
toCity,dtDeparture,dtArrival });

I did not get any answer because I think it did not know how to work with my
ReturnFlight class. 

One more thing, if I am monitoring on the server side(Tomcat), I can saw
that my service has got actually the result that I want, but it did not
arrive to the client side. 

What do I must do to manage a class on returning parameters? 

Here below, I put my server-config.wsdd, I do not know if it is correctly or
not...

Help me, please!!!
