Axis Web Service return NULL array to .NET Client

After reading this thread, my problem doesn't solve.

http://www.codecomments.com/XML_SOAP/message700023.html

The cause, in my code, was xml namespace specified in WSDD. Look your WSDL and set right namespace in wsdd.

Axis Version: 1.3
.NET Framework: 1.1
WSE: 2.0 SP3

Java Web Services and class of returning object:

public UtenteSemplice[] Search(String semericerca) throws Exception {
       UtenteSemplice[] b = new UtenteSemplice[2];
       b[0] = new UtenteSemplice();
       b[1] = new UtenteSemplice();
       b[0].setNomeutente("aa");
       b[0].setPassword("aapsw");
       b[1].setNomeutente("bb");
       b[1].setPassword("bbpsw");

       return b;
}

public class UtenteSemplice {
   
    /** Creates a new instance of UtenteSemplice */
    public UtenteSemplice() {
    }
   
    private String m_nomeutente;
    private String m_password;

    public String getNomeutente() {
        return m_nomeutente;
    }

    public void setNomeutente(String nomeutente) {
        this.m_nomeutente = nomeutente;
    }

    public String getPassword() {
        return m_password;
    }

    public void setPassword(String password) {
        this.m_password = password;
    } 
}

Axis WSDD:

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
    xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

  <service name="ContattiService" provider="java:RPC" style="wrapped" use="literal"> 
    <parameter name="className" value="it.atreeblu.atreeflow.services.ContattiService"/>
    <parameter name="allowedMethods" value="*"/>

  <beanMapping qname="ns:UtenteSemplice" xmlns:ns="http://services.atreeflow.atreeblu.it"
    languageSpecificType="java:it.atreeblu.atreeflow.services.UtenteSemplice"/>
 
  </service>
</deployment>

Piece of WSDL where I found correct namespace (autogenerated from axis):

<wsdl:types>
    <schema elementFormDefault="qualified" targetNamespace="http://services.atreeflow.atreeblu.it">
