Strange behaviour on WebService annotated class

[andrea81it]

Hello,
i'm developing en EJB3 module on JBoss 5.1.10. It contains several beans with relative webservice class using @WebService() annotation.
My dev environment is NetBeans 6.8 on Winxp; i also have a test environment on a linux server.
It works all fine except for an operation: on my Winxp server instance, there's a missing complex type in the wsdl exposed, but the same EAR deployed on the test linux server works fine.

Let me explain with a scrap of source:

EJB source:

public MessageListResponse getSentMessages(Integer limit, Integer offset) {
...

DTO sources:

public class MessageListResponse extends Response implements Serializable, Cloneable {

    private static final long serialVersionUID = -8044091577142524000L;
   
    private List<Message> messages = null;

    public MessageListResponse() {
    }

    public MessageListResponse(List<Message> messages) {
        this.messages = messages;
    }

    ...getters+setters...
   
----------------

public class Response implements Serializable, Cloneable {

    private static final long serialVersionUID = -5113231551096825487L;

    private Boolean error = false;
    private Boolean warning = false;
    private Boolean info = false;
    private String errorMsg = null;
    private String warningMsg = null;
    private String infoMsg = null;
   
    ...getters+setters...

WS class source:

@WebMethod(operationName = "getSentMessages")
public MessageListResponse getSentMessages(@WebParam(name = "limit")
Integer limit, @WebParam(name = "offset")
Integer offset) {
    return ejbRef.getSentMessages(limit, offset);
}

Ok. Take a look at the generated wsdl:

WSDL generated on localhost (winxp):

<xs:complexType name='getSentMessagesResponse'>
    <xs:sequence>
        <xs:element minOccurs='0' name='return' type='tns:response'/>
    </xs:sequence>
</xs:complexType>

WSDL generated on test env (linux):

<xs:complexType name='getSentMessagesResponse'>
    <xs:sequence>
        <xs:element minOccurs='0' name='return' type='tns:messageListResponse'/>
    </xs:sequence>
</xs:complexType>

Any ideas?

Need more infos about platform/dev environment?
Thankyou very much.
