non-bean class

[mkprim]

Hi I have a class that implements a web service, and has this method
public void placeChatEvent(ChatEvent evt)

But this ChatEvent is a complex type, so whenever I try to deploy the wsr, axis tries to
find out the complex type and generate a descriptor.
However I get this error:

[Types] The class com.primary.common.events.ChatEvent extends non-bean class com.primary.common.events.GenericRequest. An xml schema anyType will be used to define com.primary.common.events.ChatEvent in the wsdl file.

However, my GenericRequest adjusts to the JavaBean Specification.
Here is the GenericRequest Code:

public abstract class GenericRequest extends GenericEvent {

 private SessionID sessionId;
 private User user; // Para ser llenado en el server
 private String requestId;

 /**
 * Default constructor
 */
 public GenericRequest() {
 super();
 }

 /**
 * Se recomienda usar este constructor
 * @param type
 */
 public GenericRequest(int type){
 super(type);
 }


 /**
 */
 public abstract void doAction(MarketsApi mApi) throws ServerException;

 /**
 * @return el Id de Session
 */
 public SessionID getSessionId() {
 return sessionId;
 }

 /**
 * @param sessionID el Id de Session
 */
 public void setSessionId(SessionID sessionID) {
 sessionId = sessionID;
 }

 /**
 * Devuelve el identificador del pedido unico para este cliente
 * Es el mismo que tiene el request
 * @return int el identificador del pedido unico para este cliente
 */
 public String getRequestId() {
 return requestId;
 }

 /**
 * Setea el identificador del pedido unico para este cliente
 * Es el mismo que tiene el request
 * @param int el identificador del pedido unico para este cliente
 **/
 public void setRequestId(String requestId) {
 this.requestId = requestId;
 }


 /**
 * @return Returns the userId. Para ser usado en el servidor
 */
 public String getUserName() {
 return user.getName();
 }

 /**
 * @return the user (filled in the server)
 */
 public User getUser() {
 return user;
 }

 /**
 * @param userId The userId to set. Para ser llenado en el server
 */
 public void setUser(User user) {
 this.user = user;
 }

}

Can anybody please help me? I think this might have a simple solution that I just cannot see because i'm a newbie in webservices and axis.
Thanks a lot,
Marcelo
