attempting to use incompatible return type - method getCause()

           Summary: attempting to use incompatible return type - method
                    getCause()
           Product: Axis
           Version: 1.1
          Platform: All
        OS/Version: Other
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: WSDL processing
        AssignedTo: axis-dev@ws.apache.org
        ReportedBy: cwl@free.fr


environment -------------------------
Axis 1.1
java full version "1.4.1_01-b01"
-------------------------------------

I have the following error when I want to compile the code generated by 
WSDL2Java :

D:\WLC\projet\DGI\Service_alertes\_build\client\src\alerte\portailfiscal\impot
s\gouv\fr\AlerteFault.java:33: getCause() in 
alerte.portailfiscal.impots.gouv.fr.AlerteFault cannot override getCause() in 
java.rmi.RemoteException; attempting to use incompatible return type
found : java.lang.Object
required: java.lang.Throwable
public java.lang.Object getCause() {
^
1 error
-------------------------------------------------

This code deployed to Axis server ( I used just the Axis sample 
NoSuchEmployeeFault.java and change the class name ) :

public class AlerteFault extends RemoteException implements Serializable {
private String _info;
public AlerteFault() {
}
public AlerteFault(String info) {
_info = info;
}
public String getInfo() {
return _info;
}
public void setInfo(String info) {
_info =info;
}
}
---------------------------------------------------------

generates from axis server the following wsdl :

<complexType name="AlerteFault">
<sequence>
<element name="cause" nillable=3D"true" type="xsd:anyType"/>
<element name="info" nillable=3D"true" type="xsd:string"/>
<element name="message" nillable=3D"true" type="xsd:string"/>
</sequence>
</complexType>

So it adds the element name "cause" with anyType, since JDK 1.4 there is a new 
method "throwable getCause()" into 
java.rmi.RemoteException which is extend by org.apache.axis.AxisFault.

How can I resolve this bug ?

thanx
