Hi Lorenzo,
Let me give the configuration of what I am using.
Axis 1.1 running under Tomcat 5.0.27
I think you have to subclass your Exception from AxisFault and then try to
catch exception on the client side.
Here's how my exception hierarchy looks
java.lang.Object
|
+--java.lang.Throwable
|
+--java.lang.Exception
|
+--java.io.IOException
|
+--java.rmi.RemoteException
|
+--org.apache.axis.AxisFault
|
+--MyException
Here's how my WSDD looks:
service name="Bank" provider="java:RPC" style="wrapped" use="literal">
<operation name="withdraw" qname="ns4:withdraw" returnQName="ns4:accepted"
returnType="xsd:boolean" xmlns:ns4="http://example";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<parameter qname="ns4:account" type="xsd:string"/>
<parameter qname="ns4:amount" type="xsd:int"/>
<fault class="example.MyExceptionType" qname="ns4:MyException"
type="ns4:InsufficientFundFaultType"/>
</operation>
<requestFlow>
<handler type="soapmonitor"/>
</requestFlow>
<responseFlow>
<handler type="soapmonitor"/>
</responseFlow>
<parameter name="sendMultiRefs" value="false"/>
<parameter name="wsdlServicePort" value="Bank"/>
<parameter name="className" value="example.BankSoapBindingImpl"/>
<parameter name="allowedMethods" value="withdraw"/>
<parameter name="wsdlServiceElement" value="BankService"/>
<parameter name="wsdlTargetNamespace" value="http://example"/>
<parameter name="wsdlPortType" value="Bank"/>
<parameter name="sendXsiTypes" value="false"/>
<parameter name="scope" value="Session"/>
<typeMapping
deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
encodingStyle="" qname="ns3:MyException"
serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
type="java:example.MyException" xmlns:ns3="http://example"/>
</service>
Note that the exception class fields come under details element. And here's
how its sent to the client:
?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server.generalException</faultcode>
<faultstring></faultstring>
<detail>
<ns1:fault href="#id0" xmlns:ns1="urn:banktest"/>
<ns2:exceptionName
xmlns:ns2="http://xml.apache.org/axis/";>example.MyException</ns2:exceptionNa
me>
</detail>
</soapenv:Fault>
<multiRef id="id0" soapenc:root="0"
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
xsi:type="ns3:MyException"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:ns3="urn:banktest">
<errorDesc xsi:type="xsd:string">Invalid date format</errorDesc>
<errorCode xsi:type="xsd:int">1220</errorCode>
</multiRef>
</soapenv:Body>
</soapenv:Envelope>
A very good reference on exception handling is here:

I hope that helps.
