[Axis2] SoapFault in Axis2

[David]

hi,

I was using Axis 1 to make my webservices but now I'm trying Axis 2, and I
don't know how to manage my errors, for sample I was using AxisFault
exception in Axis 1 to answer that I couldn't execute normally the service,
and instead of sending a normal xml response I was answering :

Code:
<soapenv:Fault>
    <faultcode>01</faultcode>
    <faultstring>Not working</faultstring>
    <detail>
        <PARAM1>3</PARAM1>
        <PARAM2>hello</PARAM2>
    </detail>
</soapenv:Fault>

How can I do it in Axis2 architecture ?

thx
