Deserialization of Soap Fault into custom exception class: possible?

[Nol]

Hi all,

My webservice throws an exception, which is translated into a soap
Fault in the soap message body. See below for the actual message format
as it is send by the server. On the (dotNet) client I get (catch) this
as a SoapException (or SoapHeaderExcep tion). The SoapException contains
various (string type) fields. For example, the Message fields contains
the fully qualified name of the exception on the server side. The
InnerException field however is always null.

What I would like to do is to have the Soap Fault deserialized into a
class wich is similar as found in the the detail field of the Soap
Fault. In other words, I just would like to have the exception in the
same format it is defined on the server. For this I could catch the
SoapException, and parse it's fields, but would rather have the
SoapFault automatically deserialized into the target exception type.

I've been experimenting with the annotations in my client code (proxy),
but I haven't been successful. Actually, I am getting doubtfull if
possible at all.

Here is the message as send by the server:

<env:Envelope xmlns:env='http ://schemas.xmlsoap .org/soap/envelope/'>
<env:Header/>
<env:Body>
<env:Fault>
<faultcode>env: Client</faultcode>

<faultstring>co rp.cpwr.hybrid1 1.application.b usiness.common. MyDomOpSvcExcep tion:
User Defined Exception: MyDomOpSvcExcep tion</faultstring>
<detail>
<ns1:MyDomOpSvc Exception
xmlns:ns1='http ://common.business .application.hy brid11.cpwr.cor p'
xmlns:xsi='http ://www.w3.org/2001/XMLSchema-instance'>
<ns_key:key
xmlns:ns_key='h ttp://application.alt uradev.compuwar e.com'>UDEXC_My DomOpSvcExcepti on</ns_key:key>
</ns1:MyDomOpSvcE xception>
</detail>
</env:Fault>
</env:Body>
</env:Envelope>
In my client code (in the class that extends
WebServicesClie ntProtocol), I defined a class with a signature like
this:

[System.Serializ ableAttribute()]
[System.Xml.Seri alization.XmlTy peAttribute(Nam espace =
"http://common.business .application.hy brid11.cpwr.cor p")]
public abstract partial class MyDomOpSvcExcep tion
{

wich contains a key property. Before the client class definition I
added the following annotation:
[System.Xml.Seri alization.XmlIn cludeAttribute( typeof(MyDomOpS vcException))]
This however doesn't help: I still get SoapExceptions, and the
innerexception is still null.

Anybody any clue?

Thanks in advance,
Nol
