Re: How do I deserialize the detail field in AxisFault to build MyException?

[Mariano Eloy Fern�ndez]

Hello,
MyException is declared correctly, i think. Here's the WSDL segment.
  <complexType name="MyException">
   <sequence>
    <element name="clave" nillable="true" type="xsd:string"/>
    <element name="localizedMessage" nillable="true" type="xsd:string"/>
   </sequence>
  </complexType>
......
        <wsdl:fault name="MyException">
           <wsdlsoap:fault use="encoded" 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; 
namespace="someUri"/>
        </wsdl:fault>

Yes, I guess I am using Axis the normal way. Interface -->WSDL-->stubs 
and skeletons.
I am using axis both for publishing the service and for calling it from 
the stub client.
However, I am getting rid of the classes generated from the types in WSDL.
Why? Because I already have them. They are the same classes I have on 
the server, including
MyException. Sure, I could use MyException generated by Axis, but, why, 
having the original MyException class?

My goal is to make the stub client throw instances of MyException (my 
implementation of MyException)
transparently, not letting the ones using the stub provided by Axis know 
anything else.

A different thing is Axis not supporting what i need, say, making me 
subclass AxisFault, which I stated I'll try to avoid.
However, if everything else fails, well....

Thanks again Sunil.
Mariano.

Let me elaborate further. I think if your exception structure is 
declared correctly in WSDL then the framework comes into picture only 
when you generate java/.NET server/client code from it. 

When I say subclass AxisFault I assume that you go the normal way of 
generating a java interface ---> WSDL ---> stubs and skeletons.
and you use only Axis all the way. 

I think its your "framework" which has to generate correct code based 
on WSDL. When I say subclass AxisFault I mean if you use Axis then 
that's the way.

If you want to get hold of XML and use a handler then I think that 
should work too.

Hello,
Thanks Sunil, I have already seen people subclassing AxisFault, 
but I 
refuse doing such a thing.
MyException is a "ServiceException", and should know anything 
about 
being published with Axis.
Imagine just tomorrow I decide to move onto some other framework 
to 
publish/call Web Services.
Then what, should I subclass some other different FrameworkFault? 
Of 
course not.

My idea is to get grip of that XML provided in the AxisFault on 
the 
client Stub, unwrap MyException and throw it,
so that the stub throws true MyException instances (or 
RemoteExceptions, 
if some ConnectRefused-like occurs)

In all, I�ll keep on trying, and thanks a lot for your comment.
Mariano.

No, you don't have to do it manually. Just make sure that your 
     

WSDL 
   

correctly reflects the structure of MyException. I found that 
     

java2wsdl 
   

tool somehow misses the structure of application-specific 
     

exceptions. 
   

To get hold of the exception use try-catch mechanism. Note that 
MyException should subclass AxisFault. 

If you still have problems then let me know so that I can send 
     

you a 
   

sample code.
I hope that helps.

Hi,
Some additional notes.
The XML comes in a protected attrbute called faultDetails, 
inaccesible.The public detail field is null.
The question stands, How do I build MyException from this AxisFault?

Thanks,
Mariano.

Hello,
I am working with Axis 1.1
I have a class MyException extends Exception thrown in the Web 
Service. Both De/Serializer are provided for MyException.
An AxisFault is received in the client with MyException as an 
    

         

XML in 
  

       

the detail field of AxisFault.
How do I build MyException from that XML? Do I have to do it 
    

         

manually? 
  

       

Then what's the MyExceptionDe/Serializer for?
Thanks,
Mariano Eloy Fern�ndez.
