Subject [jira] Updated: (AXIS2C-1071) WSDL2C, ADB & xsi:type based deserialization
Date Wed, 05 Aug 2009 17:11:14 GMT


Dimuthu Gamage updated AXIS2C-1071:


Commited the patch provided by Sergio(from revision 801306).

It is a really great patch. I wrote a simple test case (attached) and polymorphic types are
working as expected  :) 

I had to do few changes though like,
1. adding "xsi:type" attribute at the serialization
2. there were variables declared in the middle of the blocks. That is not compiled in Visual
Studio compilers.

> I have the problem of having to work with a wsdl interface the makes use of type extensions
and xsi:type. For example:
>          <complexType name="VirtualHardware">
>             <complexContent>
>                <extension base="vim25:DynamicData">
>                   <sequence>
>                      <element name="numCPU" type="xsd:int" />
>                      <element name="memoryMB" type="xsd:int" />
>                      <element name="device" type="vim25:VirtualDevice" minOccurs="0"
maxOccurs="unbounded" />
>                   </sequence>
>                </extension>
>             </complexContent>
>          </complexType>
> where the VirtualDevice type is extended in various ways to reflect different kind of
device types:
>          <complexType name="VirtualController">
>             <complexContent>
>                <extension base="vim25:VirtualDevice">
>                   <sequence>
>                      <element name="busNumber" type="xsd:int" />
>                      <element name="device" type="xsd:int" minOccurs="0" maxOccurs="unbounded"
>                   </sequence>
>                </extension>
>             </complexContent>
>          </complexType>
> The issue I am running into is that WSDL2C does not seem to support this kind of xsi:type
based type serialization/deserialization (which admittedly fits really poorly with a non-object
oriented language like C). You could probably make it work by storing type information in
the generated structs, combined with a type registry.
> Any suggestions on workarounds other than using the XML model?
