All,
I have a web service implemented in Java using Axis. In this service, I have
a method that takes some simple params and returns a single attachment.
Following the Axis examples, I have defined the signature of this method as:
public DataHandler fileReadAttach(AvakiPrincipal principal, String path,
long offset, int count)
throws RemoteException;
Then, I use java2wsdl wrapped/literal to generate a WSDL for this. The
relevant parts of the WSDL are as below:
<element name="fileReadAttachResponse">
<complexType>
<sequence>
<element name="fileReadAttachReturn"
type="apachesoap:DataHandler"/>
</sequence>
</complexType>
</element>
...
<wsdl:operation name="fileReadAttach">
<wsdlsoap:operation soapAction=""/>
<wsdl:input name="fileReadAttachRequest">
<wsdlsoap:body use="literal"/>
</wsdl:input>
<wsdl:output name="fileReadAttachResponse">
<wsdlsoap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
Notice how the attachment refers to an apache:DataHandler element. This
works without a problem when I write Java/Axis clients that target this
service. However, .NET won't even swallow the WSDL because it does not
recognise the apachesoap namespace.
My question is: why isn't the generated WSDL something like:
<wsdl:operation name="fileReadAttach">
<wsdlsoap:operation soapAction=""/>
<wsdl:input name="fileReadAttachRequest">
<wsdlsoap:body use="literal"/>
</wsdl:input>
<wsdl:output name="fileReadAttachResponse">
<mime:multipartRelated>
<mime:part>
<wsdlsoap:body parts="body" use="literal"/>
</mime:part>
<mime:part>
<mime:content part="docs" type="text/plain"/>
</mime:part>
</mime:multipartRelated>
</wsdl:output>
</wsdl:operation>
Seems to me that's how it should come out. How do I make it so?
For giggles, I changed the WSDL by hand and tried to generate stubs for it.
wsdl2java failed to do so, with a NullPointerException:

Any idea why Axis is failing on what looks like a legitimate WSDL? Should I
open a bug? Thanks!
