Good question. In a DIME version of my service, I continued with the same
signature as in my original mail:
public DataHandler fileReadAttach(AvakiPrincipal principal, String path,
long offset, int count)
throws RemoteException;
However, in the implementation, I made sure to set the attachment type to
DIME. As a result, when I write Axis clients, I can see that the attachment
format on the wire is _not_ MIME, but I can't tell whether or not it's
really valid DIME.
Why? you may ask. Well, I can't really write .NET clients that target this
WSDL because of the _same_ problem I had earlier in this thread. Axis sets a
type of apachesoap:DataHandler on these attachments and .NET won't even
swallow the WSDL much less construct a client so that I can test the
results.
As it turns out, it was DIME support that got me started on this thread.
Since .NET clients wouldn't swallow my DIMEd WSDLs, I started looking at the
MIMEd WSDLs. That's when I discovered the apachesoap:DataHandler type, which
I think is incorrect, and I suspect Anne agrees with me.

:
: 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:
