This is a legitimate question. The attachment sample is a DII (dynamic invocation) sample for good reason. AXIS doesn't yet support attachments in WSDL. I believe it MUST before AXIS 1.0 is released, but how soon that happens is unknown.

Hi. Forgive me if this has already been asked and answered. I looked through the archives, but could not find what I was looking for. I'm kinda new to all this, so forgive me if this is a silly question. I'm looking at the attachments example, and I'm wondering about the generated WSDL (i.e., the WSDL received when looking at http://host/services/urn:EchoAttachmentService?wsdl). Can someone help me understand how this WSDL would allow someone to understand that an attachment is expected as a request parameter and as the response? Shouldn't <mime:multipartRelated> be included in the <wsdl:binding> element? As a related question, how would someone determine what the request/response types are from this WSDL? It seems like this WSDL assumes that both client and server implicitly understand what a tns1:DataHandler is. Basically, I'm trying to understand how I can write web services that accept Files/InputStreams (i.e., DataHandlers) or respond with File objects. I don't want to be required to generate the client side stubs because I don't want to limit what environments (e.g., Java, Perl, etc.) can be used to access these services. Furthermore, I don't particularly want to be required to document what kind of custom serializers/deserializers are needed unless it's absolutely necessary. The JAXRPC spec, for example, seems to state that JAXRPC will take care of serialization issues to/from DataHandlers (see Section 7). Am I taking the wrong approach here by trying to use SOAP 1.1 w/ Attachments? Should I just return file objects as Base64 strings and allow the client to do what they want with it? Any thoughts are appreciated. Cheers, --Doug
