This is a nice solution. My implementation needs to reverse the roles. Instead of the client sending an attachment, my web service sends the attachment. My WSDL for the response looks like:
<wsdl:message name="composeRequest">
<wsdl:part type="apachesoap:Element" name="inputMeta" />
</wsdl:message>
<wsdl:message name="composeResponse">
<wsdl:part type="apachesoap:DataHandler" name="composedOutput" />
<wsdl:part type="xsd:string" name="outputMeta" />
</wsdl:message>
:
:
<wsdl:operation name="compose">
<wsdl:input message="intf:composeRequest" name="composeRequest" />
<wsdl:output message="intf:composeResponse" name="composeResponse" />
</wsdl:operation>
Can I just adjust my service operation's signature to be:
public void compose(Element reportRequest, DataHolder composedOutput, DataHolder outputMeta);
Is this doable?

I modified the code I got from Sameer Tyagi (Co-author
of Java Web Services Architecture) to make it work
under Java WSDP 1.3 tutorial build directory structure.
It contains code for sending an attachment as either
DataHandler or javax.xml.transform.Source object.
It can be obtained from (attachment.zip file)
