Thanks.
You can attach, access, or remove attachments belonging to a message using the org.apache.axis2.context.MessageContext in this API. Alternatively, you can also get a reference to the attachment map to directly manipulate the attachments.
Can I get to the MessageContext from the service's implementation object, e.g. MyServiceSoapBindingImpl?
Or, is the only way to touch the SOAP message is to "hand-write" it with the javax.xml.soap package?
