Hi,
We're attempting to move from using the Sun "Reference Implementation"
(JAX pack etc), to using Axis. I've been using the 1.1RC1 release.
Basically we have a system where a client makes a call to a server,
which implements a SOAP service using a JAXMservlet (basically an
extension of a HttpServlet, which replies to POST's by calling an
onMessage method). This constructs a reply by creating a SOAPMessage
(which in our case includes a number of attachments) and dumping this
reply back to the invoking client (using a SOAPMessage.writeTo()).
This all worked fine with the Sun reference implementation, but fails
horribly with Axis.
I've attached a simple piece of example code (which I'm running within
WebLogic, but should work in any servlet engine). This happily receives
a "multipart" SOAP message but fails to send anything sensible back as a
reply. However, if you remove the attachment from the reply then all is
fine, since it simply returns a simple xml document in that case.
Essentially what seems to happen is that suitable MimeHeaders are never
set/created when constructing a SOAPMessage under Axis, in particular
the rather crucial "Content-Type" is never set, so that the reply just
seems to be a streamed together set of attachment parts, which is
obviously unintelligible to the receiver.
Its not entirely clear if what we are doing _should_ work, although its
exactly along the lines of many of Sun's example codes, and its hard to
see what else could be done.
Anyone else tried doing something along these lines and have any
suggestions?
Regards,
Mark
