parse web service response

[eunever32]

Hi

I am calling a web service directly via http because I'm using the
proxy gateway.

So instead of Object object = call.invoke(soapEnvelope)

I'm doing

HttpClient client
client.executeMethod(postMethod)
....
And then read the response into a string.

My question is:
When I examine the response I see:
------=_Part_7_21866603.1269262621509
Content-Type: text/xml; charset=UTF-8
Content-Transfer-Encoding: binary
Content-Id: <7CDE7D3D9A8ECEA3A8DDC9F2E22917BB>

<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope
xmlns:soapenv="http://
....
</soapenv:Envelope>

------=_Part_7_21866603.1269262621509--

Is there some API that I can use to cast the above into an object and
then obtain the soap response and attachment?

Thanks

As I see it you have two options:

1) Use a SOAP API for SOAP if you want SOAP-like processing of SOAP
objects. Search an archive of this newsgroup for recommendations. It
probably wouldn't hurt to try whatever SOAP API seems to be foremost in
your IDE. I'd be surprised if any SOAP API couldn't cope with a regular
HTTP-proxy (or a Socks proxy)

2) Use HttpClient if you are happy to parse the returned XML using an
XML parsing API - I'd use a DOM (not SAX) style API to parse the XML and
XPath to extract values but YMMV. Then construct your own objects from
the extracted set of values.

Approach 1 is the obvious one and I expect most people find it to be
easier (assuming you have WSDL, XSD etc).

Which SOAP (web-services) API had you tried and found to lack proxy support?

A reputable SOAP library will handle proxies. You don't have to do it
yourself.

Can you use Metro, aka the JAX-WS reference implementation, which comes as
part of the JDK for 1.6 onwards and is a separate download for 1.4 and
1.5? If you're starting from WSDL, you can; not sure whether you can if
you're not. Metro uses java's standard HttpConnection for its connections,
and that can use proxies; you configure this using system properties, or
some other mechanisms:

I would be very surprised if your web service toolkit does
not support proxies.

I really believe that you should use a web service toolkit to make
the call.

But even if not then I would expect a web service toolkit to
have some parsing classes that you can reuse in your code for
the SOAP part.

Only as last resort go to pure W3C DOM.

The attachment is easy. That is just taking everything between the
two blank lines and stuff it in a file.
