Sorry to bring this up again after so long but I've had some time now to play
with this again and I'm still having problems. I am able to form a sensible
looking JSON request containing my namespace and without. In EITHER case the
response from the server comes back with the namespace included:
{"ns:getMostActiveArtistResponse":{"@xmlns":{"ns":"http:\/\/NicksGigs.nsteel.qis.Nickcom.com"},"ns:return":{"$":"The
Cure"}}}
When I then do response.getChildElements(); I get the error "forceExpand:
expected element namespace getMostActiveArtistResponse, found " which then
throws the exception "Element namespace from data source is
http://NicksGigs.nsteel.qis.Nickcom.com, not the expected ".
All I'm doing on my Java client is:
OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace ns =
fac.createOMNamespace("http://NicksGigs.nsteel.qis.Nickcom.com","ns2";);
OMElement rootElement = fac.createOMElement("getMostActiveArtist", ns);
OMElement response = client.sendReceive(rootElement);
Iterator<OMElement> itr = response.getChildElements();
Which sends the request:
{"ns2:getMostActiveArtist":{"@xmlns":{"ns2":"http:\/\/NicksGigs.nsteel.qis.Nickcom.com"}}}
When tracing through it seems that the badgerfish receiver doesn't have a
correct record of the namespace, should I be setting it somewhere before I
send the request?
Thanks,
Nick
