Just to confuse matters further I realised the reason I could get a response
using your code is that it was using the "application/json/badgerfish"
MESSAGE_TYPE when in fact in my axis2.xml config my
JSONBadgerfishMessageFormatter/JSONBadgerfishOMBuilder are defined as using
"text/javascript". So in fact with your code I was sending plain XML, not
JSON. When I change it to "text/javascript" I get an exception and no
output:
Caused by: java.lang.IllegalArgumentException: The MessageContext does not
have an associated SOAPFault.
My client code is:
ServiceClient client = new
ServiceClient(ConfigurationContextFactory.createConfigurationContextFromFileSystem(null,"axis2.xml"),
null);
Options options = client.getOptions();
options.setProperty(Constants.Configuration.MESSAGE_TYPE,"text/javascript");
client.setTargetEPR(new
EndpointReference("http://mooshup.com/services/samples/RESTSample/getWeather";));
try {
OMElement payload =
AXIOMUtil.stringToOM("<getWeather><city>col</city></getWeather>");
OMElement omElement = client.sendReceive(payload);
omElement.serialize(System.out);
} catch (XMLStreamException e) {
e.printStackTrace();
}
So I am still very stuck!
