Small error in the previous post in regards to namespace, probably negligible, here's the SOAP response:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <soap:Body> <getStringsResponse xmlns="http://DefaultNamespace";> <out xmlns="http://DefaultNamespace";> <string>elem 1</string> <string>elem 2</string> </out> </getStringsResponse> </soap:Body> </soap:Envelope> Zarar Siddiqi wrote: > > Did some more work on this, I though it might be related to me exposing > the service via JSR 181 instead of through services.xml but thats not the > case (never made sense anyways). > > Even if I have the following very simple operation exposed, the client > fails to bind the returning collection into the ArrayOfString object.
