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. The SOAP
response is correct but when I try to access the list using the API
generated using the wsgen task, the list is always empty.
Has anybody actually got a Collection to return using a web service? I've
posted my complete configuration.
Here's the service class:
public Collection<String> getStrings() {
Collection<String> list = new ArrayList<String>();
list.add("elem 1");
list.add("elem 2");
return list;
}
Here's the services.xml:
<beans xmlns="http://xfire.codehaus.org/config/1.0";>
<service>
<name>StringService</name>
<serviceClass>StringService</serviceClass>
</service>
</beans>
Here's the sample client code:
Service serviceModel = new
ObjectServiceFactory().create(StringServicePortType.class);
StringServicePortType service = (StringServicePortType) new
XFireProxyFactory().create(serviceModel, SERVICE_URL);
ArrayOfString strings = service.getStrings();
System.out.println("strings = " + strings.getString().size()); // always
zero
Here's the response I captured using TCPMON:
<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://xfire.codehaus.org/BookService";>
<out xmlns="http://xfire.codehaus.org/BookService";>
<string>elem 1</string>
<string>elem 2</string>
</out>
</getStringsResponse>
</soap:Body>
</soap:Envelope>
