I am using the XFire plugin wizard for Eclipse to create the proxy classes from
a .NET Web Service and am using JAXB.
AnnotationServiceFactory asf = new AnnotationServiceFactory( new
Jsr181WebAnnotations(), tm, new AegisBindingProvider(new
JaxbTypeRegistry()));
The proxy classes are generated fine. The problem I am having is that when the
XML
<soap:Body> <GetPersonResponse xmlns="urn:emp:service">
<GetPersonResult> <Name>Bob the Builder</Name> <Address
xsi:type="HomeAddress"> <HouseNumber>987654 ELM STREET</HouseNumber>
</Address> </GetPersonResult> </GetPersonResponse> </soap:Body>
is parse, the Address field should be instantiating a HomeAddress type which is
aderived type of Address.
I have tracked the problem to
com.sun.xml.bind.v2.runtime.unmarshaller.StAXStreamConnector
where there is a method private void handleStartElement() in which ncCount is
being set to
0 (zero)
// start namespace bindings int nsCount =
staxStreamReader.getNamespaceCount();
which causes the next block of code to not run
for (int i = 0; i < nsCount; i++) {
visitor.startPrefixMapping(
fixNull(staxStreamReader.getNamespacePrefix(i)),
fixNull(staxStreamReader.getNamespaceURI(i))); }
Because this is not being done, I get an exception "Could not unmarshall type."
As a total hack, I add visitor.startPrefixMapping("", "urn:emp:service") to the
watch list, everything goes through just fine. I can start debugging over and
over all day long and this will continue to work. As soon as I remove this
from the watch list, I get the original exception again.
If I change the .NET Service to have the Service in one namespace and the data
in anothernamespace, the following XML is generated
<soap:Body> <GetPersonResponse xmlns="urn:emp:service">
<GetPersonResult xmlns="urn:emp:data"> <Name>Bob the Builder</Name>
<Address xsi:type="HomeAddress"> <HouseNumber>987654 ELM
STREET</HouseNumber> </Address> </GetPersonResult>
</GetPersonResponse> </soap:Body>
the only difference between this and the XML above is the addition of
xmlns="urn:emp:data" on <GetPersonResult>.
when I get to handleStartElement() again nsCount is 1 and the code goes through
without incident.
I am publishing this information in an effort to solicit help in finding the
solutionas I am a .NET developer and not a Java developer. Getting to this
point has consumeda lot of time and any help in resolving this would greatly be
appreciated.
If you are interested, I can send the source code directly or you can get it
off of myblog: http://webbertsolutions.spaces.live.com/
