Hi,
I've WebObjects Web Service applications exchanging objects throught
SOAP. I've registered both AXIS serializer and deserializer factories
on each application, just after the
ApplicationDidFinishLaunchingNotification notification (static
initialization fail).
On the Web Service server, my objects are correctly serialized. But on
the Web Service client side, an exception is always thrown:
Error during invocation org.xml.sax.SAXException: No deserializer for
{http://zks.net/webobjects/webservices/soap/}WSGenericRecord
com.webobjects.foundation.NSForwardException for AxisFault
faultCode: {http://xml.apache.org/axis/}Server.userException
faultString: org.xml.sax.SAXException: No deserializer for
{http://zks.net/webobjects/webservices/soap/}WSGenericRecord
faultActor: null
faultDetail:

Why? Both serializer seems correctly registered using this
com.webobjects.appserver.WOWebServiceRegistrar call:
WOWebServiceRegistrar.registerFactoriesForClassWithQName(
new WSGenericRecordSerializerFactory(),
new WSGenericRecordDeserializerFactory(),
WSGenericRecord.class,
WSGenericRecordSerialization.ClassQName);
Just to be sure, I've tested the registration status using
com.webobjects.appserver.WOWebServiceUtilities:
-
WOWebServiceUtilities.qNameForType(net.zks.wscontrol.WSGenericRecord.cla
ss, null) successfully returns the net.zks.wscontrol.WSGenericRecord
class reference;
-
WOWebServiceUtilities.typeForQName(net.zks.webservices.support.xml.WSGen
ericRecordSerialization.ClassQName, null) successfully returns the
"{http://zks.net/webobjects/webservices/soap/}WSGenericRecord"; AXIS
qualified name.
So what's the problem with deserializer registration? Does anyone here
have a clue or an advice? Or should I report this as a bug?
Thanks,
