In org.apache.ode.bpel.compiler.wsdl.WSDLFactoryBPEL20 the custom serializers are not registered. Although the deserializers are:

public ExtensionRegistry newPopulatedExtensionRegistry()

{ ExtensionRegistry extRegistry; extRegistry = super.newPopulatedExtensionRegistry(); extRegistry.registerDeserializer(Definition.class, new QName(_propNS, "property"),_bs); extRegistry.registerDeserializer(Definition.class, new QName(_propNS, "propertyAlias"), _bs); extRegistry.registerDeserializer(Types.class, XMLSchemaType.QNAME, new XMLSchemaTypeSerializer()); extRegistry.registerDeserializer(Definition.class, new QName(_plnkNS, "partnerLinkType"),_bs); // TODO: register serializer as well return extRegistry; }
