Deserializing object based on complexType when elements are present in schema [message #499195] Fri, 20 November 2009 11:24 Go to next message

I'm hoping someone can help me understand some behaviour I'm seeing. I'm not suggesting there's a bug here, I just don't fully grasp what's happening.

Consider this simple XML Schema:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://testing.com/hello" targetNamespace="http://testing.com/hello">
	<xs:complexType name="Car">
		<xs:sequence>
			<xs:element name="colour" type="xs:string"/>
		</xs:sequence>
	</xs:complexType>
</xs:schema>


Transforming to EMF, I have a class to represent Car.

I then instantiate my Car class and serialize it to XML with the following options (which are all necessary for various reasons for the system I'm working on):

XMLResource.OPTION_EXTENDED_META_DATA = Boolean.TRUE
XMLResource.OPTION_SAVE_TYPE_INFORMATION =  Boolean.TRUE
XMLResource.OPTION_KEEP_DEFAULT_CONTENT =  Boolean.TRUE
XMLResource.OPTION_ENCODING = "UTF-8"


This results in the following XML

<?xml version="1.0" encoding="UTF-8"?>
<hello:Car xmlns:hello="http://testing.com/hello">
  <colour>Purple</colour>
</hello:Car>


I then deserialize this with the following options set:

XMLResource.OPTION_EXTENDED_META_DATA = Boolean.TRUE		
XMLResource.OPTION_DEFER_ATTACHMENT =  Boolean.TRUE
XMLResource.OPTION_USE_PARSER_POOL = (my pool instance)
XMLResource.OPTION_USE_DEPRECATED_METHODS =  Boolean.FALSE


Deserialization gives me a Car object, just like the one I started with. Everything is fine so far.

I now alter my schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://testing.com/hello" targetNamespace="http://testing.com/hello">


	<xs:element name="myElement" type="xs:int"/>


	<xs:complexType name="Car">
		<xs:sequence>
			<xs:element name="colour" type="xs:string"/>
		</xs:sequence>
	</xs:complexType>
</xs:schema>


(i.e. I've added the 'myElement' declaration within the root)

If I repeat my serialization and deserialization, as I did before, then the serialization results in the same XML, but deserialization fails with:

org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'Car' not found. (, 2, 51)
	at org.eclipse.emf.ecore.xmi.impl.XMLHandler.reportUnknownFeature(XMLHandler.java:1976)
	at org.eclipse.emf.ecore.xmi.impl.XMLHandler.handleUnknownFeature(XMLHandler.java:1940)
	at org.eclipse.emf.ecore.xmi.impl.XMLHandler.handleFeature(XMLHandler.java:1884)
	at org.eclipse.emf.ecore.xmi.impl.XMLHandler.createDocumentRoot(XMLHandler.java:1443)
[snip]


I suspect there's a reasonable explanation for this, but my question is: Why does introduction of an element within the schema affect the way my object (derived from a complexType) is deserialized?

I've found that setting XMLResource.OPTION_EXTENDED_META_DATA = Boolean.FALSE makes the problem go away, but I'm not sure that's a solution as (a) We set that option to resolve earlier issues and (b) my EMF book tells me it's required for Ecore derived from XML Schema.

Any comments much appreciated.

Ben.

I'd like to add one further observation to my earlier post. If I add an element declaration to my schema, with exactly the same name as my complexType and set its type to my complexType, as follows:

	<xs:element name="Car" type="Car"/>


...then my serialized XML can be deserialized. As my element conveniently has the same name as my complexType, my XML can be deserialized based on it matching the element declaration. As the element has its type set to the complexType, everything matches up. Deserialization returns a DocumentRoot and calling getCar() gives me my car.

This probably isn't a solution though, as I'm not sure I can stipulate that the schema contains such an element. I'd also prefer my serialize/deserialize functions to be symmetrical.

Assuming I am able to influence the schema, I'd be interested to hear opinions on whether my solution would be considered a hack/abuse.

Cheers,
Ben.

In the absence of a DocumentRoot, the complex type's name will be used
to serialize the instance; unfortunately that doesn't actually conform
to the schema. And of course given your schema, there is no possible
conforming serialization because there are no global element declarations.

Now, because there is a document root, it notices that there is no Car

Because then it's more of an XMI type of serialization and document
roots have no special significance.

You really need a global element of a type that matches the type of
instance you want to serialize at the root. You might be interested in
this option and the corresponding one needed to deserialize:

/**
* When {@link #OPTION_EXTENDED_META_DATA} is used,
* this load option set to Boolean.TRUE will direct the
deserializer to suppress creating a document root instance.
* This option is typically used in combination with {@link
#OPTION_ELEMENT_HANDLER}.
* @since 2.4
*/
String OPTION_SUPPRESS_DOCUMENT_ROOT = "SUPPRESS_DOCUMENT_ROOT";

Thanks Ed.

The combination of OPTION_ELEMENT_HANDLER and OPTION_SUPPRESS_DOCUMENT_ROOT do the trick nicely.

Cheers,

Hello again.

As discussed above, I'm now using OPTION_ELEMENT_HANDLER on save. Consider this schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified" xmlns="http://example.com/extension" targetNamespace="http://example.com/extension">
	<xs:element name="CustomerElement" type="Customer"/>
	<xs:complexType name="Customer">
		<xs:sequence>
			<xs:element name="customerId" type="xs:string"/>
		</xs:sequence>
	</xs:complexType>
	<xs:complexType name="PersonalCustomer">
		<xs:complexContent>
			<xs:extension base="Customer">
				<xs:sequence>
					<xs:element name="personalId" type="xs:int"/>
				</xs:sequence>
			</xs:extension>
		</xs:complexContent>
	</xs:complexType>
	<xs:complexType name="BusinessCustomer">
		<xs:complexContent>
			<xs:extension base="Customer">
				<xs:sequence>
					<xs:element name="businessName" type="xs:string"/>
				</xs:sequence>
			</xs:extension>
		</xs:complexContent>
	</xs:complexType>
</xs:schema>


So, we have a Customer complex type acting as super-type to PersonalCustomer and BusinessCustomer. I've defined a single element, CustomerElement, of type Customer.

If I create a BusinessCustomer and serialize it, I get the following XML. ElementHandlerImpl can't find an exactly-matching feature in DocumentRoot to match BusinessCustomer, so walks up the hierarchy, hits Customer and ends up using a CustomerElement. The trouble is, in the absense of an xsi:type attribute on the root (I'm using OPTION_SAVE_TYPE_INFORMATION on save, but it has no effect here), there is no record of the fact a BusinessCustomer is being referenced as a Customer:

<?xml version="1.0" encoding="UTF-8"?>
<extension:CustomerElement xmlns:extension="http://example.com/extension">
  <extension:customerId>123</extension:customerId>
  <extension:businessName>Ringo Sammon</extension:businessName>
</extension:CustomerElement>


This won't validate against my schema and fails deserialization:

org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Feature 'businessName' not found. (, 4, 27)
	at org.eclipse.emf.ecore.xmi.impl.XMLLoadImpl.handleErrors(XMLLoadImpl.java:83)
	at org.eclipse.emf.ecore.xmi.impl.XMLLoadImpl.load(XMLLoadImpl.java:191)
	at org.eclipse.emf.ecore.xmi.impl.XMLResourceImpl.doLoad(XMLResourceImpl.java:180)
[snip]


If I alter the serialized XML as follow, it will then validate against my schema (I use XMLSpy for such validation) and deserialize correctly:

<?xml version="1.0" encoding="UTF-8"?>
<extension:CustomerElement xmlns:extension="http://example.com/extension" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:type="extension:BusinessCustomer">
  <extension:customerId>123</extension:customerId>
  <extension:businessName>Ringo Sammon</extension:businessName>
</extension:CustomerElement>


I realise that adding an element to my schema and making its type BusinessCustomer will resolve this, but looking at the source for ElementHandlerImpl, I got this impression that my scenario would be supported as-is.

Thanks in advance for any help.

Cheers,
Ben.

Ben,

Yes, it looks like at the top level, it's not doing any checking to see
if an xsi:type is needed. Perhaps you can create a good (failing) test
case and open a bugzilla with that.
