[castor-dev] [XML] Unmarshalling an XML with 2 different namespaces inside leads to a SAXException

[Quenin Bertrand]

Hi

    I have a poblem with castor unmarshalling method. Let's be pragmatic and explain what i did exactly :

 

    I have the following schemas :

 

ImporteR.XSD:

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema targetNamespace="http://www.toto.com" xmlns:imported="http://imported.ns.com" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://www.toto.com">

<xs:import namespace="http://imported.ns.com" schemaLocation="imported.xsd"/>

<xs:element name="Personne">

<xs:complexType>

<xs:sequence>

<xs:element ref="tns:Nom"/>

<xs:element ref="tns:Prenom"/>

<xs:element name="Adresse" type="imported:AdresseType"/>

</xs:sequence>

</xs:complexType>

</xs:element>

<xs:element name="Nom" type="xs:string"/>

<xs:element name="Prenom" type="xs:string"/>

</xs:schema>

 

ImporteD.XSD:

<?xml version="1.0" encoding="UTF-8"?>

<xsd:schema targetNamespace="http://imported.ns.com" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<xsd:complexType name="AdresseType">

<xsd:all>

<xsd:element name="Numero" type="xsd:int"/>

<xsd:element name="TypeRue" type="xsd:string"/>

<xsd:element name="NomRue" type="xsd:string"/>

<xsd:element name="CodePostal" type="xsd:int"/>

<xsd:element name="Ville" type="xsd:string"/>

</xsd:all>

</xsd:complexType>

</xsd:schema>

 

These schema are processed successfully via Castor using the "type" class generation and the "generated imported schema types"  option.

 

Here is the code i used to generate Java implementations:

 

SourceGenerator sg = new SourceGenerator();
        try {
            Properties builderConfiguration = sg.getDefault();
            builderConfiguration.put("org.exolab.castor.builder.javaclassmapping", "type");
            sg.setGenerateImportedSchemas(true);
            sg.generateSource("importer.xsd", "input");
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

 

This results in correct Java classes generation in correct package.

 

I have generated a smaple XML file that respects these schema (I used the Personne element):

 

ImporteR.XML:

<?xml version="1.0" encoding="UTF-8"?>

<tns:Personne xmlns:tns="http://www.toto.com" xmlns:p="http://imported.ns.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.toto.com importer.xsd http://imported.ns.com imported.xsd ">

<tns:Nom>tns:Nom</tns:Nom>

<tns:Prenom>tns:Prenom</tns:Prenom>

<Adresse>

<Numero>0</Numero>

<TypeRue>TypeRue</TypeRue>

<NomRue>NomRue</NomRue>

<CodePostal>0</CodePostal>

<Ville>Ville</Ville>

</Adresse>

</tns:Personne>

 

Finally, I use the followinf code to unmarshall this XML into Personne classes:

        try {
            Personne personne = (Personne) Personne.unmarshalPersonne(new FileReader("importer.xml"));
        } catch (MarshalException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ValidationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

And i get this on the output console :

org.xml.sax.SAXException: unable to find FieldDescriptor for 'Nom' in ClassDescriptor of Personne

I really don't know how to correct this problem, i guess it's related with this XML containing more than one namespace ...

If anyone can help me solving this problem, i would be really pleased.
