Hi Sebastian,

Thank you for your reply. 
I know how it works now. Have you notice that the element "items" in the schema generated by my code  lost its type attribute. Is this a bug?

Hello grovecai,

 

XSD sequences are model groups that may be flattened in the resulting SDO model.

Look at section “9.3.2 Mapping of XSD Elements” of the SDO 2.1.0 spec. It says:

 

Element in all, choice, or sequence

<[GROUP] maxOccurs=[G_MAX]>

<element name=[NAME]

type=[TYPE]

maxOccurs=[E_MAX] />

</[GROUP] >

where

[GROUP] = all, choice, sequence

• Element groups and model

groups are treated as if they

were expanded in place.

• A property is created for every element

many=true when E_MAX or G_MAX

is > 1

 

So I believe the result you’re getting is in accordance with the SDO spec, at least that’s how

I read the spec.

 

Best,

Sebastian

Subject: About dynamically create Type mapping to xml schema

 

Hi, guys

I need to dynamically create type mapping to the below schema:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://example.com/IPO"
targetNamespace="http://example.com/IPO">
    <xsd:element name="purchaseOrder" type="PurchaseOrder"/>
    <xsd:complexType name="PurchaseOrder">
        <xsd:sequence>
            <xsd:element name="shipTo" type="xsd:string" minOccurs="0"/>
            <xsd:element name="billTo" type="xsd:string" minOccurs="0"/>
            <xsd:element name="items" type="xsd:string" minOccurs="0" maxOccurs="unbounded"/>
        </xsd:sequence>
    </xsd:complexType>
</xsd:schema>

Here is my code:
       HelperContext helperContext = SDOUtil.createHelperContext();
        DataFactory df = helperContext.getDataFactory();
        DataObject typeDef = df.create("commonj.sdo", "Type");
        typeDef.set("uri", "http://example.com/IPO");
        typeDef.set("name", "PurchaseOrder");
       
        DataObject propDef = typeDef.createDataObject("property");
        propDef.set("name", "shipTo");
        propDef.set("type",
                helperContext.getTypeHelper().getType("commonj.sdo", "String"));
       
        propDef = typeDef.createDataObject("property");
        propDef.set("name", "billTo");
        propDef.set("type",
                helperContext.getTypeHelper().getType("commonj.sdo", "String"));
       
        propDef = typeDef.createDataObject("property");
        propDef.set("name", "items");
        propDef.set("type",
                helperContext.getTypeHelper().getType("commonj.sdo", "String"));
        propDef.set("many", true);
       
        Type type  = helperContext.getTypeHelper().define(typeDef);
        List types = new ArrayList<Type>();
        types.add(type);
       
        System.out.println(helperContext.getXSDHelper().generate(types));


The created type actually map to the below schema:

<xs:schema xmlns:sdo="commonj.sdo" xmlns:sdoJava="commonj.sdo/java"
xmlns:stn_1="http://example.com/IPO" xmlns:xs="http://www.w3.org/2001/XMLSchema"
attributeFormDefault="qualified" elementFormDefault="qualified"
targetNamespace="http://example.com/IPO">
    <xs:complexType abstract="false" name="PurchaseOrder">
        <xs:sequence>
            <xs:element maxOccurs="unbounded" minOccurs="0" name="items"/>
        </xs:sequence>
        <xs:attribute name="shipTo" type="xs:string"/>
        <xs:attribute name="billTo" type="xs:string"/>
    </xs:complexType>
    <xs:element name="purchaseOrder" type="stn_1:PurchaseOrder"/>
</xs:schema>

What did I missed? I want "shipTo" and "billTo" to be elements contained in sequence, not as attribute contained directly in complexType. Any hint may be helpful. Thank you!

Grovecai
