Re: About dynamically create Type mapping to xml schema

[grovecai]

Hi Sebastian,

I don't have any special solution, but I did make some  attempts. I 
instantiate two DataObjects with type of "PurchaseOrder" from the two 
schema mentioned before, one for each. When using the getter and setter 
accessories to access the DataObjects, I found they are compatible. 
Thus, it satisfies my requirement, I don't need to stuck at mapping to 
early xml schema.

Hi grovecai,

Here's another quote from section "9.7 XSD Mapping Details":

"Model Groups (sequence, all, choice, group) do not contribute to the 
mapping

except for maxOccurs>1 results in Properties with many=true"

I'd be interested to know what your solution looks like now. Can you 
share?

The disappearance of the type attribute is mysterious. In section "9.4 
Mapping of XSD Built in Data Types" the spec says:

"If the XSD type of the instance value cannot be determined, or the 
SDO Type's instance class is java.lang.Object or null,

the value is read as a String." So this could perhaps be a bug.

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

    Hi, guys

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

    <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
    <http://www.w3.org/2001/XMLSchema>
    xmlns="http://example.com/IPO"; <http://example.com/IPO>
    targetNamespace="http://example.com/IPO"; <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";
    <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"; <http://example.com/IPO>
    xmlns:xs="http://www.w3.org/2001/XMLSchema";
    <http://www.w3.org/2001/XMLSchema>
    attributeFormDefault="qualified" elementFormDefault="qualified"
    targetNamespace="http://example.com/IPO"; <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!
