Extensible XML - Nesting Custom tags within custom tags

[hareshp]

I am having trouble with the example in Appendix B: http://static.springframework.org/sp...sible-xml-meat

I have created my own namespace with custom elements, but i am not able to nest the elements within each other. My goal is for my xml to look like this:

<itp:dateCell ....>
    <itp:dateCell  ..../>
    <itp:dateCell  ..../>
</itp:dateCell>

The error I am getting is:
org.xml.sax.SAXParseException: src-resolve.4: Components from namespace 'http://www.springframework.org/schema/itp' are not referenceable from schema document 'http://www.itpcorporation.com/schema/itp/itp.xsd'.

and its being referenced to the bold line in the schema below.


This is my Schema:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xsd:schema xmlns="http://www.springframework.org/schema/itp"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:beans="http://www.springframework.org/schema/beans"
    targetNamespace="http://www.itpcorporation.com/schema/itp"
    elementFormDefault="qualified"
    attributeFormDefault="unqualified">
    <xsd:import namespace="http://www.springframework.org/schema/beans"/>

    <xsd:element name="dateCell">
        <xsd:complexType>
            <xsd:complexContent>
                <xsd:extension base="beans:identifiedType">
                    <xsd:choice minOccurs="0" maxOccurs="unbounded">
                        <xsd:element ref="dateCell"/>
                    </xsd:choice>
                    <xsd:attribute .../>
                    <xsd:attribute .../>
                    <xsd:attribute .../>
                    <xsd:attribute .../>
                </xsd:extension>
            </xsd:complexContent>
        </xsd:complexType>
    </xsd:element>

I also have other elements in this schema and when i take dateCell out, i do not get any errors, but i am not able to nest.

The only difference between my code and the code in the example from the spring documentation is that the class I am trying to nest has a setter method for the List type. Because of this, i modified the code in the factory bean for method getObject() to look like this:

    public Object getObject() throws Exception
    {
        this.parent.setAuxiliaryList(children);
        return this.parent;
    }

I really need help understanding whats wrong with my code and/or approach. Thanks.

You seem to be a little schizophrenic about http://www.itpcorporation.com/schema and http://www.springframework.org/schema. If you choose one and stick to it your example should work - the xsd has references to both.

Thanks Dave. I am not getting that error anymore.
