include schemas in JAXB beta

843834Nov 11 2002 — edited Nov 19 2002
Hi I am using <xsd:include> in my xsd file to refer to elements defined in another xsd.

When I compiled my xsd, xjc complains:
parsing a schema...
src-include.0: Failed to read included schema document 'COS.xsd'.
line 5 of Payment.xsd

src-resolve: Cannot resolve the name 'InstructionKeyInfo' to a(n) >elment declaration component.
line 29 of Payment.xsd

Failed to parse a schema.
Does JAXB 1.0 supports xsd:include?

Thanks!

Joe

My xsd:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema version="$Id$" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb" >

<xsd:include schemaLocation="COS.xsd"/>
<xsd:annotation>
<xsd:appinfo>
<jxb:globalBindings
fixedAttributeAsConstantProperty="true"
collectionType="java.util.Vector"
typesafeEnumBase="xsd:NCName"
choiceContentProperty="false"
typesafeEnumMemberName="generateError"
modelGroupAsClass="false"
enableFailFastCheck="false"
generateIsSetMethod="false"
underscoreBinding="asCharInWord">

</jxb:globalBindings>
<jxb:schemaBindings>
<jxb:package name="com.hsbc.gib.tools.cos.beans"/>
</jxb:schemaBindings>
</xsd:appinfo>
</xsd:annotation>

<xsd:element name="PaymentInstructionReq">
<xsd:complexType>
<xsd:sequence>
<xsd:element ref="InstructionKeyInfo" minOccurs="0" maxOccurs="1"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>


</xsd:schema>

It doesn't itself, but since you can feed jaxb a DOM document from any source, you can always use a processor that does support xinclude and feed the result to the unmarshaller. Try this:

(1) Get the XInclude Engine at http://xincluder.sourceforge.net/

(2) build the xinclude document with something like:


DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware( true );
factory.setCoalescing( true );
DocumentBuilder parser = factory.newDocumentBuilder();
InputSource input = new InputSource();
input.setByteStream( new FileInputStream( fname ) );
Document masterDoc = parser.parse( input );
Document doc = DOMXIncluder.merge( masterDoc, input.getSystemId() );

(3) then unmarshal the document with:

JAXBContext jc = JAXBContext.newInstance( "my.context" );
Unmarshaller u = jc.createUnmarshaller();
MyClass x = (MyClass) u.unmarshal( doc );

there's probably a faster Sax equivalent of this. Also works (better) with Castor.

hope this helps,

Oops! sorry: looking at it again, I see I misread your question. I thought you meant using xinclude in a datafile (which I'd just worked out how to do) rather than in a schema (which I haven't worked out). Apologies.

Yes. JAXB 1.0 supports included and imported schemas.
Can you please attach the COS.xsd too
