Wolfgang,

Thanks for your quick feedback - setting target namespace to null works!


I am not quite sure what
" target namespace of a schema should match with the instance document"
means.
Can you please send a p2pio.xsd that will work with w3c example at
http://dsd.lbl.gov/nux/api/nux/xom/pool/BuilderFactory.html

Here are example files for a version with namespaces and another version without namespaces:

The target namespace of a schema should match with the instance
document. With your generated schema, try this:

String targetNamespace = null;
schemaLocations.put(new File("/tmp/p2pio.xsd"), targetNamespace);

Hello,

I am just trying to use the xml schema validation example from
http://dsd.lbl.gov/nux/api/nux/xom/pool/BuilderFactory.html
----------modified source code----------- // W3C XML Schema validation

Map schemaLocations = new HashMap(); schemaLocations.put(new
File("/tmp/p2pio.xsd"), "http://dsd.lbl.gov/ p2pio-1.0"); Builder
builder = new BuilderFactory().createW3CBuilder (schemaLocations);
Document doc = builder.build(new File("/tmp/p2pio.xml"));
System.out.println(doc.toXML()); ----------end of modified source code

----------

I am getting the following error:
nu.xom.ValidityException: cvc-elt.1: Cannot find the declaration of
element 'receive'. at line 1, column 24 in file:///C:/tmp/p2pio.xml
at nu.xom.Builder$ValidityRequired.error(Builder.java:1260)
at ...

I also couldn't find a matching p2pio.xsd so I generated one:
----------
<?xml version="1.0" encoding="UTF-8"?> <xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema";
elementFormDefault="qualified">
<xs:element name="receive">
<xs:complexType>
<xs:sequence>
<xs:element ref="transactionID"/>
<xs:element ref="min"/>
<xs:element ref="max"/>
<xs:element ref="timeout"/>
</xs:sequence>
<xs:attribute name="mode" use="required" type="xs:NCName"/>
</xs:complexType>
</xs:element>
<xs:element name="transactionID" type="xs:string"/>
<xs:element name="min" type="xs:integer"/>
<xs:element name="max" type="xs:integer"/>
<xs:element name="timeout" type="xs:NMTOKEN"/> </xs:schema>

TIA,
Radu
