XML XSD Validation

[Rajeevr]

Hi,

I am using Xerces for validating a XML against a XSD. Xsd validation can be done by two ways: noNamespaceSchemaLocation/schemaLocation.
1
I successfully validated it against XSD by using noNamespaceSchemaLocation like this:

<?xml version="1.0"?>
<dictionary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:noNamespaceSchemaLocation="c:/dictionary.xsd">

2
But I am facing problem in schemaLocation. When I provide schemaLocation which is well accessible and available in my local machine, Xerces throws this error: cvc-elt.1: Cannot find the declaration of element 'dictionary'. I put dictionary.xsd file under tomcat and started the tomcat server. But

<?xml version="1.0"?>
<dictionary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                        xsi:schemaLocation="http://localhost:8080/a1/ http://localhost:8080/a1/dictionary.xsd">


XSD File;
<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <xsd:element name="dictionary" type="dictionaryType"/>
        <xsd:complexType name="dictionaryType">
                <xsd:sequence>
                        <xsd:element name="word" type="wordType" maxOccurs="unbounded"/>
                </xsd:sequence>
        </xsd:complexType>
……………
……………

Someone please help me out to understand the exact problem.

Regards,
Rajeev

As I see it your XML vocabulary doesn't use a
namespace, thus xsi:noNamespaceSchemaLocation is
working just fine as expected.  You can't expect
the xsi:schemaLocation to work when you aren't
using a namespace, because the namespace you are
naming in the attribute isn't a namespace that is being used.

The xsi:schemaLocation has an arbitrary number of
pairs of values, each pair being a namespace URI and a location URL:

    http://www.w3.org/TR/2004/REC-xmlschema-1-20041028/#schema-loc

Using this attribute is of no help if you aren't
using a namespace for your XML vocabulary.

I hope this helps.

Your dictionary element is in no namespace, so you should use
noNamespaceSchemaLocation.
