[Java] Parsing XML

[bermar]

ho questo file XML:

<?xml version="1.0" ?>
<product-catalog>
<product sku="123456" name="The Product">
<description locale="en_US">An excellent product.</description>
<description locale="es_MX">Un producto excellente.</description>
<price locale="en_US" unit="USD">99.95</price>
<price locale="es_MX" unit="MXP">9999.95</price>
</product>
</product-catalog>

e da validare con questo file XSD:

<xsd:schema
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element type="product-catalog"/>
<xsd:complexType name="productCatalog">
<xsd:element type="productType"
minOccurs="1"/>
</xsd:complexType>
<xsd:complexType name="productType">
<xsd:element name="description"
type="xsd:string" minOccurs="1">
<xsd:attribute name="locale"
type="xsd:string"/>
</xsd:element>
<xsd:element name="price"
type="xsd:decimal" minOccurs="1">
<xsd:attribute name="locale"
type="xsd:string"/>
<xsd:attribute name="unit"
type="xsd:string"/>
</xsd:element>
<xsd:attribute name="sku"
type="xsd:decimal"/>
<xsd:attribute name="name"
type="xsd:string"/>
</xsd:complexType>
</xsd:schema>

Al momento del parsing del file XML, la mia Servlet java mi restituisce il seguente errore:

Element type "product-catalog" is not declared in the dtd or schema.
org.xml.sax.SAXParseException: Element type "product-catalog" is not declared in the dtd or schema.

Qualcuno mi sa indicare dov'è il problema?
grazie!

il linguaggio va specificato anche nel titolo



ps: la prossima volta per rendere più leggibile il codice includilo nel tag [*code]..[*/code] (senza asterisco)
