Error validating xml schema

Question

Hi,
I'm getting an error trying to validate an xml document using xml schema(xsd). The java code/schema/xml/error are listed below.
Not sure what the error
" Invalid content was found starting with element 'ticker'. One of '{ticker}' is expected." means.
Using jre 1.6
Any input appreciated.
Thanks !
// Java Code
     SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
     Schema schema = sf.newSchema(schemaURL);
     Validator validator = schema.newValidator();
     validator.validate(new StreamSource(is));
// Schema
<xs:element name="stocktrade">
<xs:complexType>
<xs:sequence>
     <xs:element name="ticker" type="xs:string"/>
     <xs:element name="price" type="xs:string"/>
     <xs:element name="quantity" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
// XML doc
<stocktrade
xmlns ... and other attributes
>
<ticker>aaa</ticker>
<price>23.5</price>
<quantity>11</quantity>
</stocktrade>
// Error
Exception in thread "main" org.xml.sax.SAXParseException: cvc-complex-type.2.4.

When I tried this with Xerces SAX, I got---
org.xml.sax.SAXNotRecognizedException: http://java.sun.com/xml/jaxp/properties/schemaLanguage
Maybe Xerces has not implemented the schemaLanguage property.
I have been successfully using Xerces-dependent properties to do validation:
XMLReader parser = saxParser.getXMLReader();
parser.setFeature( "http://xml.org/sax/features/validation", true);
parser.setFeature( "http://xml.org/sax/features/namespaces", true);
parser.setFeature( "http://apache.org/xml/features/validation/schema", true);
parser.setFeature( "http://apache.org/xml/features/validation/schema-full-checking", true);
if (noNamespaceSchemaLocation!=null) {
parser.setProperty(
"http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
noNamespaceSchemaLocation);
if (schemaLocation!=null) {
parser.setProperty(
"http://apache.org/xml/properties/schema/external-schemaLocation",
schemaLocation);
Also, as DrClap pointed out, for the schema location I use URIs.
Please let me know if you got the jaxp schemaLocation property to work and how you did it.
