Hi friends, I am facing problem with parsing xml against schema using SAX2Parser with Xerces. I have created the xml file which has the following structure <?xml version="1.0" encoding="UTF-8"?> <Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="C:\SchemaValidation\testschema.xsd"> <RoleNo>XI-12</RoleNo> <Age>12</Age> </Person> Its corresponding schema is <?xml version="1.0"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name ="Person"> <xsd:complexType> <xsd:sequence > <xsd:element name="RoleNo" type="xsd:string" /> <xsd:element name="Age" type="xsd:short"/> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:schema> When I run the application to parse and validate, it checks for well-formedness correctly but does not validate against the schema. Instead gives the following error message: Element Type "Person" must be declared. Attribute "xsi:noNamespaceSchemaLocation" must be declared for element type "Person". Element Type "RoleNo" must be declared. Element Type "Age" must be declared. I have the following XMLReader parser; parser = new SAXParser(); 1. parser.setFeature( "http://xml.org/sax/features/validation", true); parser.setErrorHandler(new ValidityErrorReporter()); -------------->ValidityErrorReporter is my errorhandler class. COULD NOT GET THROUGH BY THIS METHOD. 2.Tried to set the property by parser.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",parser.getProperty("http://apache.org/xml/properties/schema/external-noNamespaceSche maLocation")); The method getProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation") is not able to recognise the property "external-schemaLocation " and "external-noNamespaceSchemaLocation". Please respond to my query as soon as possible. Thanks & Regards

Hi! I get exactly the same type of error when running the examples that come with xerces. And I have no idea why it's happening....
Check the following thread: http://www.javaranch.com/ubb/Forum31/HTML/000931.html Also, try to put your schema file in your web folder and try to change your xml like this: <Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://localhost/testschema.xsd">

Hi, Thanks for your response. I tried it like you said and placed both documents under wwwroot but I get exactly the same error. Xerces can't find the schema and I don't know where to put it!
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
