The name of the property is "http://apache.org/xml/properties/schema/external-schemaLocation";. You capitalized the 's' on schemaLocation. That's why it wasn't recognized. > Here is my code : > > System.setProperty("javax.xml.validation.SchemaFactory:http://www. > w3.org/2001/XMLSchema","org.apache.xerces.jaxp.validation.XMLSchemaFactory"); > System.setProperty("org.apache.xerces.xni.parser.XMLParserConfiguration", > "org.apache.xerces.parsers.IntegratedParserConfiguration"); > String language = XMLConstants.W3C_XML_SCHEMA_NS_URI; > > SAXParserFactory spf = SAXParserFactory.newInstance(); > spf.setValidating(true); > spf.setNamespaceAware(true); > spf.setFeature("http://apache.org/xml/features/validation/schema";, true); > > parser = spf.newSAXParser(); > > XMLReader xmlReader = parser.getXMLReader(); > xmlReader.setProperty("http://apache.org/xml/properties/external- > SchemaLocation","http://ltsc.ieee.org/xsd/LOM http://ltsc.ieee. > org/xsd/lomv1.0/lomLoose.xsd"); > > Thanks a lot in advance for you help ! If you're just starting to write your application I'd suggest using the JAXP Valdation API [1] instead of the Xerces specific features and properties. You'll get better performance (from the grammar caching) and more portable code. Should also avoid setting the "org.apache.xerces.xni.parser.XMLParserConfiguration" system property to something other than the current default (or one that extends the default) unless you have a specific reason to do so. "org.apache.xerces.parsers.IntegratedParserConfiguration" is ancient and doesn't support many of the features introduced in recent releases. > greetings, > Bram Vandeputte > > > -- > Bram Vandeputte > > Katholieke Universiteit Leuven > Dept.
