since I dropped the target namespace from the schema document it still works. But if there is a posibility to get it working with changing only the coding in saveRequest and not changing xml, it will be better? =========================== Code: =========================== public boolean saveRequest(String userID, InputStream request) { Boolean ok = false; SAXBuilder builder = new SAXBuilder(); builder.setEntityResolver(new NoOpEntityResolver()); try { Calendar calendar = Calendar.getInstance(); java.text.DateFormat df = new java.text.SimpleDateFormat("yyyyMMddHHmmss"); String timestamp = df.format(calendar.getTime()); String filename = this.xmlrequestpath + "/" + userID + "_REQUEST_" + timestamp + ".xml"; this.requestDoc = builder.build(request); this.writeToFile(this.requestDoc, filename); SAXBuilder builderValidator = new SAXBuilder("org.apache.xerces.parsers.SAXParser", true); builderValidator.setFeature( "http://apache.org/xml/features/validation/schema", true); builderValidator.setProperty( "http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation", "http://localhost:8080/EDIWheel/requests/" + this.requestDoc.getRootElement().getName() + ".xsd"); builderValidator.setValidation(true); this.requestDoc = builderValidator.build("http://localhost:8080/EDIWheel/requests/" + userID + "_REQUEST_" + timestamp + ".xml"); ok = true; // Fehler werden abgefangen und ausgegeben. } catch (IOException e) { System.out.println("I/O Error: " + e.toString()); } catch (JDOMException e) { System.out.println("Corrupted file, because of: " + e.getMessage()); } return ok; } =========================== Head of shema: =========================== <?xml version="1.0" encoding="UTF-8"?> <xsd:schema xmlns:ew="http://www.reifen.net" xmlns:px="http://www.reifen.net/Core" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:import namespace="http://www.reifen.net/Core" schemaLocation="inquiry_A2_reifen.net_Core.xsd"/>
