Hi, I am developing a simple generic (wsdl/schema-independent) SOAP message validatior class that uses Xerces. The problem I have is that I use an string based schema (not an URI nor a file) because I want to use WSDL's schema. The validation only works when an schema location is specified in the XML instance:
<fi:fish xmlns:fi="http://globalip:8080/fish"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://globalip:8080/fish http://192.168.82.29:8080/fisherWS/fish.xsd";> But I would like it to work without schema location: <fi:fish xmlns:fi="http://globalip:8080/fish";> I have been reading the Xerces doc (properties and features) and I coded the config in such a way: private String VALIDATION = "http://xml.org/sax/features/validation";; private String SCHEMA = "http://apache.org/xml/features/validation/schema";; private String SCHEMA_FULL_CHECKING = "http://apache.org/xml/features/validation/schema-full-checking";; private String WARN_ON_DUPLICATE_ATTDEF = "http://apache.org/xml/features/validation/warn-on-duplicate-attdef";; parser.setFeature(LOAD_EXTERNAL_DTD, true); parser.setFeature(VALIDATION, true); parser.setFeature(SCHEMA, true); parser.setFeature(SCHEMA_FULL_CHECKING, true); parser.setFeature(WARN_ON_DUPLICATE_ATTDEF, true); Thanks in advance, Pau The full source code is: import org.w3c.dom.*; import java.io.FileNotFoundException; import java.net.UnknownHostException; import org.w3c.dom.Element; import org.xml.sax.SAXParseException; import org.xml.sax.SAXException; import org.xml.sax.ErrorHandler; import org.xml.sax.helpers.XMLReaderFactory; import org.xml.sax.InputSource; import java.io.StringReader; import javax.xml.soap.SOAPBody; import org.xml.sax.XMLReader; import javax.xml.soap.SOAPEnvelope; import org.apache.axis.MessageContext; import org.apache.catalina.util.SchemaResolver; import org.xml.sax.helpers.DefaultHandler; import java.io.IOException; import org.apache.tomcat.util.digester.Digester; public class SOAPvalidator { private String VALIDATION = "http://xml.org/sax/features/validation";; private String SCHEMA = "http://apache.org/xml/features/validation/schema";; /** * String constant used for the schema full checking feature of the Xerces * parser. * * @build 10 */ private String SCHEMA_FULL_CHECKING = "http://apache.org/xml/features/validation/schema-full-checking";; /** * String constant used for the warn on duplicate attribute definition * feature of the Xerces parser. * * @build 10 */ private String WARN_ON_DUPLICATE_ATTDEF = "http://apache.org/xml/features/validation/warn-on-duplicate-attdef";; /** * String constant used for the warn on undeclared element definition * feature of the Xerces parser. * * @build 10 */ private String LOAD_EXTERNAL_DTD = "http://apache.org/xml/features/nonvalidating/load-external-dtd";; // Name of the parser to use to create the xmlReader.
