RE: XML validation using schema. May be off topic with SOAP

[Christer Holm�r]

You need to set the EntityResolver of your parser.   See http://xml.apache.org/xerces-j/apiDocs/org/xml/sax/EntityResolver.html   For example:   org.xml.sax.EntityResolver myResolver = new MyResolver(); String namespaceURI = "http://www.comp.com/mynamespace";    // The namespace identifier String schema; // Get the schema definition from the DB or let the resolver itself do it myResolver.addMapping(namespaceURI, schema); parser.setEntityResolver(myResolver);   Hope this helps!   /Christer -----Original Message----- From: Praveen Peddi [mailto:[EMAIL PROTECTED]] Sent: den 15 januari 2003 21:26 To: [EMAIL PROTECTED] Subject: XML validation using schema. May be off topic with SOAP I want to validate an xml document with an existing schema. I know there is a code to do it when the schema is present as a URL. BUt in my case schema is present with in the application (since it is stored in the database) and that is not the url. I have the following code: public static void DOMValidate(String XMLfile, String Schema){   long startTime = System.currentTimeMillis();                  // Instantiate the DOM parser.         DOMParser parser = new DOMParser();           // set the features         try{             parser.setFeature("http://xml.org/sax/features/namespaces",true);             parser.setFeature("http://xml.org/sax/features/validation", true);             parser.setFeature("http://apache.org/xml/features/validation/schema",true);             parser.setFeature("http://apache.org/xml/features/validation/schema-full-checking",true);             // convert the xml file name to a URL             String SystemId = null;             try{                 SystemId = new File(Schema).toURL().toExternalForm();             } catch(java.net.MalformedURLException ex){                 //ex.printStackTrace();                 log.error(ex);             }             parser.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",SystemId);             // myErrorHandler is a descendant of ErrorHandler, it should be set here to be able to catch parse errors             parser.setErrorHandler(new SchemaErrorHandler());           } catch (SAXNotSupportedException ex){             System.out.println("SAXNotSupportedException Exception");         } catch (SAXNotRecognizedException ex){                 System.out.println("SAXNotRecognizedException Exception");         }           // parse the xml file, the errorhandler class has callbacks,         // so those will be called automatically there is a parse error         try{                 parser.parse(new File(XMLfile).toURL().toExternalForm());                 //System.out.println("Parsed Successfully by DOM Parser");         } catch (org.xml.sax.SAXException ex){                 //System.out.println("SAXException Exception");                 //ex.printStackTrace();             log.error(ex);         } catch (java.io.IOException ex){                 System.out.println("IOException Exception");    } finally {    long endTime = System.currentTimeMillis();          //System.out.println("Total time of DOMValidate:"+(endTime-startTime));    }       }   How can I do the validation if the Schema is the actual schema string not the url. This looks like a common problem. I assume that its not universal that schema is not always stored externally.   Any suggestions are appreciated.   Praveen
