XSD Tutorials - Herong's Tutorial Examples - Version 5.11, by Dr. Herong Yang
Running XMLReaderValidator with Xerces2 2.11.0 Beta
This section describes a tutorial example on how to the Xerces2 XMLReader class to validate an XML document assigned with an XSD file with 'Xerces2 2.11.0 (XML Schema 1.1) (Beta)' version.
Now I am ready to test the "Xerces2 2.11.0 (XML Schema 1.1) (Beta)" version, with the same program, XMLReaderValidator:
c:\Progra~1\Java\jdk1.7.0_07\bin\java -cp ".;c:\local\xerces-2_11_0-xml-schema-1.1-beta\xercesImpl.jar" XMLReaderValidator dictionary_invalid_xsd.xml Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/wst/xml/xpath2/processor/XPathParserException at org.apache.xerces.impl.xs.traversers.XSDHandler.createTravers... at org.apache.xerces.impl.xs.traversers.XSDHandler.prepareForTra... at org.apache.xerces.impl.xs.traversers.XSDHandler.parseSchema(U... at org.apache.xerces.impl.xs.XMLSchemaLoader.loadSchema(Unknown ... at org.apache.xerces.impl.xs.XMLSchemaValidator.findSchemaGramma... at org.apache.xerces.impl.xs.XMLSchemaValidator.handleStartEleme... at org.apache.xerces.impl.xs.XMLSchemaValidator.startElement(Unk... at org.apache.xerces.impl.XMLNSDocumentScannerImpl.scanStartElem... at org.apache.xerces.impl.XMLNSDocumentScannerImpl$NSContentDisp... at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$Fragmen... at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDoc... at org.apache.xerces.parsers.XML11Configuration.parse(Unknown So... at org.apache.xerces.parsers.XML11Configuration.parse(Unknown So... at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Sou... at XMLReaderValidator.main(XMLReaderValidator.java:24) Caused by: java.lang.ClassNotFoundException: org.eclipse.wst.xml.xpath2.processor.XPathParserException at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) ... 16 more
I am surprised to see this ClassNotFoundException error. But it is not hard to fix it. The missing class is actually provided in org.eclipse.wst.xml.xpath2.processor_1.1.0.jar in the "Xerces2 2.11.0 (XML Schema 1.1) (Beta)" package.
Rerunning XMLReaderValidator with org.eclipse.wst.xml.xpath2.processor_1.1.0.jar included in the classpath, I get the correct validation result:
c:\Progra~1\Java\jdk1.7.0_07\bin\java -cp ".;c:\local\xerces-2_11_0-xml-schema-1.1-beta\xercesImpl.jar; c:\local\xerces-2_11_0-xml-schema-1.1-beta \org.eclipse.wst.xml.xpath2.processor_1.1.0.jar" XMLReaderValidator dictionary_invalid_xsd.xml Error: Public ID: null System ID: file:///C:/herong/dictionary_invalid_xsd.xml Line number: 7 Column number: 22 Message: cvc-datatype-valid.1.2.1: 'yes' is not a valid value for 'boolean'. ...
