∟Outdated: Running XMLReaderValidator with Xerces2 2.11.0 Beta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:

herong> 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:

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. You can all all JAR files from the Xerces2 package to the classpath to avoid any ClassNotFoundException errors.

Rerunning XMLReaderValidator with org.eclipse.wst.xml.xpath2.processor_1.1.0.jar included in the classpath, I get the correct validation result:

herong> 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'.
