SaxClassInfo.java - SAX Implementation Class
How to verify the SAX (Simple API for XML) implementation class information?
✍: FYIcenter
If you want to verify the SAX (Simple API for XML) implementation class information,
you can try the following example program:
// Copyright (c) 2017 FYIcenter.com import javax.xml.parsers.SAXParserFactory; import javax.xml.parsers.SAXParser; public class SaxClassInfo { public static void main(String[] args) throws Exception { SAXParserFactory f = SAXParserFactory.newInstance(); SAXParser p = f.newSAXParser(); System.out.println("SAX class info:"); System.out.println(" Factory: "+f.getClass().getName()); System.out.println(" Parser: "+p.getClass().getName()); } }
Compile and run it with Java SE 8 SDK:
>\fyicenter\jdk-1.8.0\bin\javac SaxClassInfo.java >\fyicenter\jdk-1.8.0\bin\java SaxClassInfo SAX class info: Factory: com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl Parser: com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl
Run it again with Apache Xerces 2.11.0 xercesImpl.jar provided:
>\fyicenter\jdk-1.8.0\bin\java -cp .;\fyicenter\xerces-2_11_0\xercesImpl.jar; SaxClassInfo SAX class info: Factory: org.apache.xerces.jaxp.SAXParserFactoryImpl Parser: org.apache.xerces.jaxp.SAXParserImpl
The output tells you that the default implementation of SAX in Java SE 8 JDK is the Apache Xerces 2.7.1 package. And you can override it with Apache Xerces 2.11.0 by specifiying the JAR file to the -cp option.
You can confirm Apache Xerces version numbers as desribed below:
>\fyicenter\jdk-1.8.0\bin\java com.sun.org.apache.xerces.internal.impl.Version Xerces-J 2.7.1 >\fyicenter\jdk-1.8.0\bin\java -cp .;\fyicenter\xerces-2_11_0\xercesImpl.jar org.apache.xerces.impl.Version Xerces-J 2.11.0
