Choosing Your Parser Implementation

If no other factory class is specified, the default SAXParserFactory class is used. To use a parser from a different manufacturer, you can change the value of the environment variable that points to it. You can do that from the command line:

java -Djavax.xml.parsers.SAXParserFactory=yourFactoryHere ... 

The factory name you specify must be a fully qualified class name (all package prefixes included). For more information, see the documentation in the newInstance() method of the SAXParserFactory class.
