public static SAXParserFactory newInstance()
SAXParserFactory. This
 static method creates a new factory instance
 This method uses the following ordered lookup procedure to determine
 the SAXParserFactory implementation class to
 load:

 implementation class with the key being the system property defined
 above.
 
 The jaxp.properties file is read only once by the JAXP implementation
 and it's values are then cached for future use.  If the file does not exist
 when the first attempt is made to read from it, no further attempts are
 made to check for its existence.  It is not possible to change the value
 of any property in jaxp.properties after it has been read for the first time.

 SAXParserFactory it can use the factory to
 configure and obtain parser instances.
 
 
 
 Setting the jaxp.debug system property will cause
 this method to print a lot of debug messages
 to System.err about what it is doing and where it is looking at.

false.
 
 Note that "the validation" here means a validating parser as defined in the XML recommendation. In other words, it essentially just controls the DTD validation. (except the legacy two properties defined in JAXP 1.2. See here for more details.)
 To use modern schema languages such as W3C XML Schema or
 RELAX NG instead of DTD, you can configure your parser to be
 a non-validating parser by leaving the setValidating(boolean)
 method false, then use the setSchema(Schema)
 method to associate a schema to a parser.

Sets the particular feature in the underlying implementation of org.xml.sax.XMLReader. A list of the core features and properties can be found at http://www.saxproject.org/
All implementations are required to support the XMLConstants.FEATURE_SECURE_PROCESSING feature.
 When the feature is
true: the implementation will limit XML processing to conform to implementation limits.
     Examples include entity expansion limits and XML Schema constructs that would consume large amounts of resources.
     If XML processing is limited for security reasons, it will be reported via a call to the registered
     ErrorHandler.fatalError(SAXParseException exception).
     See SAXParser parse methods for handler specification.
   false, the implementation will processing XML according to the XML specifications without
     regard to possible implementation limits.

      is created.java.lang.UnsupportedOperationException - For backward compatibility, when implementations for
      earlier versions of JAXP is used, this exception will be
      thrown.public void setSchema(Schema schema)
Set the Schema to be used by parsers created
 from this factory.
When a Schema is non-null, a parser will use a validator
 created from it to validate documents before it passes information
 down to the application.
When warnings/errors/fatal errors are found by the validator, the parser must
 handle them as if those errors were found by the parser itself. 
 In other words, if the user-specified ErrorHandler
 is set, it must receive those errors, and if not, they must be
 treated according to the implementation specific
 default error handling rules.
 
 
A validator may modify the SAX event stream (for example by adding default values that were missing in documents), and a parser is responsible to make sure that the application will receive those modified event stream.
Initially, null is set as the Schema.
This processing will take effect even if
 the isValidating() method returns false.
 
 
It is an error to use
 the http://java.sun.com/xml/jaxp/properties/schemaSource
 property and/or the http://java.sun.com/xml/jaxp/properties/schemaLanguage
 property in conjunction with a non-null Schema object.
 Such configuration will cause a SAXException
 exception when those properties are set on a SAXParser.
 A parser must be able to work with any Schema
 implementation. However, parsers and schemas are allowed
 to use implementation-specific custom mechanisms
 as long as they yield the result described in the specification.
