/**
 * Using data in the systemSettings (this data typically originates in the pentaho.xml file), initialize 3 System
 * properties to explicitly identify the Transformer, SAX, and DOM factory implementations. (i.e. Crimson, Xerces,
 * Xalan, Saxon, etc.)/*from  www.  j  a v a 2s .  co  m*/
 * <p/>
 * For background on the purpose of this method, take a look at the notes/URLs below:
 * <p/>
 * Java[tm] API for XML Processing (JAXP):Frequently Asked Questions http://java.sun
 * .com/webservices/jaxp/reference/faqs/index.html
 * <p/>
 * Plugging in a Transformer and XML parser http://xml.apache.org/xalan-j/usagepatterns.html#plug
 * <p/>
 * http://marc2.theaimsgroup.com/?l=xml-apache-general&m=101344910514822&w=2 Q. How do I use a different JAXP
 * compatible implementation?
 * <p/>
 * The JAXP 1.1 API allows applications to plug in different JAXP compatible implementations of parsers or XSLT
 * processors. For example, when an application wants to create a new JAXP DocumentBuilderFactory instance, it calls
 * the staic method DocumentBuilderFactory.newInstance(). This causes a search for the name of a concrete subclass of
 * DocumentBuilderFactory using the following order: - The value of a system property like
 * javax.xml.parsers.DocumentBuilderFactory if it exists and is accessible. - The contents of the file
 * $JAVA_HOME/jre/lib/jaxp.properties if it exists. - The Jar Service Provider mechanism specified in the Jar File
 * Specification. A jar file can have a resource (i.e. an embedded file) such as
 * META-INF/javax/xml/parsers/DocumentBuilderFactory containing the name of the concrete class to instantiate. - The
 * fallback platform default implementation.
 * <p/>
 * Of the above ways to specify an implementation, perhaps the most useful is the jar service provider mechanism. To
 * use this mechanism, place the implementation jar file on your classpath. For example, to use Xerces 1.4.4 instead
 * of the version of Crimson which is bundled with JDK 1.4 (Java Development Kit version 1.4), place xerces.jar in
 * your classpath. This mechanism also works with older versions of the JDK which do not bundle JAXP. If you are using
 * JDK 1.4 and above, see the following question for potential problems. see http://java.sun.com/j2se/1
 * .3/docs/guide/jar/jar.html#Service%20Provider
