is to retrieve an object reference to the LogFactory instance that will be used to create Log instances for this application. This is normally accomplished by calling the static getFactory() method. This method implements the following discovery algorithm to select the name of the LogFactory implementation class this application wants to use: Check for a system property named org.apache.commons.logging.LogFactory. Use the JDK 1.3 JAR Services Discovery mechanism (see http://java.sun.com/j2se/1.3/...
