The protocol stack configurator is an object that read a stack configuration and parses it so that the ProtocolStack can create a stack. Currently the factory returns one of the following objects: 1. XmlConfigurator - parses XML files 2. PlainConfigurator - uses the old style strings UDP:FRAG: etc etc author:    Filip Hanik (filip@filip.net) author:    Bela Ban version:    $Id: ConfiguratorFactory.java,v 1.22 2006/10/09 13:34:00 belaban Exp $ Field Summary final static  String FORCE_CONFIGURATION      final public static  String JAXP_MISSING_ERROR_MSG      final static  Log log      static  String propertiesOverride      Constructor Summary protected   ConfiguratorFactory()      Method Summary static  void checkForNullConfiguration(Object properties)      Check to see if the specified configuration properties are null which is not allowed. static  void checkJAXPAvailability()      Checks the availability of the JAXP classes on the classpath. static  ChannelException createChannelConfigurationException(Throwable cause)      Creates a ChannelException instance based upon a configuration problem. public static  InputStream getConfigStream(File file)      public static  InputStream getConfigStream(URL url)      public static  InputStream getConfigStream(String properties)      Returns a JGroups XML configuration InputStream based on the provided properties string. public static  InputStream getConfigStream(Object properties)      public static  ProtocolStackConfigurator getStackConfigurator(File file)      Returns a protocol stack configurator based on the XML configuration provided by the specified File.
