NAME
       Log::Log4perl::JavaMap - maps java log4j appenders to Log::Dispatch classes

SYNOPSIS
	    ###############################
	    log4j.appender.FileAppndr1	      = org.apache.log4j.FileAppender
	    log4j.appender.FileAppndr1.File   = /var/log/onetime.log
	    log4j.appender.FileAppndr1.Append = false

	    log4j.appender.FileAppndr1.layout = org.apache.log4j.PatternLayout
	    log4j.appender.FileAppndr1.layout.ConversionPattern=%d %4r [%t] %-5p %c %x - %m%n
	    ###############################

DESCRIPTION
       If somebody wants to create an appender called "org.apache.log4j.ConsoleAppender", we want to translate it to Log::Dispatch::Screen, and
       then translate the log4j options into Log::Dispatch parameters..

   What's Implemented
       (Note that you can always use the Log::Dispatch::* module.  By 'implemented' I mean having a translation class that translates log4j
       options into the Log::Dispatch options so you can use log4j rather than log4perl syntax in your config file.)

       Here's the list of appenders I see on the current (6/2002) log4j site.

       These are implemented

	   ConsoleAppender     - Log::Dispatch::Screen
	   FileAppender        - Log::Dispatch::File
	   RollingFileAppender - Log::Dispatch::FileRotate (by Mark Pfeiffer)
	   JDBCAppender        - Log::Log4perl::Appender::DBI
	   SyslogAppender      - Log::Dispatch::Syslog
	   NTEventLogAppender  - Log::Dispatch::Win32EventLog

       These should/will/might be implemented

	   DailyRollingFileAppender -
	   SMTPAppender     - Log::Dispatch::Email::MailSender

       These might be implemented but they don't have corresponding classes in Log::Dispatch (yet):

	   NullAppender
	   TelnetAppender

       These might be simulated

	   LF5Appender - use Tk?
	   ExternallyRolledFileAppender - catch a HUP instead?

       These will probably not be implemented

	   AsyncAppender
	   JMSAppender
	   SocketAppender - (ships a serialized LoggingEvent to the server side)
	   SocketHubAppender

ROLL YOUR OWN
       Let's say you've in a mixed Java/Perl enviroment and you've come up with some custom Java appender with behavior you want to use in both
       worlds, "myorg.customAppender".	You write a Perl appender with the same behavior "Myorg::CustomAppender". You want to use one config file
       accross both applications, so the config file will have to say 'myorg.customAppender'.  But the mapping from "myorg.customAppender" to
       "Myorg::CustomAppender" isn't in this JavaMap class, so what do you do?

       In  your Perl code, before you call Log::Log4perl::init(), do this:

	   $Log::Log4perl::JavaMap::user_defined{'myorg.customAppender'} =
	       'Myorg::CustomAppender';

       and you can use 'myorg.customAppender' in your config file with impunity.
