Re: [xmlblaster-devel] Redirect LogChannel for log4j

[Uwe Renzland <uwe at renzland.de>]

Hi Marcel, 

I saw, that the changes are not so easy, because not all possible
LogChannels 
are known within the Global Object in the moment, I want 
to initialize my logging. They are inserted dynamically when 
they are used. 

So I did not make any changes within the famous xmlBlaster and
initializes 
my logging in the following way (this is not a good solution, but it
considers 
all known log ids, more I do not need): 

  /**
   * add 'this' to all known LogChannels 
   * so this.log() will be triggerd for all xmlBlaster specific logs. 
   * So we have a chance, to log xmlBlaster stuff into our logfile.
   */
  private void initXmlBlasterLogging() 
  {
    if (xmlBlasterLoggingInitialized) 
      return; 
    xmlBlasterLoggingInitialized = true; 
    glob.getLog("core").addLogDevice(this);
    glob.getLog("auth").addLogDevice(this);
    glob.getLog("cb").addLogDevice(this);
    glob.getLog("mime").addLogDevice(this);
    glob.getLog("corba").addLogDevice(this);
    glob.getLog("xmlrpc").addLogDevice(this);
    glob.getLog("admin").addLogDevice(this);
  }
