configuring appenders

[Julie F McCabe <mc...@jpmorgan.com>]

Hi all,

I have managed to get very confused with log4j & seem to be missing the
efficiency it has to offer.  My problem is I have created my own category, the
aim is to write to 4 different files with the respective cat1 - cat4 categorties
and the console category for writting to system.out for debugging purposes only.
Therefore in the config file below, if I comment out log4j.category.console.cat
= INFO then I should have no logging to system.out, right?  However, the
particular implementation does not work as expected.  Any suggestions?
Basically I want to have a category that I can switch off from the config file
once the program goes into production.

Thanks,
Julie Mc Cabe


config file:

log4j.categoryFactory=com.jpmorgan.researchcontent.transmit.TransmitCategoryFactory
log4j.rootCategory=debug

log4j.category.console.cat = INFO
log4j.category.com.jpmorgan.researchcontent.transmit.cat1.cat=WARN
log4j.category.com.jpmorgan.researchcontent.transmit.cat2.cat=WARN
log4j.category.com.jpmorgan.researchcontent.transmit.cat3.cat=WARN
log4j.category.com.jpmorgan.researchcontent.transmit.cat4.cat=WARN



source code:

to create the default logging parameters
static public void createCategory(String className) {

      PropertyConfigurator.configure(configFile);

      Category root = Category.getRoot();

      console = (TransmitCategory)TransmitCategory.getInstance("console");
      console.addAppender(new FileAppender(new PatternLayout("%-5d %-5x Msg:
%m%n"), System.out));
      console.setPriority(org.apache.log4j.Priority.INFO);
      console.setAdditivity(false);*/


      cat = (TransmitCategory)TransmitCategory.getInstance(className);
      try {
           cat.addAppender(new FileAppender(layout, default, false));
          cat.setPriority(org.apache.log4j.Priority.WARN);
      } catch(IOException e) {e.printStackTrace();}

  }



 to add different categories
 static public void appendToRoot(String system, String className, String
filename) {
      String filename = "";

    try {

        cat = (TransmitCategory)TransmitCategory.getInstance(className);
        file = new FileAppender(layout, filename, true);
        cat.addAppender(file);
        cat.setPriority(org.apache.log4j.Priority.WARN);
        } catch(ClassCastException e) {
      e.printStackTrace();
    }
    catch(IOException e) {
      e.printStackTrace();
    }
