Hi, I am trying to add few conversion characters to pattern layout. Values of some of them are known at the logger initialization and for few it can be passed per-message. I was looking at following guideline -
http://www.ingrid.org/jajakarta/log4j/jakarta-log4j-1.1.3/docs/deepExten sion.html This seems to fit my needs perfectly. Then I realized that we should use Logger instead of Category class. Java doc also says that Category is deprecated. Fine, Now when I try to subclass Logger, it is not possible as well as not advisable for various reasons. See the conversation thread below. So, now I have a road block. I can not use Category class. I can not sublcass Logger. If I wrap Logger class, I can not override forcedLog method of Logger/Category so as to provide my custom LoggingEvent class. Please help me to figure out how to do this. I think the guideline in above URL is not possible with log4j-1.2.8. What I am wondering is whether it is possible to add conversion charactors to PatternLayout?

Logger vs category tag in xml (DOMConfigurator) This subject has been discussed many times in the past. Please refer to the archives. No, it is not a bug. Subclassing logger class is discouraged. Consequently, the logger tag does not allow for a class attribute. However, you can get around this by various means which I am not going to disclose here as the means are deprecated, discouraged or both. I recommend wrapping instead of sub-classing.
