My logging system(on log4j-1.13) has some extensions based on the idea of application server category extension in log4j-1.13 to insert informations outside log4j to logs. In log4j-1.2x, however, extending Category/Logger is not recommended and it seems extensions should go to LoggingEvent/PatternLayout/PatternParser.
One problem rises here: If one extend LoggingEvent without extending Category/Logger, there is no way to use this extended LoggingEvent class in the system, because the only entry to log4j with LoggingEvent exposed is Category#forcedLog(). I haven't found a way to specify a extended LoggingEvent class in the configuration files, neither xml or properties. Of course I can hack PatternParser to insert those external information but I think it logically incorrect(some information should be part of a logging event) and not scalable too. I find LoggingEvent(in log4j-1.28) still uses Category and Priority in it's constructor instead of Logger and Level, which force my extension to use those two deprecated class also. Does the above understanding is correct? I used log4j from it's 0.9x versions and still hope to use it as the backbone of my logging implementation in the future. Any ideas and suggestions about log4j extensions are welcome.
