RE: [SPAM (Bayesain Analysis)] - Can i instentiate the log4j logger object? - Bayesian Filter detected spam
Hallo Michael About a year ago it was discussed to have a MultiFileAppender which can cover exactly this problem. The idea did not get over a sandbox project and is now sleeping. Using current version of log4j it is possible if you write your own repository selector. The default repository is also a singleton, but your self written selector can instantiate a repository for each thread. On each thread start you will then configure your appender(s) by code. Look at the archive, this was discussed a lot (a year or two ago).

Because the Logger object is singleton. Is there any way that I can have init 2 different instance of Logger (with different configuration of file to be write to) on each thread and each their own log files ??

Thanks, Logger is not singleton, there can be many instances of Logger. However, only one logger in a hierarchy can gave a particular name. Having multiple hierarchies (which would allow you to have multiple instances of Logger with the same name) would require that you pass the Logger or LoggerRepository as a parameter to all your methods or use some other mechanism to access the appropriate repository for your thread. A better approach is to have a single appender that writes to multiple files depending on the thread making the logging request. There was a discussion on 16-Oct-2007 on log4j-user of an appender that used thread local storage to accomplish that. Also, there was a experimental effort to develop a MultifileAppender where file-per- thread was one of several use-cases, but that effort languished because of competing demands on my time and no others pitching in. As mentioned in the recent thread on log4j-user, the topic has come up repeatedly recently and I'd like to finish off the MultifileAppender effort and put it into extras. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
