Re: Can't figure out how to change email appender subject dynamically
Maarten, That was it! Calling appender.activateOptions(); did the trick. Thanks SO much! David.

logging into different files
Have an application where the number of threads that get launched are dynamic. Could be anywhere from 1 to 300 threads that could get launched at runtime. I would like to know if it is possible to setup a file appender for each thread and have the indiv threads write to their own file appender. Currently all threads write to one log file using 1 file appender in a log4j.properties file but would like ability for each thread to log its own messages for easier debugging. Any good sites or source would be great. Any help would be appreciated. -- View this message in context: http://www.nabble.com/logging-into-different-files-tf2422885.html#a6754850 Sent from the Log4j - Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
logging into different files
This was discussed a lot on this list. Search in archive, keywords: MDC, RepositorySelector, different files. We currently discuss on the developper list the introduction of a MultiFileAppender which addresses just your need. But the work is still in progress...

Re: Can I change log4j configuration programatically?
A stand-alone Java application could use
DOMConfigurator.configureAndWatch (but don't allow it to do automatic
configuration).

sql.
Is it possible to to this? If so, how do I go about doing this?
Thanks in advance

Re: logging into different files
That should be possible by writing your own appender. Search the archives as this was discussed recently.

Re: Can I change log4j configuration programatically?
I see...no it's just a standalone Java application. James is probably wondering whether your code is running in a web container, such as Tomcat. In that case, LogWeb might be able to help http://www.codeczar.com/products/logweb/ It works great for me!

Re: logging into different files
I think that you could use something like: PatternLayout pattern = new PatternLayout(your pattern); String filename = some file name based on thread name; FileAppender threadAppender = new FileAppender(pattern, filename); String threadLogName = some log name derived from thread name; Logger threadLog = Logger.getLogger(threadLogName); threadLog.setAdditivity(false); threadLog.addAppender(threadLog); Michael Giroux On 10/11/06, sudhakardvvn [EMAIL PROTECTED] wrote: Have an application where the number of threads that get launched are dynamic.

Re: Can I change log4j configuration programatically?
Well, I use DOMConfigurator initially, but what about when the program is running?? I would like to set a new root level or a log file size. Can I do something like Logger.getRootLogger.setLevel or something like that? If I do it this way do I have to stop and restart the logger?

Re: Can I change log4j configuration programatically?
Using configureAndWatch you can just change the file and it will update based on the changes.
