log4j issue

["Satrasala, Sudhakar" <Su...@adp.com>]

Hi,
 
I get an error message when trying to log. I don't have a console appender
entry in my configuration file. Still,. My configurator code looks like:
 
URL url = LoggingConfigurator.class.getResource("/log.xml");
DOMConfigurator.configure(url.getFile());
 
I keep getting this error everytime.
        
log4j:ERROR Attempted to append to closed appender named [console]

Setting multiple log threshold in multi-threaded environment

[Shachindra Agarwal <sh...@metallect.com>]

Hello:

I am a new user of log4j. I am trying to use it in a multi-user,
multi-threaded environment. In this environment, each thread performs
operations on behalf of a unique user. Each user may have different log
threshold levels. For example, we may want to log only FATAL messages = for
user 'joe', whereas we may wish to log ALL messages for user 'pete'.

As per the recommendations, I have created a static logger instance across
all the threads. However, I can now only set a single log threshold level
across all the threads. I realize I can simulate multiple log threshold
levels (one per thread - for each user) by using MDC, but that is expensive.

Am I missing anything? Should I be creating one logger object per thread?

Thanks for your input.
