Janusz,
The answer is in the log4j/helpers/PatternParser.java code (used by
PatternLayout.java). %x is for NDC. %X is for MDC. You will probably want
to specify the particular MDC key, and that would be like this:
%X{<key name>}
Try it and see if it works for you.

[Ceki, I think the PatternLayout javadoc needs to be updated to include this
new conversion pattern.]

Subject: MDC layout parameter
Hi,
I would like MDC to print my sub-system name (my sub-system is separate
app running under jvm). I am using log4j 1.2 beata.
I am trying to use MDC because if I understand properly all children
threads of the main thread will use the same context value, and that is
exactly what I want.
I can't get that to work - I am using in my PatternLayout %x flag to do
that - is that the reason it does not work. I was trying to look inside
a code, but can't find anything.
