Thanks Eric, thats exactly what I was looking for.
A noob question, so if a user hits the webpage, servlet is going to create
a thread for the same. Now if I do logger after setting up MDC id like this:
logger.info (" Great")
So technically how this can be converted or remembered per thread?
Because imagine I did set the id as 121, and two users are hitting, which
is going to be altogether different threads, how does this 121 gets binded
to threads in this case?
>From my understanding so if a user going to access the webpage, then he or
she needs to "somehow" pass on this id to MDC, then I believe it works as
required.
Correct me if I'm wrong.
Anto.
