Hi Arash, configuring =92System.property=92, =91classpath=92 are the basic =
nuts and bolts of Java. If you have done any amount of programming =A0in Ja=
va though basic. this should be self explanatory.=0A=
=0A=
try revisiting the basics and start executing java programs *without* an ID=
E =97 this will be a good exercise.=0A=
=0A=
Now, having said that: log4j2 will =93automatically=94 detect your configur=
ation available in the supported formats (points 1-9 in the section =93Auto=
matic Configuration=94). Optionally, =A0if your config is in another place =
or you would like to pick it up from a different location other than your p=
roject =97 only then you need to set the property=A0log4j.configurationFile=
=A0.=0A=
=0A=
I hope this makes it clear.=0A=
=0A=

Laurent, although my Java use-case was very simple (1 file, < 100 lines). I=
=0A=
still needed to log to stdout+file at the same time. Hence I needed a=0A=
logging framework (please correct me if I'm wrong). As Matt said, logging=
=0A=
is a "fundamental" library.=0A=
=0A=
At the same time I do agree with Luarent. The internet already define=0A=
classpath at a gazillion places[1][2]. Let's not just restate what is=0A=
there. I suggest something very practical and only geared to log4j2.  What=
=0A=
about creating a repo like [3] and linking to it from the docs? Just make=
=0A=
it officially under the log4j2 organization and commit to keep it up to=0A=
date. What do the community think?=0A=
