AW: does log4j support wildcard
But is that given solution a real wildcard? "${user.dir}/../logs/eco" I guess no.
1.${user.dir} muts be define dpreviously or it comes implementation dependent as ""
2. and this may lead to errors
3. then /../ directs to go up in the tree one level
4. before you go down in the tree to /logs/eco
Given ${user.dir} is not defined when used, what is the outcome?
${user.dir} must be a property may be a macro which is defined prior to beeing used.
But if you say C:\ > dir stade*.doc then the "*" is a true wildcard saying
that anything wild after "stade" can stay unless the dot is received from
where on only files with a doc extension will be listed in the directory
command.
So
stade1.doc
stade2.doc
stadeX.doc
but not
stadeN.dot
are listed
Also id ${user.dior} would be something like 112345 (as possible for wildcards)
Would that make sense in the wanted use and context? No, so I would not refer to
${user.dir} as to a widlcard, even ${user.dir} migth be defined to a valid user
On most OS and platforms, but have to lead/form part of a TRUE PATH in the end.
While this is not necessary for a true wildcard character.
Or do we have to re-define what wildcards are?

Posted by Stadelmann Josef <jo...@axa-winterthur.ch>.
Now I agree with you 100%; Guess it makes sense sometimes to read from
various paths using wildcard's in the paths. But writing to paths (plural)
does not make a lot sense. :-)
Placeholder makes however big sense.

Re: does log4j support wildcard
Posted by JOSE L MARTINEZ-AVIAL <jl...@gmail.com>.
user.dir is a system properties, as defined in
http://download.oracle.com/javase/1.4.2/docs/api/java/lang/System.html
You can setup dinamically other variable and use it. But you are right in
the sense that it is not a wildcard. What I'm wondering is in what context
makes sense to use a wildcard when defining the path where a file will be
written. What happens if there is more than one path that can fit the
wildcard? which one is used?
