Placing a webapp log file aside by other server log files

["USHAKOV, Sergey" <s....@chemitech.ru>]

Hi all,

I am looking for a robust way to get a webapp-specific log file be placed in 
the same directory where all the other server logs go.

Using a line like "org.apache.juli.FileHandler.directory = 
${catalina.base}/logs" in the webapp's "logging.properties" does not do the 
job, as server logs location may be changed from ${catalina.base}/logs to 
something else by the server's "logging.properties".

Any ideas?

Thanks and best regards,
Sergey

Thank you Mark. Though that does not look like a solution I might be willing 
to get :) , this will definitety do the job if no other solution is found...

Thanks again,
Sergey

This is probably not the best way, since it will require you to configure information in two places (and keep it in sync). However, it should work.

In $CATALINA_BASE/bin/setenv.sh add something like the following to your JAVA_OPTS:

JAVA_OPTS="-Dwebapp.logs=some-directory"
EXPORT JAVA_OPTS

In your web application's logging.properties reference ${webapp.logs}/some-file.

This seems to work reasonably well for me using log4j and commons-logging.

. . . . just my two cents.
