java - Best way to interact with application logs output from log4j (while also are being updated by application) -

may simpler think confused on following:

i want able nowadays user (in graphical interface) logs produced log4j.

i read files , nowadays it, wondering if there standard way updates happen @ same time other parts of application log concurrently.

the log4j files multiple i.e. rolling appender

also presentation while there no logging happening. i.e. view of logs date

update: constraint java 6

you can utilize java 7's nio2 libraries notified when 1 of multiple files get's modified in directory, , reread & display it:
