While Logback supports using prudent mode for this, I don't recommend it.

With that you should have no problem having multiple web apps write to the same file.</div><div><br></div><br><div><div>On Oct 31, 2012, at 5:56 AM, Gaurav Kumar wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr">any suggestions will be really appreciated.

I have a scenario with multiple Web Applications (so multiple wars into jetty/webapps dir). Each war has its own copy of logback-classic, logback-core and slf4j-api. There is a common copy of logback.xml in jetty/resources (pasted below). My intent is to maintain a logfile named "testapp.<date>.log" which should be used by all the wars for logging. Further, I want a rollover of this file on every startup. I am able to achieve this except that each war is trying to create its own version of the log file so when each war is loaded it creates its own logfile archiving the earlier logfile created by the earlier war. This continues till all wars are loaded thus creating these many log files per startup. The archived files are are named "testapp.<date>.log.<time in millisec>.<br>
