LoggerContext.close() is almost identical to<br>
LoggerContext.reset(). Here is the code:<br>
<br>
class LoggerContext ... {<br>
<br>
public void stop() {<br>
reset();<br>
fireOnStop();<br>
resetAllListeners();<br>
started = false;<br>
}<br>
}<br>
<br>
I don't think calling reset or close should make a difference. You want to release and close appenders which reset() does. Could you post your configuration file?<div class="im"><br>

Hi Ceki,<br>
<br>
well, half-true in my case... I have that code in my<br>
contextDestroyed(..) method, however, for whatever reason I have<br>
lc.reset() instead of lc.stop there... Will change and test that once<br>
I'm back to my dev machine. I will let you know then.<br>
<br>
Thank you for your help.<br>

Hi Rox,<br>
<br>
Are you stopping logback when your application is stopped (and then<br>
started)? The conextDestroyed method of<br></div>
javax.servlet.__<u></u>ServletContextListener is a good place for invoking<br>
such code:<br>
<br>
import javax.servlet.__<u></u>ServletContextListener;<br>
import javax.servlet.__<u></u>ServletContextEvent;<br>
import org.slf4j.LoggerFactory;<br>
import ch.qos.logback.classic.__<u></u>LoggerContext;<div class="im"><br>
<br>
public class MyServletContextListener implements<br>
ServletContextListener {<br>
<br></div>
public void contextInitialized(__<u></u>ServletContextEvent sce) {<br>
}<br>
<br>
public void contextDestroyed(__<u></u>ServletContextEvent sce) {<br>
LoggerContext lc =<br>
(LoggerContext) LoggerFactory.__<u></u>getILoggerFactory();<div class="im"><br>
lc.stop();<br>
}<br>
<br>
Please let us know if stopping logback as described above helps.<br>

Hi all,<br>
<br>
I have a trouble with logback configuration under WebLogic 12c. My<br>
application is using RollingFile Appender with<br>
TimeBasedRollingPolicy<br>
and the problem is it stops logging every time I stop and then<br>
start the<br>
application through WebLogic Console. However, the logging is<br>
back when<br>
a rollover occurs - in the new file logging continues...<br>
<br>
Has anyone faced such behavior (and knows the solution)?<br>
<br>
Thank you in advance.<br>
<br>
Regards,<br>
