Hello Logback-User support,
I am using common logback.xml file, which is loaded programmatically from
different J2EE web applications and which writes to different log files using
"SiftingAppender".
Everything works fine unless logback.xml file has been modified. Once it has
been modified, it gets scanned & reloaded as per configuration of scanPeriod,
post which it does not recognize the context properties and it still writes all
the logs, but in a separate file (with suffix of application-name_IS_UNDEFINED)
for al lthe applications.
Logback version : 1.0.13
Logback configuration
<appender name="LogFile" class="ch.qos.logback.classic.sift.SiftingAppender">
<discriminator>
<key>application-name</key>
<defaultValue>5</defaultValue>
</discriminator>
<sift>
<appender name="${application-name}"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<prudent>false</prudent>
<file>C:/logs/${application-name}.log</file>
<rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover -->
<fileNamePattern>c:/logs/${application-name}.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">

Logback Loading programmatically from the Context Listener class
LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory();
JoranConfigurator jc = new JoranConfigurator();
jc.setContext(context);
context.reset();
context.putProperty("application-name",
sce.getServletContext().getServletContextName());
String logFilePath = sce.getServletContext().getInitParameter(INIT_PARAM_NAME);
if (logFilePath==null){
throw new RuntimeException("Unable to load init parameter " + INIT_PARAM_NAME +
" from web.xml file");
}
try{
jc.doConfigure(logFilePath);
} catch (Exception e){
e.printStackTrace();
throw new RuntimeException("Unable to load logback.xml file successfully @
" + logFilePath, e);
}
Is this a known issue? Is there a fix for this already? Please advise.
Appreciate!
