-------------------------------------
Summary: Log4j2 JMX: getConfigText in LoggerContext is not working
as documented
Key: LOG4J2-638
URL: https://issues.apache.org/jira/browse/LOG4J2-638
Project: Log4j 2
Issue Type: Bug
Reporter: Mansoor Sajjad
I am trying to configure log4j2 to access the loggers via JMX and change their
log levels.
There are two operations that are available via LoggerContext in JConsole.
getConfigText
setConfigText
The problem is with the first one. According to the documentation:
getConfigText returns the configuration text, which may be
The contents of the configuration file.
The text that was last set with a call to setConfigText.
The problem is that getConfigText works fine with second statement but its not
working with the first one. Which means if you try to get the configuration
text without first setting it with the setConfigText, you will see the
exception instead. The follow one:
java.io.FileNotFoundException: /usr/local/Cellar/tomcat/7.0.47/libexec/bin/Erex

I have set the configuration file path as a part of VM parameters like that:
-Dlog4j.configurationFile=file:/Users/mansoor.sajjad/ErexLogs/exchange/conf/log4j2.xml
But the exception logs showing that its trying to get the path from within
tomcat /usr/local/Cellar/tomcat/7.0.47/libexec/bin/Erex
Why is it so?
