I use a third party software.
The vendor says that they use log4j to log messages.
I configure my log4j.properties and I can see info from my app but never from theirs.
For example,I change the root category to INFO or to ERROR or to DEBUG.
The question is how do I debug this ?
I have got complete control of the source code but not their jar ?
Any suggestion…
Particularly is there a runtime call I can make to the JVM to tell me why it’s not logging their packages ?
Add this line to your command line :
-Dlog4j.debug=true.
It will show in the system out, how the log4j is initialized.
