How can I insert a specific variable in log while using log4j, so as to be able to present more meaningful log output? In case of multi-threads application, it is always desirable to have an entry specific to which thread logs this LOG to log file. It is like sending a specific message/variable value to all log messages. org.apache.log4j.NDC can be used for this purpose. NDC stands for Nested Diagnostic Contexts. Just before starting to use logger code, NDC.push() method with a String parameter value, can be called and just before leaving or completing method scope, NDC.pop() method can be called. It is always advisable to remove NDC before exiting operation by calling NDC.remove method. If you have any other opinion or suggestion to be made on this, please do so, by replying to this write up. After review and required changes made, if any, it will be published in this page.
