Hi Arul, Video on Log4J was really good. I need a clarification as I was tying to implement the concept in my project. Project is a MAVEN project and i have added the dependencies "org.apache.logging.log4j" with version 2.14.0 . File getting imported is "import org.apache.logging.log4j.Logger". and when I am getting an error on this statement ---> static Logger logger = Logger.getLogger(Propertylog4jExample.Class); I am getting a compile time error on Propertylog4jExample.Class. Could you please help me on this.

Is it required to learn the formats of XML file and Properties file or copy pasting from Google would suffice ? I understood the explanation but those formats are a bit difficult to grasp.

Make sure the patter you have given in the property file is correct. May be the pattern changed now. Search in Google and try out different patterns to see if something is changing .
