Hi Arul, very nice explanation, What does mean slf4j ?

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.

Hi my small doubt is while using Property file we mentioned RollingFile Appender but in xml, we used File Appender but final outcome was same for both scenarios. Are both same?

This version log4j is no longer available. please visit some other tutorial.

Sir in this video for Basic configurator.. %x denotes?

Neenga yepdi debug pannuvinga In eclipse if facing issue in script Do u use log file instead of debugging

hi bro kindly increase the video quality..

hi arul i got FileNotFoundException

Arul, is it possible to provide the log4j XML tags in the same XML sheet where we run our test cases from and for the Properties configurator also, where we have the config.properties file?

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.

Hi Sir! i am happy to say that i have learned many concepts with your support and can you please come up with new video of Logger4java, because there no option in buildpath to refer jar folder in classpath level and more log4j jar while extract from web and cant import the above statement in my eclipse

now logger is available in java also.. is both the same or different.

I executed the Properties file concept, no exception is coming the log is successfully created, but the details are missing the pattern is missing, only the messages are displaying. Can you say why?

Hi Bro , When i execute the program , i am getting the below error . ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. I am not sure why it is looking for log4j2 configuration file - the filename which i dont have
