Enrique,
1. This should be determined by how much detail you want from your logs. We have several different categories setup by functional area from our application, so when we read the logs, we can just look within the functional area we are interested in. If your project is small enough, you may only need 1 logger. Some large apps may use hundreds. 2. I have used the following line within my config.xml file to get the class and line number with no problem. <param name="ConversionPattern" value="CLASS=%C%nLine_No=%L"/> -Manish "Enrique Rodriguez" <[EMAIL PROTECTED]> on 04/03/2002 11:22:16 PM Please respond to "Log4J Users List" <[EMAIL PROTECTED]> To: "Log4J Users List" <[EMAIL PROTECTED]> cc: Subject: Newbie cuestions Hi all, i am testing log4j and I've two dudes(i have more but... ;-)) 1.- How many Categories-logger must i define???
