Development/Java & J2EE/Logging For logging, should nodays be using the Commons logger (instead of directly referencing log4j). ie: {code} public class MyClass { private static final Log LOG = LogFactory.getLog(MyClass.class); } {code} Levels: {code} static Level DEBUG - The DEBUG Level designates fine-grained informational events that are most useful to debug an application. static Level INFO - The INFO level designates informational messages that highlight the progress of the application at coarse-grained level. static Level WARN - The WARN level designates potentially harmful situations. static Level ERROR - The ERROR level designates error events that might still allow the application to continue running. static Level FATAL - The FATAL level designates very severe error events that will presumably lead the application to abort. {code} Ref: http://www.allapplabs.com/log4j/log4j_appenders.htm ---- 1 Additinal logging toolsets: AuditLog: http://www.acelet.org/_auditlog/AuditLog.html 2008-04-23 12:45:24.0 2006-01-03 12:28:25.0
