Understanding WebLogic's logging service

Before we advance to the event system introduced in Java EE 6, let's take a look at the logging services provided by Oracle WebLogic Server.

By default, WebLogic Server creates two log files for each managed server:

• access.log: This is a standard HTTP access log, where requests to web resources of a specific server instance are registered with details such as HTTP return code, the resource path, response time, among others

• <ServerName.log>: This contains the log messages generated by the WebLogic services and deployed applications of that specific server instance

These files are generated in a default directory structure that follows the pattern $DOMAIN_NAME/servers/<SERVER_NAME>/logs/.

If you are running a WebLogic domain that spawns over more than one machine, you will find another log file named <DomainName>.log in the machine where the administration server is running. This file aggregates messages from all managed servers of that...
