Logging activity in JBoss environments

All NexJ applications running on JBoss application servers use Apache log4j, a Java-based logging utility, to generate log files.

Log4j outputs two types of log files:

NexJ Model Engine: NexJ Model Engine log files contain all messages associated with your NexJ application business logic.
They have the following naming convention: nexj-environment.log.
Application server: Application server log files contain messages generated by the JBoss application server. These are not messages from NexJ Model Engine.
They have the following naming convention: server-environment.log.

Log4j uses an XML configuration file called jboss-log4j.xml. It is located in the JBOSS_HOME\server\project\conf\ directory. You can modify this XML file to customize logging functionality for your specific business needs, such as logging information for individual users or specific components of the model.

Note: For more information about this functionality, see the Apache log4j website.
