Customizing log4j1 configuration

The application uses the log4j1 utility for logging. The log4j1 utility writes trace and debug information to a log file. You can modify the logging parameters in the log4j1 configuration file to control the location and level of the log files. You can configure the logger to send different categories of messages to different destinations. Categories are organized hierarchically, which permits inheritance. Each category can be configured with a priority to indicate a severity level. If a category is not configured with a priority, it inherits the priority of its closest ancestor with an assigned priority.
