When using the Java Web Mapping Application template (created using Manager or Eclipse) the logging level of the application is specified in the web.xml file located under the WEB-INF directory.
<context-param> <param-name>com.esri.adf.LOG_LEVEL</param-name> <param-value>SEVERE</param-value> </context-param>
You can specify a different logging level by modifying the default value of “SEVERE” with any of the following values : ALL, FINE, FINER, CONFIG, SEVERE or OFF
Here is a brief explanation of each level :
FINE, FINER – Fine grained informational events that are useful to debug an application.
CONFIG – Informational messages that highlight the progress of the application at coarse-grained level.
SEVERE– Shows events that might still allow the application to continue running but is important to fix
FATAL – Very severe error events that will presumably lead the application to abort.
ALL – lowest rank and is intended to turn on all logging.
OFF – highest rank and is intended to turn off logging.
