WebSphere Application Server handlers are attached to the Java
root logger in the logger hierarchy. As a result, any request from anywhere
in the logger tree can be processed by WebSphere Application Server handlers.
WebSphere Application You can configure the system to do the following tasks:
- Forward all application logging requests to the WebSphere Application
Server handlers. This is the default behavior.
- Forward all application logging requests to your own custom handlers.
To do this, set useParentHandlers to false on
one of your custom loggers, and then attach your handlers to that logger.
- Forward all application logging requests to both WebSphere Application
Server handlers, and your custom handlers, but do not forward WebSphere Application
Server logging requests to your custom handlers. To do this, set useParentHandlers to true on
one of your non-root custom loggers (true is the default
setting) , and then attach your handlers to that logger.
- Forward all WebSphere Application Server logging requests to both WebSphere
Application Server handlers, and your custom handlers. WebSphere Application
Server logging requests are always forwarded to WebSphere Application Server
handlers. To forward WebSphere Application Server requests to your custom
handlers, attach your custom handlers to the Java root logger, so that they
are at the same level in the hierarchy as the WebSphere Application Server
handlers.
The example below shows how these requirements can be met using the Java
logging infrastructure.
