WebSphere Application Server handlers are attached to the Java root logger, which is at the top of the logger hierarchy. As a result, any request from anywhere in the logger tree can be processed by WebSphere Application Server handlers.
With WebSphere Application Server, you can configure the system to do the following:
Forward all application logging requests to the WebSphere Application Server handlers. This behavior is the default.
Forward all application logging requests to your own custom handlers.
Set the
useParentHandlers option 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. Set the
useParentHandlers option to true on one of your non-root custom loggers, and then attach your handlers to that logger.True is the default setting.
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 following example shows how these requirements can be met using the Java logging infrastructure.
