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.
