Without this parameter, Log4j will use the standard mechanisms for locating the configuration file. When specifying these context parameters, you must specify them in the deployment descriptor web. If you add them to the ServletContext within a listener, Log4j will initialize before the context parameters are available and they will have no effect.

Here are some sample uses of these context parameters. Note that in this case you must also set the "Log4jContextSelector" system property to " org.

This does not affect Tomcat 6. The handling of asynchronous requests is tricky, and regardless of Servlet container version or configuration Log4j cannot handle everything automatically. When standard requests, forwards, includes, and error resources are processed, the Log4jServletFilter binds the LoggerContext to the thread handling the request.

After request processing completes, the filter unbinds the LoggerContext from the thread. Similarly, when an internal request is dispatched using a javax. AsyncContext, the Log4jServletFilter also binds the LoggerContext to the thread handling the request and unbinds it when request processing completes.

However, this only happens for requests dispatched through the AsyncContext. There are other asynchronous activities that can take place other than internal dispatched requests.

For example, after starting an AsyncContext you could start up a separate thread to process the request in the background, possibly writing the response with the ServletOutputStream. Filters cannot intercept the execution of this thread. Filters also cannot intercept threads that you start in the background during non-asynchronous requests. Active Oldest Votes.
