[jetty-users] One log file per context

[Libor Jelinek <ljelinek@xxxxxxxxxxx>]

Hello (Joakim)!

I'm unsucessfully trying to have one log file per deployed context. Found SO quesion http://stackoverflow.com/questions/11902550/jetty-log-per-context that directs to Jetty wiki http://wiki.eclipse.org/Jetty/Tutorial/Sifting_Logs_with_Logback.

I followed the tutorial from wiki but I want one log file per context, not per host as described in that page. So I added line

MDC.put("context",request.getContextPath());

to MDCHandler (https://github.com/jetty-project/jetty-and-logback-example/blob/master/jetty-slf4j-mdc-handler/src/main/java/org/eclipse/jetty/examples/logging/MDCHandler.java). It looks now like this:

public class MDCHandler extends HandlerWrapper

{


    @Override
    public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException

    {


        try
        {

            MDC.put("host",request.getServerName());

            MDC.put("context",request.getContextPath());


            super.handle(target,baseRequest,request,response);

        }


        finally
        {

            MDC.clear();

        }


    }
}

But MDC "context" is always null. According to http://docs.oracle.com/javaee/5/api/javax/servlet/http/HttpServletRequest.html#getContextPath() it cannot be null. Even for root contexts (/) method should return empty string (""). Therefore I can't use it for Logback sifting.

Is there anybody who achived "one log file per context" solution? Can you share your know-how?

Thanks!
