log4j in jsp

[Shin Hashitani]

Hi everybody,
Windows 2000 JRun4 log4J1.2.6 JDK1.4.1

I am having trouble identifying Logger in jsp:
<%@ page import="org.apache.log4j.Logger" %>
...
Logger log4 = null;

log4 = Logger.getLogger(this.getClass());
log4.debug("testing log4j");
I tried the above code, and nothing comes out. In case of JSP, I believe the name of the class that would be generated depends on a kind of application server. In that case, getLogger(MyClass.class); is not a good way to define Logger.
But how do I find the name of the class at runtime? It seems that everyone is having no problem using Log4J except me.
Thank you

In the case of a JSP I don't create a logger using the class name at all. I bascially obtain the path to the JSP file from the request, replace the /s with ".", remove the .jsp extension and prefix the logger name with "jsp.". Makes for a nicer logger name that distinguishes JSP loggers from Java class loggers.
So an example logger name (for a page at web/pages/somefolder/mypage.jsp) might be:

jsp.web.pages.somefolder.mypage

Additionally, I created a set of custom tags to do JSP logging so that I don't have to code Java scriplets in the pages just to use logging.
