RE: Request for working log4j configuration file (properties or XML) in Tomcat 4.0.4

[Venkateshwar Bommineni <vb...@elogex.com>]

How that file gets read? through a Servlet. I had the similar problem. 

For short fix, I am initilazing through Properties file which loads
log4j.properites file using hard coded path. code snippet:

       try {
            InputStream inStream =
getServletContext().getResourceAsStream("/WEB-INF/classes/log4j.properti
es");

            Properties configProps = new Properties();
            configProps.load(inStream);
            PropertyConfigurator.configure(configProps);

            log = Logger.getLogger("com.foo");

        } catch (Exception ep) {
            throw new ServletException("Unable to initialize Logging
Service");
        }


Any one can provide solution or suggest some other better way to do
that.

thanks in advance
Venkat

If anyone has a working log4j configuration file that they are using in
Tomcat 4.0.4, please forward.

 

I always get the no appenders warnings.

log4j:WARN No appenders could be found for logger (DoraLogger).

log4j:WARN Please initialize the log4j system properly.

 

The following configuration file in my webapp's web-inf/classes
directory
never gets read.
