I have followed the wiki regarding Repository Selectors for initialising log4j, and have got it working for my web apps.
I am using struts 1.2 and in the struts actions, I can use log4j and have it log properly. I also have a log statement inside the InitServlet where log4j is initialised and it works too.
However when I try and log from inside a servlet filter the logging does not get executed at all.
The filter is one to determine if a user is logged in, and if not redirect to the login page. This is working as the redirection happens properly. However the logging is not.
This works:
public class InitServlet
extends HttpServlet {
private static Logger log;
public void init(ServletConfig config)
throws ServletException {
super.init(config);
ServletContext context = config.getServletContext();
System.setProperty("log4j.log.dir", getInitParameter("log4j.log_directory"));
String configFile = getInitParameter("log4j.config_file");
Log4JRepositorySelector.init(config, configFile);
log = Logger.getLogger(getClass());
log.debug("logging initialised");
[snip]
}
}
This doesn't work:
public class LoginFilter
implements Filter {
private Logger log = Logger.getLogger(getClass());
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest)request;
log.debug("uri = " + req.getRequestURI());
[snip]
// otherwise continue
chain.doFilter(request, response);
}
}
Can someone shed some light on this please?
