Hi Jeff,
Thanks for responding. I have written a simple Listener class that is
loaded at startup by Tomcat, which makes a static logger available to
the web-app (both as a static getter and a servlet context param), and
I have no problem using it from other areas such as jsp or servlets or
non-maverick pojo's. The logger itself is a simple custom jdk1.4 logger
(ie not log4j) and uses a very simple formatter. It uses a FileHandler
that points to a txt file in WEB-INF. No errors appear to be generated
and as far as I'm aware there are no weird classloader issues.
here is the Listener that creates the logger:
public class SiteLogger implements
ServletContextListener {
private static Logger logger;
public static Logger getLogger() {
return logger;
}
public void
contextInitialized(ServletContextEvent e) {
ServletContext sc = e.getServletContext();
// get logger instance.
logger = Logger.getLogger("global");
// TODO: Should really be injected.
logger.setLevel(Level.INFO);
try {
FileHandler fh = null;
String root = sc.getRealPath("/");
// TODO: Again value should be injected.
fh = new FileHandler(root+"WEB-INF/log.txt");
CustomFormatter cf = new CustomFormatter();
fh.setFormatter(cf);
logger.addHandler(fh);
} catch(IOException ioe) {
System.err.println("Can't load logger" + ioe.getMessage());
}
sc.setAttribute("fw.logging.SiteLogger", logger);
}
...etc
here is the web.xml entry for the listener:
fw.logging.SiteLogger
here is the code that does the logging in the controller's perform()
method:
import fw.logging.SiteLogger;
...
SiteLogger.getLogger().log(Level.INFO, obj);

I'm pretty sure that's going to be far too general a question. You
need to explain how your logging framework works if anyone's going to
be able to help you. Does it do anything weird with classloaders?

Hi,
I am trying to log via a standard custom logger from within the
perform() method of a controller that extends ThrowawayBean2. HOwever
nothing is being logged. My logging framework seems ok as it is
logging elsewhere in the app. Anyone come across this before?
thanks.
