log4j in Struts
I am trying to use log4j in a Struts application that I am developing. I have a utility class in which I initialize my logger in a static block. I have something like this:
public class UtilClass {
private static String dateFormat = "dd-MMM-yyyy";
private static Logger logger = Logger.getLogger("MyLogger");
static {
RollingFileAppender appender = null;
try {
ResourceBundle bundle = ResourceBundle.getBundle(Constants.APPLICATION_RESOURCE);
PatternLayout pl = new PatternLayout("%d - %m%n");
appender = new RollingFileAppender(pl, bundle.getString("logFile"));
appender.setMaxBackupIndex(5);
appender.setMaxFileSize("10MB");
logger.addAppender(appender);
logger.setLevel((Level) Level.toLevel(bundle.getString(
"loggerLevel")));
} catch (Exception e) {
e.printStackTrace();
}
}
public static void addLog(String msg) {
logger.error(msg);
}
public static void addLogInfo(String msg) {
logger.info(msg);
}
public static void addLogDebug(String msg) {
logger.debug(msg);
}
...
}
Then, when I want to log an event in another class I simply use the static methods in UtilClass, like:
catch(Exception e) {
UtilClass.addLog( "Message: " + e.getMessage());
}
However, it doesn't seem to work. When I run the app, I get two warning messages:
1. log4j:WARN No appenders could be found for logger (org.apache.struts.util.PropertyMessageResources)
2. log4j:WARN Please initialize the log4j system properly.
This is my first attempt at log4j, so I am a little befuddled.
I am using an OC4J app server
Any suggestions would be much appreciated.
Thanks
