When you instantate your logger maybe do it like this....?
private static Logger logger =
Logger.getLogger("com.packagename.packagename.viewhelper.xxxx.class");

Subject: wrong class and method information when logging
Hi,
I am new to using log4j. I want to append the current userid to the output
in the logfile. I am using the following code to store the userid:
public class ThreadProperties {
public static final long NO_USER_ID_AVAILABLE = -1;
private static ThreadLocal currentUserID = new ThreadLocal() {
protected synchronized Object initialValue() {
/*
* our initial value will be a null
* we do not want to return a default value
*/
return new Long( NO_USER_ID_AVAILABLE );
}
};
/**
* Used to set the thread scoped userID variable.
* @param id int
*/
public static void setCurrentUserID(long id) {
/*
* return the userID available through the static userID ThreadLocal
object
*/
currentUserID.set( new Long(id) );
}
public static long getCurrentUserID() {
/*
* return the userID available through the static userID ThreadLocal
object
*/
return ( (Long) (currentUserID.get()) ).longValue();
}
}
My Logger is as follows:
package com.mycompany.util.logger;
import org.apache.log4j.Logger;
public class OptimadLogger{
public static final String EMPTY_STRING_WITH_SPACE = " ";
public static final String EMPTY_STRING = "";
private Logger instanceLogger =null;
private String getIDString(){
StringBuffer sb = new StringBuffer();
sb.append(" [User ID=");
sb.append(ThreadProperties.getCurrentUserID());
sb.append("]");
sb.append(EMPTY_STRING_WITH_SPACE);
return sb.toString();
}
private void setInstanceLogger(Logger aLogger){
instanceLogger = aLogger;
}
public static OptimadLogger getOptimadLogger(String logger){
OptimadLogger log = new OptimadLogger();
log.setInstanceLogger(Logger.getLogger(logger));
return log;
}
public void debug(Object ob){
instanceLogger.debug(getIDString() + ob);
}
public void debug(Object ob, Throwable t){
instanceLogger.debug(getIDString() + ob, t);
}
/** Other logging methods left out*/
public boolean isDebugEnabled(){
return instanceLogger.isDebugEnabled();
}
}
The above logs the userid to the logfile but I loose the class and method my
logger was called in. The trace shows:
2003-07-16 15:38:33,165 [DEBUG] OptimadLogger.debug - [User ID=4] SQL
statement closed
as opposed to :
2003-07-16 15:38:33,165 [DEBUG] MyDAO.myMethod - [User ID=4] SQL statement
closed
can i tell log4j to record the class that called my logger as opposed to the
logger itself?
thanks
