Thinking about log4j performance
It's known that log4j has a good performance even 'on an AMD Duron clocked at 800Mhz running JDK 1.3.1' machine. If I have lot of appenders, for example, a socket appender, which will cost 0.1 second to communicate with the socket server, and there's still a file appender in the system all the same. My puzzle is that, will socket appender and file appender work at the same time? Or run socket appender first, and AFTER socket appender done, file appender later. And the system will hold on till all the appenders are invoked? Might it can be explained in the below assumption codes. Assumption methodA(); //(1) logger.debug(hello,log4j) //(2) hold on till all appenders are invoked one by one? methodB(); //(3) Best Regards Xi Yuxiang System Architect Maveo Systems Limited - www.maveosystems.com Email: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Oh joy. - I have Tomcat 4.1.12 with 1 context (my application). you should upgrade. 4.1.29 is out and Tomcat-5, my personal favorite, is just about to be fully released as 5.0.15 (or whichever version they decide). - In my application I have * WEB-INF/lib/log4j.jar (latest stable) * WEB-INF/classes/log4j.properties sounds about right. - In the Tomcat directory is no log4j.jar or properties. in the Tomcat directory? What does that mean? TOMCAT_HOME? common/classes? Where? Also, it would be hard to guarantee that there is no log4j.properties anywhere in a place where Tomcat can see it such as an arbitrary jar file in common/lib or shared/lib. You never know. That's why I recommend against counting on auto-configuration. It is there for convenience, but doesn't always provide what you need. Anyway... Now, if I start Tomcat with -Dlog4j.debug=true, I get NO debug output nor is my log4j.properties loaded, but I do not get log4j error messages about needing a log4j.properties (so it did find one), and there is log4j output being generated... Why don't I get debug output? That's a bit odd, I must say. If I copy a log4j.jar into Tomcat/server/lib, I do get debug output, but then it says: log4j: Could not find resource: [null] server/lib is not a place to put stuff for your webapp to see. Even much of Tomcat's common stuff can't see server/lib. for instance, common/lib can't see server/lib, although the converse is true. Personally, I always put log4j.jar in common/lib and a log4j.xml (for server logging only) in common/classes. I then have the choice of putting log4j.jar and log4j.xml in each webapp or just have log4j.xml in each webapp, do manual configuration, and use a repository selector to use the common log4j.jar in common/lib. Why isn't it looking into my web-inf/classes? It should, I'm not sure why it isn't. Webapps look in the WebappClassLoader first before looking in a parent classloader (note that this is opposite to normal Java2 classloading behavior where the parent is usually searched first). BTW, are you starting Tomcat up using the standard startup scripts or starting Tomcat as a service? Because if it is the latter, then you should check your system classpath. The startup scripts eschew the system classpath. Running as a service won't. The best policy here is to clean up your system classpath. Mine is a single period and nothing else which avoids this whole issue whether or not I start via scripts or as a service. Please, tell me I'm not stupid. Again, you're not. This classloader stuff can drive one insane.

RE: LoggingEvent.locationInfo
Hi, Andreas New a Throwable() will create the full stack trace information in the throwable instance. The log4j parse the stack trace and get the LocationInformation. But it's of no use to the class in the same package with LoocationInfo(or LogEvent) It's heavy burden to create lots of exceptions, so I do not recommend you use this one if your system are time-critical.

Subject: How do I set the character encoding ?
Hello,
I am new to the list, and to log4j.
It seems that log4j writes log in the encoding specified
by file.encoding property. Is there a way to override this?
I would like to write my log files in UTF-8 encoding
regardless of the platform's locale setting.
Experimenting with Sort.java sample program, I thought
this would work:
static Logger logger = Logger.getLogger(Sort.class.getName());
Enumeration appenders=logger.getAllAppenders();
if(appenders!=null){
if(!appenders.hasMoreElements()){
System.out.println(getAllAppender() returned zero-count
Enuml.\n);
}else{
while(appenders.hasMoreElements()){
Object o=appenders.nextElement();
if (o instanceof WriterAppender){
((WriterAppender)o).setEncoding(UTF-8);
System.out.println(setEncoding called.\n);
}
}
}
}else{
System.out.println(getAllAppender() returned null.\n);
}
But it doesn't because getAllAppenders() returns the NullEnumerator.
I am actually hoping that this can be done in configuration, like:
log4j.appender.R.encoding=UTF-8
Is there such luck ?

Mapped Diagnostic Context in Struts Action Class
Hi, this is a combination question about both log4j and struts.
For the MDC is managed on a per thread basis, we can use it to log the user
IP address in the web application.
While, as I remember, struts action class is designed to be thread-safe.
If I try to log the user IP address in the execute () method of struts
action class,
For example
public ActionForward execute(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest request, HttpServletResponse response)
throws Exception {
String username=session.getAttribute(user);
MDC.put(userip,request.getRemoteAddr());
logger.info(username+ login);
..
}
Will the unexpected case happen?
1. UserA from 192.168.0.1 login, and the MDC put 192.168.0.1 to the MDC
2. UserB from 192.168.0.2 login, and the MDC put 192.168.0.2 to the MDC(now
the userip in MDC is updated)
3. UserA executed the code logger.info(username+ login);
4. UserA executed the code logger.info(username+ login);
so the log4j output maybe look like
[192.168.0.2] UserA login
[192.168.0.2] UserB login
Actually the assumption is
[192.168.0.1] UserA login
[192.168.0.2] UserB login

can log4j configuration file be sepearted into two...n files?
Hello I have a question on the separation of log4j configuration file. As in a web application, I try to assemble all the customer changeable properties (for example the log file location) into one file - customer.properties. The customer can decide where to log file can be placed, by changing customer.properties. maybe he will be confused by looking at the log4j.xml file. That's why I want to separate the log4j.xml into two or more files. It's easy to separate log4j.properties, as there's a method file:///I:\developer\jakarta-log4j-1.2.8\docs\api\org\apache\log4j\Property Configurator.html#PropertyConfigurator() PropertyConfigurator. file:///I:\developer\jakarta-log4j-1.2.8\docs\api\org\apache\log4j\Property Configurator.html#configure(java.util.Properties) configure( http://java.sun.com/products/jdk/1.3/docs/api/java/util/Properties.html Properties properties) to load all the properties. But now I want to transform to log4j.xml, to enjoy the convenience of XML configuration (FILTER and more). I have an idea of converting the customer.properties to customer.xml. But is there a way of keeping the file location in customer.properties(said above), and integrate the other part of log4j.xml? Xi Yuxiang System Architect Maveo Systems Limited - www.maveosystems.com

Hi,
The log4j.properties file is as shown below. I have 2 appenders set and
wish to log the different levels to different places.

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

(timestamp,priority,filename,msg) VALUES ('%d', '%p', '%c', '%m')
log4j.rootLogger=ALL, stdout
log4j.logger.database=ERROR, R
The problem I am having is that all the messages are getting logged at
the console but none of them are getting logged to the database.
If I change the file a little bit and set the root logger to log at
both the places like:
log4j.rootLogger=ALL, stdout, R
Now all the messages are logged in both the places. Could anyone please
tell me if the above methods for having multiple loggers is correct.

Setting Threshold=ERROR can force log4j to log the higher priority loggings
of ERROR FATAL, as demonstrated by Adrian Janssen said below.
But I'm wondering to know if there's a way to log only ERROR loggings, no
FATAL in one appender. That is, one appender to log only one level; not to

Questions on Log4J LocationInformation
Log4j has provided the interface org.apache.log4j.spi.LocationInfo.java, which give us the chance to get where log event delivers from. For example, if we use log4j.appender.Console.layout.ConversionPattern=%l %m%n We can get information like below on the console screen JAVA DEBUG test.TestLog.main(TestLog.java:17) this is the log information But because the log4j manual tell us that using %l will extremely slow down the speed of the whole application, so I just wonder to know how deep does this affects our system, is there a way to measure the performance? Thanks in advance. Best Regards Xi Yuxiang - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: can't get log4j under tomcat working
There's a console appender, which will output log information to the console. If you are running it in linux, you could output the console information to a file. Best Regards.

RE: NullAppender for Download
If you set the log level to OFF, that is the same to null appender. Best Regards.

As the logger cannot write to CD, I'm looking for the org.apache.log4j.performance.NullAppender class to prevent access-denied-errors. I found several java-doc descriptions for the NullAppender but no site where I could download the class. Can anyone send me the file or a link to it? Did you see the part of the JavaDoc, in red font, that says: The org.apache.log4j.performance.NullAppender class is intended for internal use only. Consequently, it is not included in the log4j.jar file. ;) ;) There's the org.apache.log4j.varia.NullAppender class that does come with the distribution. Neither I think is a good idea: why not just use a console appender instead of the null one?

RE: Log4j within JSP
Actually, there's no difference in using log4j in JSP. Just add the log code in your JSP scripts. Like logger.debug(your.message); -Original Message- From: Scott Burns [mailto:[EMAIL PROTECTED] Sent: 2003618 10:59 To: Log4J Users List Subject: Log4j within JSP Any Suggestions for using log4j from a JSP?
