RE: Help with RMI
Thanks gurus (Luis -n- Thomas ) That oughtaa get me started ;-). I'll try it out. Regards SimpleMortal - Original Message - From: Thomas Muller [EMAIL PROTECTED] Date: Wed, 16 Jul 2003 19:16:32 +0100 To: Log4J Users List [EMAIL PROTECTED] Subject: RE: Help with RMI Simple, There are several solutions to your problem. The simplest is to have one or several overloaded log methods defined in your remote interfaces, and your client can remote-log via these interfaces. A better solution might be to have an RMIAppender that communicates with a remote object which handles the LoggingEvents. I took the liberty to scratch a few lines to start you on the second approach. Please find attached file RemoteLogger.java, RemoteLoggerImpl.java and RMIAppender.java. Here is how you do it: 1. On the server side you need to register the RemoteLoggerImpl in the Registry, e.g. during application startup. 2. On the client side you can add the RMIAppender to any Logger you like (in the log4j.properties or log4j.xml file). The RMIAppender accept these parameters: host, port, remoteLoggerRegistryName. They all have sensible default values. 3. The server side log4j configuration file must pair sensible Loggers and Appenders. If you e.g. have a client side Logger named x.y.z, you add a Logger x.y.z and pair it with e.g. a FileAppender. Note: The code is totally untested, but it does compile without errors. It does by _no_ means hold up to production quality standards.

Re: help debugging config file
Erik Price wrote: Hi, Can anyone see a problem with my log4j configuration? This exact same configuration works fine on another project, and if I change the appender to a ConsoleAppender then the output *does* get logged to stdout, but for some reason this configuration simply writes an empty log file named tests.log: Pardon me. With Inder's help I was able to deduce that the problem is that my unit tests were overwriting the file. I had forgotten that the append=false setting is ideal in [my] production environment, but in testing, it doesn't help very much for generating logs!! ;) Erik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Help with Logging (1.2.7)
I had the same problem, I found out that jboss has its one log4j.properties
file in the jar file jbossall-client.jar.
(that's were the 09:20:47,919 INFO [STDOUT] is coming from).
I solve it by placing the location of my log4j.properties in the CLASSPATH
before the above jar file.
Hope this will help.

Thanks for the suggestion. I already have all loggers additivity set to
false, but my logging to the category still is appended to a JBOSS INFO
message before being displayed.
I must be doing something fundamentally wrong. Does anyone have a clue?
I've read all the threads about this from the archive. It has given me some
insight, but hasn't addressed my issue.
Can somebody explain why I see the following behavior:
JBOSS logging setup to log to console and file. I define a new category in
my application logging config file then attach new console and file appender
to the category. My application then logs to the category. If I make the
following call: myCategory.debug( sometext );
Why does this get appended to a [INFO] message before being displayed to the
console. This is not an additivity issue as I only get one entry in the
log.
If someone could help me understand why I see log entries like the following
with my setup I might be able to fix it. Where is the 09:20:47,919 INFO
[STDOUT] coming from Everything after that is the data from my call to
log to the category.

Sorry, cannot help you there. As I mentioned I have zero experience using JBOSS. For the console one, I would suggest that it really isn't that big of a deal (but thats just me). For the file appender, however, I cannot begin to fathom how they could be catching those. Might want to ask these on the JBOSS mailing list to see if any over there have come to terms with this.

RE: Help with Log4j automatic header generataion
I guess it depends on what the user really wants, but it seems that there should be some checking (or an option) to alter the behavior of writing a header to anything but a fresh file. I could see where you might want a continous log regardless of shutdown, and also where you may want a header to signal the restart of the log -Original Message- From: David Sanders [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 30, 2003 6:02 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: Help with Log4j automatic header generataion http://www.mail-archive.com/log4j-user@jakarta.apache.org/msg05953.html Thank you for the solution. One problem, though: If the logging process (JVM) is stopped and restarted, a 2nd header is written to the existing file. Example: - using DailyRollingFileAppender - logged record #1.

Sorry, mistake in my xml. Try this instead: logger name=Request additivity=false level value=debug/ appender-ref ref=Request/ /logger root priority value=debug/ appender-ref ref=DailyLog/ /root You can tell how often I actually change additivity.

Configuring log4j with 2 or 3 different configuration files, the last configuration file will be in affect. You should probably combine the configuration files into a single file, and then add the following: logger name=Request priority value=debug/ appender-ref ref=Request/ param name=Additivity value=false/ /logger root priority value=debug/ appender-ref ref=DailyLog/ /root This makes it so that the logger Request only logs messges to the appender Request.

Re: Help !
Bonjour Sébastien
I'm new to log4J as well, but what you're doing seems very complicated. Why
do you do all the configuration in java code? I do it all in the config
file.
My code looks instance like:
public class GererPage extends Action {
static Logger logger = Logger.getLogger(GererPage.class.getName());
public GererPage() {
logger.debug(creating new GererPage - + this.toString());
}
bla,bla bla
}
I also have once in my application:
void init() {
PropertyConfigurator.configure(myfile.lcf);
}
This works fine to log messages. I haven't figured out whether you are
trying to do something else in your trace function.
Bonne chance,
Neil

Hi,
We're working on a java web site and we'd like to use log4j in order
to log the error.
We have made a class to implement the init of log4j. Here the source of
this
class :
private Logger logger ;
public Trace(String class_name) {
logger = LogManager.getLogger(class_name);
Layout layout = new PatternLayout(%d{MMdd-HH:mm:ss} %m%n);
logger.addAppender(new ConsoleAppender(layout,
ConsoleAppender.SYSTEM_OUT));
logger.setLevel(Level.DEBUG);
try {
logger.addAppender(new FileAppender(layout, (String)
Ecx_constants.getInstance().get(log4j_fileTrace), true));
} catch (IOException e) {
}
To log something :
Trace t = new Trace(this.getClass().toString()) ;
t.debug(My message);
The first time, we call the page, the log contain the good thing :
20030116-12:00:00 My message
But the second time we call the page, 30 sec after, we have in the log:
20030116-12:00:00 My message
20030116-12:00:30 My message
20030116-12:00:30 My message
== the log appears 2 times !
the third time, the log appears 3 time, etc..
Can you help us please ?
Thx

RE: Help !
Step-by-step what is happening here is:
First-call:
1) A logger with a name matching the given class_name does not exist, so
log4j creates it.
2) Two appenders are added to the logger (a console appender and a file
appender).
Second-call:
1) A logger with a name matching the given class name already exists (it was
created above), so that logger is returned (including the two appenders
previously attached)
2) Two appenders are added to the logger (a console appender and a file
appender).
Etc...
Assuming that there is a vaild reason you need to wrap all these log4j calls
inside your own hand-rolled class, then try something like the following
code change in the constructor:
public Trace( String class_name )
{
if (!LogManager.exists( class_name ))
{
logger = LogManager.getLogger(class_name);
Layout layout = new PatternLayout(%d{MMdd-HH:mm:ss} %m%n);
logger.addAppender(new ConsoleAppender(layout,
ConsoleAppender.SYSTEM_OUT));
logger.setLevel(Level.DEBUG);
try
{
logger.addAppender(new FileAppender(layout,
(String)Ecx_constants.getInstance().get(log4j_fileTrace), true));
}
catch (IOException e)
{}
}
}
But the better solution is to perform initialization of the log4j library
through config files.

RE: Help !
Thx a lot !!!
the problem was that we always add the appenders. So, the first time it's ok
but after, we always add the two appenders.
Now we use the exists method in order to know if the logger exists.
if not, we create the logger and then add the appenders.
if exists, we do nothing !
You ask why we make the config in the java code.
For our java web site, we use Weblogic and ear file.
We have to specify and modify easily some parameter without deploying the
ear file like the level,
the file where we write, the repository where is the xml containing the
message.
But with a config file, we can't change easily this parameters, we have to
deploy the ear, make the modification
and then rebuild the ear !
Thx a lot for your help.

Step-by-step what is happening here is:
First-call:
1) A logger with a name matching the given class_name does not exist, so
log4j creates it.
2) Two appenders are added to the logger (a console appender and a file
appender).
Second-call:
1) A logger with a name matching the given class name already
exists (it was
created above), so that logger is returned (including the two appenders
previously attached)
2) Two appenders are added to the logger (a console appender and a file
appender).
Etc...
Assuming that there is a vaild reason you need to wrap all these
log4j calls
inside your own hand-rolled class, then try something like the following
code change in the constructor:
public Trace( String class_name )
{
if (!LogManager.exists( class_name ))
{
logger = LogManager.getLogger(class_name);
Layout layout = new
PatternLayout(%d{MMdd-HH:mm:ss} %m%n);
logger.addAppender(new ConsoleAppender(layout,
ConsoleAppender.SYSTEM_OUT));
logger.setLevel(Level.DEBUG);
try
{
logger.addAppender(new FileAppender(layout,
(String)Ecx_constants.getInstance().get(log4j_fileTrace), true));
}
catch (IOException e)
{}
}
}
But the better solution is to perform initialization of the log4j library
through config files.

RE: Help !
I also use Weblogic and war/ear file deployment. However, I just wrote a
simple little set of JSPs to allow dynamic overrides of the level for
defined appenders. This is particular useful for things like user-specific
loggers...
However, I let log4j initialize itself initially from its config files.
Just some thoughts...

RE: Help with Log4j automatic header generataion
Very simple -
Just extend PatternLayout (thats what your example looks like), or any other
layout and over-ride the getHeader() and/or getFooter() methods. Then just
name your class as the layout in the config file.

It is a bad idea to extend Logger to support new level types. You should use the Logger.log method instead as in: logger.log(Your.custom.level, your message); The problem stems from the fact that the logger repository might be set by the EJB Container and not your application. In that situation the logger instances returned by Logger.getLogger might be incompatible with what your application expects, i.e. you will get a NoSuchMethodException when your application accesses info+() or info-() methods. -- Ceki -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: Help to configure Log4j with example
First, Ceki is right. There is a lot of good information in the short manual. That article has a great introduction to logging generally and nicely goes into detail about the major pieces of log4j. I don't think it needs to be broken up. But I also agree that first- and second-time users would benefit by having the how-to recipe to get started, with follow ups on each of the major areas, also in a cookbook style approach. I'd certainly be willing to take a stab at those if I'm not stepping on anyone's toes. Different people learn in different ways, so having a 'how to' recipe approach as well as the short manual would serve log4j users well. I agree also that the how-to should end with a where to go from here... set of links. But I think the very next level would be just a step beyond the beginner stuff and make the write-your-own stuff a subsequent level. So, for example, the first how-to has among its next steps links a link to a document on Appenders and what they are and how to use the existing ones. That in turn could link to how to write your own Appenders.

Dave, if you have time to cook something up, go for it. I think you are on the right track. We can keep our toes out of harms way.

Maybe we need to redesign the layout of the web pages so folks can find things better, but I think your point about people approaching new stuff differently is valid.

RE: Help to configure Log4j with example
Hi all, I think it all boils down to this. 1. If I need Log4j just as a logging utility and I need it FAST, a short cookbook would be of great help 2. Provided the powers of Log4j mentioned in the introduction, Where-To links would be of great help if I want to extend usage in future. So, I think we can stop further discussion on this and get back to implementing it :-) -Cheers Gautham -Original Message- From: Mark Womack [mailto:[EMAIL PROTECTED]] Sent: Friday, April 12, 2002 9:46 AM To: 'Log4J Users List' Subject: RE: Help to configure Log4j with example Dave, if you have time to cook something up, go for it. I think you are on the right track. We can keep our toes out of harms way. Maybe people just haven't found Ceki's article and taken the time to read it. Maybe we need to redesign the layout of the web pages so folks can find things better, but I think your point about people approaching new stuff differently is valid. I know it took me some time to get my feet on the ground, so whatever we can do to help in this regard will potentially increase the adoption of log4j and the level of dicussion on the mailing list. thanks, -Mark -Original Message- From: Dave Bender [mailto:[EMAIL PROTECTED]] Sent: Friday, April 12, 2002 7:29 AM To: Log4J Users List Subject: RE: Help to configure Log4j with example First, Ceki is right.

RE: Help on XML config files
Thanks for your quick response. For the most part, I really like the log4j
library. And, when I run the program with -Dlog4j.configuration=log4j.xml
it does indeed work. (I was able to do this prior to the email.) However,
rather than doing the log4j default initialization with
-Dlog4j.configuration, I'd like to be able to specify the file to the
program and call the PropertyConfigurator.configure() passing it the file
name -- a system that works fine with the old style configuration files.
Here's the code. Can I pass an XML file to
PropertyConfigurator.configure()? Do you see something else I'm doing
wrong?
Thanks again,

Re: Help Needed!
Hi Mark,
I am using the FileWatchdog and PropertyConfigurator as suggested by u. But I am not able to fix the puzzle. What I have now is individual parts and need your advice on placing things together.
I want to use RollingFileAppender with run-time configuration of the debug, errors and info messages (each type having a file). Now how to invoke the PropertyConfigurator class as well as the classes extended from FileWatchdog and PropertyConfigurator ? Also how to load the log4j config file?
We are using WeblogicServer6.0sp1 running 2 webapps. We need to log messages of this webapps to seperatelly and in three seperate files debug, errors and info respectively .
Can u give me soem pointers and if possible sample code ?
Thanx in advance

You don't need to jump through this many hoops to get this behavior - there
is an easier way to achieve dynamic, run-time re-configuration using
standard config files. Specifically, you don't need to roll your own file
listener - Log4J already has one. To do this, you subclass FileWatchdog and
the appropriate PropertyConfigurator. For example, in our apps, we subclass
FileWatchdog and DOMConfigurator. Then, you override doOnChange() and
configureAndWatch(), in your FileWatchdog sub-class and your
PropertyConfigurator sub-class, respectively. In the PropertyConfigurator
sub-class's configureAndWatch() method, you set things up to use your
FileWatchdog sub-class (instead of a standard one), and in the doOnChange()
method of your FileWatchdog class, you call
BasicConfigurator.resetConfiguration(). In your application, you then need
to initialize Log4J by using your PropertyConfigurator class instead of the
standard one, i.e.;
"M2TraceDomConfigurator.configureAndWatch(configFile,configReloadDelay);"
and not "DOMConfigurator.configureAndWatch(configFile,configReloadDelay);".
Below are code snippets for the relevant spots from the implementation we're
using here - works fine. This question has already been answered at least
once on this list, primarily by Ceki and Jim Moore - you should check the
list archives for more details.
Cheers,
Mark
public class M2TracePropertyWatchdog extends FileWatchdog{
blah, blah, blah
public void doOnChange() {
BasicConfigurator.resetConfiguration();
new DOMConfigurator().doConfigure(filename,
Category.getDefaultHierarchy());
}
blah, blah, blah
}
public class M2TraceDomConfigurator extends DOMConfigurator {
blah, blah, blah
public static void configureAndWatch(String configFilename, long delay) {
M2TracePropertyWatchdog pDog = new
M2TracePropertyWatchdog(configFilename);
pDog.setDelay(delay);
pDog.start();
}
blah, blah, blah
}
Keep the Faith! Good Happens!!

Hi all,
I am looking in to the log4j manual.In the following example where

PropertyConfigurator.configure(args[0]).
But i haven't seen the file name and location of it. Can anybody tell
Where is he specifing the location of the file.
import com.foo.Bar;
import org.apache.log4j.Category;
import org.apache.log4j.PropertyConfigurator;
public class MyApp {
static Category cat = Category.getInstance(MyApp.class.getName());
public static void main(String[] args) {
// BasicConfigurator replaced with PropertyConfigurator.
PropertyConfigurator.configure(args[0]);
cat.info(Entering application.);
Bar bar = new Bar();
bar.doIt();
cat.info(Exiting application.);
}
}
args[0] refers to the first command line parameter given to your
application. So if your application is 'MyAapp' and configuration info
is in 'MyApp.config' then you would bring up the app with
java MyApp MyApp.config
Cheers

Categories inherit their priority and appenders. You do not need to
define them explicitly. For example, this category element
category name=com.divine additivity=true
priority value=debug/
appender-ref ref=TEMP1/
/category
is superfluous. It will actually cause the TEMP1 appender to be used multiple
times. I also suggest that you read the section on appender additivity in
the log4j manual. Hope this helps, Ceki

Hello Scott,
Categoty.getInstance takes a string or a class. Assuming that the
MyFooBar class is in the ch.qos package. The following a strictly
equivalent:
Category x = Category.getInstance(ch.qos.MyFooBar);
Category x = Category.getInstance(MyFooBar.class.getName());
Category x = Category.getInstance(MyFooBar.class);
Category cat = Category.getInstance(NameOfTheServlet.class.getName());

Re: Help needed : Log4J with servlets
Amit,
Here is some sample code of how we have used Log4J in servlets.
public class StartupServlet extends HttpServlet
{
static Category cat =
Category.getInstance(StartupServlet.class.getName());
public void init()
{
URL propsURL = Util.configureLog4j();
PropertyConfigurator.configure(propsURL);
cat.info( Starting the app);
}
...
}
//here is the Util class
public class Util
{
public static URL configureLog4j()
{
ClassLoader loader = Thread.currentThread().getContextClassLoader();
URL propertiesURL = loader.getResource(log4j.properties);
return propertiesURL;
}
}
Thanks

I need to use XML file as configuration file which should be parsed

and necessary logging should be done.
Currently I've used the following code (inside doPost method):
---
static Category cat =
Category.getInstance(assign4Servlet.class.getName());
try
{
URL url =
getServletConfig().getServletContext().getResource(/sample1.xml);
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
factory.setValidating(true);
DocumentBuilder builder =
factory.newDocumentBuilder();
Document doc =
builder.parse(url.toExternalForm());
DOMConfigurator.configure(doc.getDocumentElement());
--

--
cat.info(Inside doPost method of the servlet);
cat.debug(Inside doPost method of the

Re: Help on property file settings for Appenders and Layouts
Maybe it would be useful for us to have a convention of listing all configurable properties of components in the class-level javadoc comment. For each property there'd be the name and a link to the associated setter method. I s'pose not all setters are necessarily intended for configuration. Anders Ceki Gülcü wrote: At 13:27 24.05.2001 +0100, you wrote: Hi all, I'm just trialing Log4J as a new logging solution for our system and I'm trying to configure the appenders and layouts by property file. Is there any documentation of the possible property settings for each of the Log4J classes (e.g DailyRollingFileAppender and HTMLLayout). Looking through the exxamples they show a few of the settings but not all of them, where would I find the rest? regards, Mike Hurd This is a new FAQ entry: What are the configurable options for FooBarAppender? Log4j uses JavaBeans style configuration. Thus, any setter method in FooBarAppender corresponds to a configurable option. For example, in RollingFileAppender the setMaxBackupIndex(int maxBackups) method corresponds to the maxBackupIndex option. The first letter of the option can be upper case, i.e. MaxBackupIndex and maxBackupIndex are equivalent but not MAXBACKUPIndex nor mAXBackupIndex. Layouts options are also defined by their setter methods. Same goes for most other log4j components. Hope this answers the question.

If JMS is a possibility for you, it makes an excellent way to build a logging framework. log4j supports it out of the box, which is nice. What I did for our environment (J2EE based) is build some simple wrappers around log4j (handling things like configuration) for the producer end, and using log4j to send everything to a JMS Topic. One or more message receivers then subscribes to the Topic and handles the messages. In our case, I built one receiver (somewhat like the JMSSink example code) which sends messages to a file. Another runs in a servlet allowing access to the last 500 log messages via a browser. JMS makes a pretty flexible framework to do this sort of thing.

Re: help with Wrapping/Buffering
Hi Scott, I'm not sure you completely understood my problem (or perhaps I didn't understand your answer!) I'll try to restate the issue again. In order to avoid having huge log files full of unneeded information, I am going to store the log items for a session in a buffer. The items in this buffer may be discarded if there are no problems, but if there is an error, I'd like to output the contents of the buffer to a file. My problem is that if I handle the buffering before even touching log4j, then later pass the contents of the buffer through log4j I will not be able to retrospectively work out %F,%L etc. My plan was to find this information and add it to the buffer myself. After sleeping on the problem, I have thought of a second possibility, and would be interested to hear if anything like this has been done before: I was thinking about having some sort of BufferAppender which could add the LoggingEvents to an array/vector then some trigger could be used to output this information to a file when necessary. One downside I can see with this is that if I've specified the BufferAppender as the appender for a category, I will lose the ability to specify where the information is passed after the buffer. Well, I've successfully managed to confuse myself. If anyone understands my problem, and can suggest a solution then please let me know.
