RE: JMSQueueAppender and Tomcat 4.1
Howdy, Make sure your initial context factory implementation is in WEB-INF/lib, and that you construct an initial context with the environment parameter (hashtable), not just new InitialContext(). In that environment, specify the factory class name and server JNDI URL. When you don't, you're using tomcat's default JNDI initial context factory implementation which can't talk to your IBM server. If you do the above, you'll be able to run with the Sun JDK (or any other). I suggest you read the JNDI documentation.

RE: Log output path problem
Howdy,
You need to specify the absolute path or use an environment variable,
such as one set to the server's home. Your current specification is
relative to the current working directory of the server, which varies
depending on how the server is invoked.

RE: Log output path problem
Howdy,
You're asking a number of questions in this one post.
This is weird. I had it working two hours ago with /web/WEB-
INF/logs/debug.log
as my output path. Now it's not working!!! I have to use the absolute
path
The above is an absolute path. It should work (provided you have
permission to write to this directory).
make logging working for now. Also it seems that if I use the relative
path /web/debug.log or just debug.log, things worke fine, but that's
not where I want it to go to.
I didn't say it wouldn't work: I said it would place the log file in a
path relative to the current working directory of the server. As you've
observed, this is not the desired behavior.
Could the same server invoke things differently? Man, what's the deal
with
Depends on the server. More likely, you started the server from
different directories.
setFile() anyway? Why it cannot create the path dirs if the path
doesn't
exist?
That's beyond the purview of log4j. The user is responsible for
configuration including the creation of directories. It is both common
and recommended to run Java with a security manager with specific write
permissions to the log file only, not anywhere else.

mail.jar shouldn't be in WEB-INF/lib as it is an endorsed library
(anything
java.* javax.*, org.xml.*, org.w3c.dom.*). Put it in
CATALINA_HOME/common/lib or endorsed. This allows Tomcat to use the
mail
api as well as your apps and will avoid troubles when/if the JDK
actually
includes the mail api (does the J2EE jar include it?). Of course,
this
probably isn't your immediate problem.
Is Log4j getting configured under Tomcat for you? That is, are you
getting
output in other appenders? If not, get that going first, and then
try to
get the Mail appender working. Where is
log4j.properties? WEB-INF/classes? Are you configuring it manually?
It
may have been in the classpath of your IDE, but not of your webapp.
Just
things to check out.

mail.jar shouldn't be in WEB-INF/lib as it is an endorsed library
(anything
java.* javax.*, org.xml.*, org.w3c.dom.*). Put it in
CATALINA_HOME/common/lib or endorsed. This allows Tomcat to use the
mail
api as well as your apps and will avoid troubles when/if the JDK
actually
includes the mail api (does the J2EE jar include it?). Of course,
this
probably isn't your immediate problem.
Is Log4j getting configured under Tomcat for you? That is, are you
getting
output in other appenders? If not, get that going first, and then
try to
get the Mail appender working. Where is
log4j.properties? WEB-INF/classes? Are you configuring it
manually?
It
may have been in the classpath of your IDE, but not of your webapp.
Just
things to check out.

RE: TelnetAppender generates NullPointerException
Hi, Let's stop the cross-posting to keep it on this (user, not dev) list. Looks like a bug. We probably need to look at TelnetAppender's shutdown or finalize method to make sure the socket is properly dismissed. I've never actually touched this appender's code. Please file this in bugzilla.

Though it's not included in the copy of my log4j.properties file I pasted into the beginning of this email thread, I did set the port with this line: log4j.appender.telnet.port=23 It made no difference. Actually, the problem appears to be that, when Tomcat reloads the web application after I run a build, TelnetAppender throws a BindException, with the message that the Address [is] already in use. Perhaps TelnetAppender is failing to dispose of its socket connection properly. If I shutdown and restart Tomcat, TelnetAppender works fine until the next time I reload the webapp, even without explicitly setting the port. If you like, I'll log a bug for this. Cheers, David P.S.

RE: Concurrency and performance degradation
Howdy, There is anyway to improve the performance in a concurrency environment (maybe defining a buffer size and have only one thread writing to the file and to the console? ) and prevent this concurrency problems?

RE: Concurrency and performance degradation
Howdy, I don't know, I haven't used it, as I haven't found the need for it. What I do in high-load environment is surround INFO and DEBUG level statements with is-enabled checks (Logger.isDebugEnabled() etc.), which reduces their overhead by nearly 100%. I don't have INFO and DEBUG enabled in production, so I don't suffer from high load at all.

RE: SMTP log4j question
Howdy, You need to access the SMTPAppender object and call its methods to dynamically change the properties like the subject line. How are you configuring log4j? If you know the name of the SMTPAppender, e.g. EmailAppender this is pretty easy. In your class, you would do something like: Logger rootLogger = Logger.getRootLogger(); SMTPAppender email = (SMTPAppender) rootLogger.getAppender(EmailAppender); email.setSubject(New subject line); email.setTo([EMAIL PROTECTED]); email.activateOptions(); If you don't know the name of the appender, or don't want to hard-code it, you can still do this. Use Logger.getAllAppenders() to get all the appenders, then iterate through them checking for appender instanceof SMTPAppender. A couple of notes since you mentioned you're new to this: 1. By default the SMTP appender will send out ERROR and higher messages only. If you want it to send INFO or lower, you will need to change its Threshold. Alternatively, you can write a custom TriggeringEventEvaluator for the appender to use. 2. If you have a small number of possible subject lines and to addresses, consider creating one SMTP appender for each combination.

RE: automatic reload
Howdy, A decent place to stop and start such threads in a servlet container would be the ServletContextListener. There is no static destructor, but you have Runtime#addShutdownHook which is suitable for this purpose as well. Create a little Runnable class with a reference to the Watchdog thread, add your Runnable as a shutdown hook, the JVM will run it (once) on shutdown, and your Runnable should interrupt the log4j Watchdog thread. This approach is good outside servlet containers as well.

In a stand alone application this is not such a problem, but in a container, where you have a separate configuration for each context (webapp0, I can't imagine where to hook that in, in a generic fashion.

Plugins are new to v1.3 and configurable from (at least xml) configuration files. So, you'll be able to define watchdogs in the configuration files. Plugins have some code to not stop/recreate running plugins during reconfiguration, so eventually if a watchdog is watching the configuration file that defines it, it will be maintained across reconfigurations, etc. Still working out some of those details.

RE: log4j losing log files
Howdy,
I don't have a solution to your problem, just a couple of
points/questions. ;)
The log4j1.2.8.jar file is in each webapp/WEB-INF/lib.
Each webapp has its own config file in webapp/WEB-INF/classes.
Good.
Each config file contains:
log4j.rootLogger=DEBUG
log4j.logger.dev=DEBUG, dev
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.appender.dev=org.apache.log4j.RollingFileAppender
log4j.appender.dev.File=C:/logs/dev_01.log
log4j.appender.dev.layout=org.apache.log4j.PatternLayout
log4j.appender.dev.layout.ConversionPattern=%d %X{RemoteHost} %C %-5p
%c
- %m%n
log4j.appender.dev.MaxFileSize=1000KB
log4j.appender.dev.MaxBackupIndex=100
Why define the stdout appender if you don't use it? Try removing it.
I haven't used the straight rolling file appender much. I mostly use
the DailyRollingFileAppender and haven't had a problem with it. Perhaps
you could give this a shot (again, as you say you've done it in the
past) and see what happens.
That way, I can get such a list of files as:
.log
.log.10
.log.11
.log.12
.log.13
.log.14
.log.15
.log.16
.log.17
.log.18
.log.19
.log.20
.log.49
.log.50
.log.51
.log.52
.log.53
I simply don't have any idea about what is going on. I spend a lot of
Add -Dlog4j.debug=true to your JAVA_OPTS when launching tomcats. Log4j
will then output internal debugging information to
$CATALINA_HOME/logs/catalina.out. Perhaps that will tell you something
useful, especially when you see the output generated when log4j is
rolling files over.

RE: log file permissions issue unix
Howdy, Log4j doesn't (and can't, even if it wanted to) set umask for the user. What I would is write a little unix script to invoke your application, but before invoking it do umask -S to verify the umask settings. The 02 your sysadmin set up is good. Since you're logging in as user tomcat, I assume you're running tomcat. Tomcat also doesn't (and cat) set umask for the user. I just checked, by the way, and I have the same behavior as you ;) Solaris 9, JDK 1.4.2, umask 02, log4j 1.2.8 on tomcat 4.1.27, and the log file is created as -rw-r--r--.

RE: Useful Object Renderers
Howdy, I'm wondering whether there are any useful object renderers that I haven't heard about, hopefully downloadable and easily integratable. Things I'd be looking to output without having to have long debugging logic in my code would be beans, JDBC ResultSet rows, and so on. Looking around the log4j codebase all I can see is one jms and one sax renderers, both rather basic. I'm sure people have done these for their own projects: they're not tough. They would be a nice contribution to the log4j sandbox for starters, maybe to be integrated into the core later on. It seems to me that this would be a very useful feature, improving the I prefer toString() methods that print all the information about the Object. Then I just call logger.debug(myObject) (which calls myObject.toString() down the line automatically) without writing or configuring any ObjectRenderers. But that's just me. However, there's the case where the object you want to log is not yours, e.g. java.sql.ResultSet, and if it doesn't have a good toString() method an ObjectRenderer would be perfect. In any case, I think the inclusion of more useful standard Object Renderers into the log4j codebase would be a very good thing for log4j, and I'm wondering why this hasn't been done yet. Are there any reasons that I'm not aware of? The usual reason: no one cares enough to contribute it? ;) I'm sure many have written their own. An ObjectRenderer to display your two cases: a Bean and a java.sql.ResultSet, wouldn't be that hard. They might have a couple of catches: the bean one would use reflection and probably wouldn't display information that can't be obtained via public methods (often one also wants private/protected field values displayed). The ResultSet one would have to be careful about resetting the ResultSet to its original condition when it's done rendering.

That decreases the overhead of writing the logging code. In exchange, it increases the overhead of running it.. Having very low overhead for adding logging code is very useful for me because I find myself working on other people's code a lot these days, and having to debug obscure problems with that code, I have been using log4j extensively to be able to follow what's going on. When adding log statements to large amounts of other people's code, the quicker it happens the best it is, in my experience.. Also when writing new code, you are more likely to add a log statement if it is a minor typing overhead (not to mention maintenance overhead) than not. I think the best solution might be to offer both possibilities, with the advice that if you are using the BeanWrapper, you should surround your log statement with an if (log.isDebugEnabled()) just like for string concatenation. On the other hand, if your bean implements LoggableBean you don't need to. I think that would give the best of both worlds, so when you're writing new code and you've got enough time you tag your beans as LoggableBeans, and when you're hastily adding log statements to someone else's code you can do so at the expense of an if() check with just a BeanWrapper. For the rendering of it, I think the idea when outputting a bean's fields to the log would be to show as much data as is available (within reason). Showing all available public bean properties, and maybe truncating the ones which are too long, would be the way I would expect such a renderer to work. Maybe this could be configurable from the log4j config file (log4j.renderer.bean.truncateLength?) Re: Generic ObjectRenderers Yes, I think so. It encourages more logging, which I think is a good thing, and removes logging display logic code. In an ideal world, log4j would become so closely integrated with java that much code (such as log.debug(entering);) would be automatically generated by the compiler or the VM! However until hell freezes over, the closest we can get is to make it really easy for people to write log statements and decrease maintenance time. If I have time I'll probably write a few generic object renderers when I'm home. The resultset one, for instance... most useful. Daniel PS: Btw, I've been meaning to say, thank you for writing log4j. I don't think I'd stand a ghost of a chance of finishing this project on time if it wasn't for log4j and the ease and flexibility with which I've been able to insert it all over the place to figure out what this code was doing (and be able to turn the debugging on and off at will).

It seems to me that this would be a very useful feature, improving the quality of usage practice with log4j. Just like layout patterns which allow you to log the locational information and avoid keeping such information in the log messages themselves (and thus having to maintain log messages such as log.debug(entering xyz.foo()) - much better as log.debug(entering)), standard object renderers reduce the complexity of the logging code. For instance, when wanting to output the contents of a bean, it would be nice to be able to just type: log.debug(myBean); Given the way object renderers work, that is of course not possible since beans are not subclasses of a particular class. One way to get around that would be for the logger to recognize an org.apache.log4j.BeanWrapper class so that this could be called like: log.debug(new BeanWrapper(myBean)); Creating a BeanWrapper for each bean to be logged is certainly one way to mark a bean for object rendering.

Agreed.
One way you could get around this is by making a (fairly simple)
servlet
that finds out where the log4j log file is, reads it and displays it,
on

app-server-independent

Even if deploy exploded (a feature servlet containers are not required

don't have write access under your webapp. The only directory you're
guaranteed write access to by the servlet specification is
javax.servlet.context.tempdir, which the container may clean on

Deciding where logs go is a server administrator decision: leave it up

My application needs to be deployable to both JBoss and Websphere
(and
possibly Weblogic in future). I am trying to use log4j in my app,
but
not
having any success, even only with JBoss.
Here's the deal--I want to include my own log4j.jar and log4j.xml in

log4j.xml
should only extend the configuration set up by JBoss. I don't want
to
add my
Appenders to the JBoss log4j.xml, I want them in my WAR so it
doesn't
depend
on the JBoss environment.
Here is a snippet of what I am doing in my init servlet:
String prefix = getServletContext().getRealPath(/);
String filePath = prefix + fileName;
System.out.println
(Log4JConfigServlet - initializing log4j using file: +
filePath);
try {
if (fileName.indexOf(xml) != -1) {
DOMConfigurator.configure(filePath);
} else {
PropertyConfigurator.configure(filePath);
}
Logger log = Logger.getLogger(Log4JConfigServlet.class);
if (log.isInfoEnabled()) {
log.info(Log4j initilized.);
}
} catch (Exception e) {
I see both the println and the initial INFO log message in the JBoss
console
log, but the two FILE appenders don't seem to be getting created--I
see
debug output from the initial JBoss configuration but there is no
debug
output when my config file is processed. (The full file is at the
end
of the
message).
This approach worked in JBoss 3.0.6 but it mysteriously stopped when
I
upgraded to JBoss 3.2.1.

I'm migrating my application to use log4j and need to
define a message
format that's compatable with an output format already in
place from my
original logging code. There are two formats I can't
currently seem to do:
1. I need to output the timestamp field as a two letter
day of week
string
-- Mo, Tu, We, etc.
2. I need to output the priority field as one character -
D, I, W, E, F
It seems the formatting directives in PatternLayout don't
allow for this.
They allow you to truncate fields to a max value, but
they're truncated
from the front, such that the directive '%.1p will
truncate INFO to 'O'
and not 'I'
I looked through the latest log4j code, and found a way
to patch this
functionality in by adding another formatting directive
similar to the '.'
but using a '#' instead.
It will similarly define the max length for a field, BUT it will
truncate the trailing characters rather than the leading
characters.
Examples:
%d{E} - Tuesday
%.2d{E} - ay (original truncate directive)
%#2d{E} - Tu (new truncate directive)
%p - INFO
%.1p - O
%#1p - I
In order to do this, I needed to make minor patches to 3 files:
- org.apache.log4j.helpers.FormattingInfo.java
- org.apache.log4j.helpers.PatternConverter.java
- org.apache.log4j.helpers.PatternParser.java
I'd be happy to submit these patches in the hopes that this
functionality could be added to the code base.
I'm assuming all I need to do is send mail to dev mailing
list with the
subject PATCH, or [PATCH], and then include in the
message the three
diff -c outputs?
Is this kind of functionality useful to others?
Is this the approach I should be taking when proposing changes?

So, please forgive if I sound really stupid putting forth my question(s). What we have done is we have added another level of abstraction between the application (some web app) developer and the log4j. We have written another class that imports log4j and other classes that are required for logging and written our own functions without any added functionality. That is, my debug will in turn call log4j's debug method. Another thing that has been added is: the isDebugEnabled () check before debug () of log4j is called. And similarly, isEnabledfor(level) for other levels. Now, my questions: 1) Is this added level of abstraction advisable? 2) Does the check before the call to log4j method serve any purpose (here in my case) in reducing the cost? This (in normal cases, not here) does prevent the cost of parameter construction when implemented in application directly (this I understand). But here, the parameters will be constructed, (so no savings on that side) when call is made to the debug () or any other method that we have implemented.

RE: bad days and good days
Howdy, I spent most of the day, going over the documentation on log4j and various ways of logging under Tomcat. Great article on commons-logging vs. Log4j :) I saw a reference to how different web-applications can have different log4j configurations in think again, but I am not sure where that is supposed to be described. I have yet to see any explanation of how that is supported. Simple: 1. Put log4j.jar in each webapp's WEB-INF/lib directory, and no where else. 2. Put log4j.properties in each webapp's WEB-INF/classes directory, and no where else. That's it. You can also doing it programmatically by writing an init servlet or servlet context listener that configure log4j. Then you can put the log4j.properties file anywhere under your webapp's root directory, and use ServletContext#getResourceAsStream(...) to get the file and feed it to PropertyConfigurator.

Howdy, I hate to be such a nitpick on this, and it's a matter of style only not substance, but in case you care, things that are static final should be capitalized, so if you have a private static final Logger it should be private static final Logger LOGGER = Logger.getLogger(some.name); If you leave it as logger (lower case), obviously it still works fine but tools like Checkstyle complain.

RE: Plans for supporting a build in level of trace
Howdy, TRACE or FINE is one that many seem to agree is sensible and required. That's the part I'm not convinced of. How do you support the above? I think the idea is, no matter how many or few default levels there are, the defaults should cover the range of the logging space completely. FATAL pretty much covers it on one end of the spectrum. On the other end we need a logging level whose messages would be so verbose and so often called that we would almost never need a finer level. DEBUG is too general purpose for that. I disagree, think DEBUG is fine for the other end of the spectrum, and wouldn't use something lower than that. However, if there's really an overwhelming majority of people who disagree, then by definition I'm in the minority and these levels should be added ;) But I'm yet to be convinced this is the case...

RE: Plans for supporting a build in level of trace
Howdy, To separate concerns. Because trace info is a specific level, more minutia than debug info. That's your use-case, not mine. Both are debug for me. I never want one without the other. theValue=... is useless if I don't know what method it's in. Having TRACE in Log4j means: 1) No requirement to extend Log4j on each project; it is an intrinsic logging type. No such requirement exists in any organization I've ever worked, people use debug-level statement without extending log4j. People who use JDK 1.4 don't use the trace level. But that's only my experience, which is no less or more meaningful than anyone else's. 3) People want it, it does not break backwards compatibility, and it adds one more level of logging clarity. Convince me that a majority wants it. How come it doesn't come up more often on the log4j user list? 4) It matches levels with commons-logging. Why does it have trace? ;-) SOLELY because JDK 1.4 has it and commons-logging was designed to map to both log4j and commons-logging (among other logging kits). As Paul said, this is an eternal debate, kind of like whether to include version numbers of a release in the jar file name.

RE: Plans for supporting a build in level of trace
Howdy, I agree that this debate will carry on forever, because we all work differently. I believe having one trace level is good compromise. The way I work is to put debug statements into the code to decipher what is happening in the program flow, but I would love to have a trace level to print out parameter values or variable values. The debug level gets extremely verbose when logging out array values etc and all you are interested in is program flow. Interesting that the above is exactly the opposite of what Jeff's use-case is: trace for entering/exiting methods, debug for variable values ;) Yoav This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

RE: Plans for supporting a build in level of trace
Howdy, It does not really matter what TRACE level gets used for. Each development team / organization will have their interpretation of it depending on how they intend to use the information logged at both levels. I agree, it doesn't matter what it's used for, only if it's used at all. More importantly - having a level more verbose than DEBUG is very handy. We Very handy for you. 1. TRACE level 2. An extension of DailyRollingFileAppender that also uses filesize as a rolling criterion 3. MBeans support Would you consider 2 and 3 as important to the core of log4j as 1 above? Clearly you think 1 belongs in the native log4j core. The point I'm making is not as much about the TRACE level per se. I know some people want it and use it. It's about adding a feature to the core of a product where: - It's not clear how useful the feature is, and - It's not clear what the backwards compatibility implications are, especially for organizations that already have their own custom TRACE level (or other levels that go between DEBUG and OFF). Hypothetically speaking, let's say there was a log4j sandbox jar with a Level class replacement that includes a TRACE (and maybe FINE, FINER, FINEST, REALLY_FINEST, ABSOLUTELY_FINEST, IT_CANT_GET_ANY_FINER, etc ;) -- just kidding) level, would that be useful for people?

Interesting clover-related issue
Howdy, I use log4j as you all know ;) To observe good performance practices, I surround my logger.debug statements in if(logger.isDebugEnabled()) blocks. All works well. I have many JUnit tests, and integrated unit test coverage reporting with Clover (http://www.thecortex.net/clover/). Let's say I'm testing class SomeObject, and the JUnit class is SomeObjectTester. In my tests, I want to exercise the logger.debug blocks as well for maximum coverage, so prior to starting the tests I do the following in the SomeObjectTester class: Logger someObjectLogger = Logger.getLogger(SomeObject.class.getName()); someObjectLogger.setLevel(Level.DEBUG); And that works fine, no problems, the debug blocks are exercised. However, because all the if(logger.isDebugEnabled()) checks are true, never false, I can never get 100% code coverage. So one solution would be to run all the tests twice, once with debug-level logging enabled for the tested class, and once with a higher level threshold. But that seems annoying, slow, not elegant. Has anyone run into this before, come up or can think of a different solution to getting 100% code coverage for this coding pattern?

RE: Advice needed
Howdy, 1 - Is there an upper file limit? Only what's imposed by your filesystem. 2GB by default on many filesystems I believe. 2 - As I understand it Log4j *will not* shut down our app if it has a problem. You understand correctly. 3 - Is it bad practice to allow log files to grow that big? I would say yes, unless you have (and want to use) some sort of extracting tool. When they're that big they're too verbose and long for a human to analyze in a reasonable amount of time. We will probably keep our logging quite verbose for the first while when we go live. Why? A big part of log4j is the ability to turn verbosity on/off at runtime. I would start with it off and use a mechanism like the log4j sandbox configuration servlet to turn on selected classes/packages at runtime in production as the need arises. Or even configureAndWatch if you're not in a webapp environment. Should be rolling on file size instead of date? Either policy can make sense, depending on your app. As I believe what I said above, our log files for a given day tend to be quite small ( 10K) and I roll on date, not size.

RE: Log4j best practices
Howdy, I think that's a better practice because I don't like mixing configuration files and classes. Other people do like this approach and the auto-initialization you get with it.

RE: [Fwd: tomcat 4.1.27 log4j 1.2.8 struts 1.1 = crash on logger.debug()]
Howdy, to my ae.jar file, even though I have explicitly told it not to. I am sorry that I didn't unzip my jar files earlier, but I figured checking JBuilders jar gui screen was enough. So Chalk one up for open source! It was a JBuilder bug. And chalk another bug to overcomplicated, overpriced, over-abstract IDEs. But I'm not going to get stated on this topic ;) Why are the JBoss tomcat jars in Tomcat? They're there in the JBoss distribution of tomcat only, not in the standalone tomcat distribution. They're there to support some custom embedded tomcat functionality JBoss does. I am instantiating my ejb session bean as a local class in my web app so that I don't have to set up a jboss container for this development session. The idea here is that I can decide at deployment time how many tiers that my application should use. Basically, forget about it with current versions of tomcat and JBoss. Between the classloading and JNDI implementations alone, you're screwed ;) If you want JBoss-Tomcat, use the bundle. If you want tomcat standalone, use its standalone distribution that doesn't have any tomcat jars. This architecture selection carries significant weight and to try to do it at runtime is difficult at best. That said, if you come up with a working solution, I for one would be interested in the details ;) Yoav Shapira This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

RE: No of Logger instances
Howdy,
It won't be an issue. We have systems with tens of thousands of classes
loaded at runtime (and many of them in the working set of the app). We
use the logger name = fully-qualified class name convention, and it
works perfectly for us with no performance degradation.
What does make a big difference, since you seem to care about this, is
using if(logger.isDebugEnabled()) { ... } around logger.debug
statements.

RE: Can I create empty log files (without logging events)?
Howdy, It's not a stupid question, but (without knowing better) it seems like a stupid requirement. Since you're already using a custom appender, why not modify it to touch i.e. create the log file in its activateOptions method? Better yet, add a configurable option to create an empty file. It may be more of a java.io issue then (maybe open the file, write an empty string to it, flush the writer?).

Hi! First, let me say that I'm very, very new to log4j and all, so the following question(s) might sound stupid to you - in that case please forgive me. The challange that I'm facing right now it this: I'll have to make some changes to an application I know virtually nothing about - someone at my company thought this would be a good idea... That appliation is using log4j and a ConfigurableDailyRollingFileAppender which is derived from DailyRollingFileAppender. Now, this works in general... BUT... now they want me to change the logging behavior in a way that the logging system generates log files even when there are NO logging events (when the system wasn't doing anything). These files will of course be empty (in a shell I would do a touch and that's it) and - in other words - completely useless. That's what I told them also but they still want to have it. Is there any way to get log4j to generate empty log files even without any logging events? By the way, these log files have to be generated every two minutes - even if they are empty... Any ideas? I mean I could also set up a cron job that generates empty files every two minutes but I doubt that I'll get this in sync with log4j. Thank you very much in advance for answering my stupid question.

Do you have a appenders named R and D defined in the file?
Also, you know you don't have to assign appenders to all the packages, only to the

RE: how do I log an exception stacktrace
Howdy,
try {
String a = null;
System.out.println(a.length());
} catch (Exception e) {
logger.error(Error printing string: , e);
}
Note the comma, i.e. the error(Object, Throwable) version of the API.
All the levels (logger.info(...), logger.warn(...), etc) have a version
of their signature with a Throwable argument.

RE: Log file location
Howdy,
Look in the JBoss log for errors initializing log4j. Turn
-Dlog4j.debug=true to see log4j internal debugging output. Try
different paths for your File argument, e.g. d:\jboss\errors.log or
d://jboss/errors.log.

Subject: Log file location
Hi,
I am unable to set log file location. I searched the forum for old
messages
and found some. I tried the way it was mentioned in those messages, but
still my problem is not solved.
My log4j.properties file is as follows:
log4j.rootCategory=WARN, dest1, R
log4j.appender.dest1=org.apache.log4j.ConsoleAppender
log4j.appender.dest1.layout=org.apache.log4j.PatternLayout
log4j.appender.dest1.layout.ConversionPattern=%-5p: %m%n
appender writes to a file
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%-5p: %m%n
log4j.appender.R.File=d:/jboss/errors.log
I packaged by application as .ear and deployed it on JBoss running on
Win
2000.
When I run the application, I can see the log messages on JBoss
console,
but these messages are not getting stored in the file I've specified
(d:/jboss/errors.log).
What could be the problem? In fact, initially I tried
${jboss.home}/errors.log, but it didn't work. So I thought of hard
coding
the file location and tried it out. Still the same problem.
Can someone please suggest a solution?
Thanks

Hello,
This is a question about a post from several weeks ago. I
wasn't
ready to try it at the time, but I saved it because I knew I'd need it
later on ... :)
When I tried to use filtering as described in the original
post
(actually, I created a filterset inside the copy tag), it works fine
except that on Windows 2K it contains back-slashes(\) from my
$CATALINA_HOME env variable and forward-slashes(/) from the subpath
info
inside of Ant. Then, when log4j gets it, the backslashes are
effectively
ignored (probably interpreted as escaping the next character) so
log4j
complains that no such directory exists.
Is there a way to get log4j to accept either path-separator
character, or alternately is anyone aware of an Ant function to force
filtering to use the platform-dependent path separator when replacing
text ??
My Ant build.xml looks basically like this:
property name=installdir
value=${env.CATALINA_HOME}/webapps/MYAPP/
target ...
copy todir=${build}/WEB_INF/classes
file=${basedir}/config/log4j.xml
filterset
filter type=INSTALLDIR value=${installdir/WEB_INF/
/filterset
/copy
/target
And my log4j.xml looks roughly like this:
appender name=XYZ
class=... RollingFileApppender
param name=file value=@INSTALLDIR@/myapp.log/
.
/appender
In the destination log4j.xml file, the value for the appender's file
param is C:\Java\tomcat/webapps/MYAPP/WEB_INF/myapp.log. Any
thoughts

Howdy,
This is a common problem, and you have several options.
The logging works fine. The problem is specifying the location of
the
log
file.
I use log4j.xml to configure log4j. In there I have to specify the
location
of the
log file as absolute path. This creates a problem because we have to
edit
You don't have to specify the path as absolute: it can be relative (to
the working directory), and it can contain environment variables.
log4j.xml
during each deployment of our application to edit the location of
the
log
file.
Another option is to automate this by copying the log4j.xml file with
filtering=true in Ant. In log4j.xml you'd have a token value for
the
log file path, e.g. @logFilePath@, and when deploying you'd have Ant
replace this value with a value coming from an Ant property.
I attempted to solve the problem by adding the following code in a
utility
class
rootLogger = Logger.getRootLogger();
FileAppender fp = (FileAppender)
rootLogger.getAppender(LOGFILE);
This is yet another option, the pure programmatic way. I find this
useful some time, but cleaner if you create the appender
programmatically as well, i.e.
Layout l = ...
String logFilePath =
Appender app = new FileAppder(l, logFilePath);
Logger.getRootLogger().addAppender(app)

Ant can handle either way, forward or back, as long as it's consistent.
The problem arises when a single string uses mixed slashes. Ant's
FixCRLF task works in this area and might be useful here.

Thanks for the suggestion, but that doesn't work either.
So now I have:
property name=installdir

filter token=INSTALLDIR
value=${installdir/WEB_INF/
copy todir=${build}/WEB_INF/classes

/target
And the generated log4j.xml file has the same mixed / \
values.
Beyond that, I tried to manually change all the '/' to '\' in
the
generated log4j.xml file and when I ran it, it put the file under
tomcat/bin and its name was the concatenation of all the path elements.
I
then tried to escape the backslash and that worked fine! This would
sound like a problem with the xml parser log4j is using when it is
parsing
the value param and handing it to log4j.
Oddly enough, when I changed all the backslash's to
forward-slash's, that worked too. I thought on a Windoze box, Java
used
the system-dependent filenaming conventions when creating a
FileOutputStream (which is all that log4j does with the filename)?
So are you doing this currently on a windoze or *nix box? I
can
see how it would work in a non-M$ environment. Thoughts?

Yaov,
Agg why didn't I check the book before posting
that!! On page 101 of Ceki's book, the File option has a full
description
associated with it, including the note about having to escape the '\'
on
the windoze platform, and also about being able to simply use the '/'
instead. Having said that, it might be useful to have that note in the
javadocs too. :)
So basically all I need to do is simply convert my
CATALINA_HOME
value to use '/'. Sorry for wasting everyone's time.
BTW, I did look at the fixCRLF task, but that operates on the
entire file, and I wasn't sure that there wouldn't be any '\'
characters
somewhere else in my log4j.xml file. So, the final solution that I
came up
with is as follows, and this should work on both Windoze *nix.
property name=installdir
value=${env.CATALINA_HOME}/webapps/MYAPP/
target ...
pathconvert dirsep=/ property=logfile

path=${installdir}/WEB-INF/${ant.project.name}.log/
/pathconvert
filter token=LOGFILE value=${logfile}/

Consider putting this code in a ServletContextListener's

My questions are:

Instead of doing this whole property replacement scheme, why not just
specify a system-property based file name in your log4j configuration
file, e.g.
log4j.MyAppender.File=${CATALINA_HOME}/logs/myLog.txt

RE: discreet logging types - revisited
Howdy, I'm a fan of the Level system and its relationship, so no I'm not interested in your suggested mods, but I wanted to throw out an idea or two for you that might reduce the need for coding: - Can you use separate logger repositories as your types ? - Can you use a Filter attached to the root logger that matches based on type as an MDC attribute of the logging event? Yoav Shapira Millennium ChemInformatics -Original Message- From: Larry Young [mailto:[EMAIL PROTECTED] Sent: Thursday, August 14, 2003 3:10 PM To: [EMAIL PROTECTED] Subject: discreet logging types - revisited Hi all, Well, I'm still looking at how to use discreet logging types instead of the Level to control what messages are enabled. The difficulty resides in the need to enable/disable certain log types by package/class name. BTW, I posted my original message on 7/30/03 if you are interested. Basically, the way I've always built logging systems is by defining a set of discreet types to be used by the developers, and then allowed those types to be enabled/disabled individually. Unfortunately the level concept is fairly hard-wired into log4j. I say unfortunately not because levels are bad, but because there is no way to expand or get-around them with an alternate approach. Actually, levels can be viewed as a set of discreet types with an implicit ordering/relationship between them, but in log4j, there is no way to control the relationship test. Before I go on too much (which I do!), is there anyone else who is interested in discussing the idea of replacing the level with discreet types in the log4j package?? Basically I'm at a point where I need to make some decisions regarding how to proceed. If other members are interested in pursuing this idea, then I'll explore the idea of modifying the Logger classes (et. al.) to replace the level with types, with the intention of folding those changes back into the product. But if no one is interested, I'll just make some small mods to Logger for my own purposes and handle it as a one-off type situation. In either case, I intend to move forward with log4j! It has many features which I'm planning to use in the future (like that IMAppender being discussed!!). Mostly its a matter of whether I do a complete implementation to replace levels, or just a quick fix to solve my problems. Thoughts, comments ???

RE: Separate configs for different webapps
Howdy, Thanks Jake for adding the links: your solution will work, I've tried it myself in the past. That said, I fully agree with Senor Coast's advice to not share jars across webapps, even if they're exactly the same. Keep all the jars for your webapp, including common ones, in WEB-INF/lib. Or just deploy as one WAR file. Webapps are supposed to be self-contained, and you will save yourself many configuration and debugging hassles if you stick to this principle.

RE: Creating log files relative to the web applications root directory?
Howdy, U, so basically then it is not possible to define a directory path in the log4j.xml properties file so that log files are placed relative to the web apps root directory? Or for that matter relative to any known anchor point like the server root directory? A problem we have is that we deploy .war files by sending the package to the server gods who then drop it into the webapps directory. Alas we don't This is a typical scenario. As Senor Ebersole suggested, you would reach agreement with the server admins on a particular directory or other repository where you can log. You would then use the System property or JNDI approach I illustrated in previous messages in this thread, except they set the property (or setup server.xml for JNDI), not you. Your app should complain and/or use a default setup (BasicConfigurator.configure() for example) if this property is not found. based machine and the production servers are hosted on a flavor of Unix. Hard coding a directory path like C:\..\ may work when doing the dev work under Windows but just don't kind of cut it on a Unix file system when it comes time to deployment. Even if you didn't have a mixed system deployment, hard-coding is a bad idea ;) I would throw out one other type of option for this case: if you control some servers, but not the ones you deploy to, you could have your apps send logging messages to the servers you control, e.g. via a SocketAppender or JMSAppender, or JDBCAppender even. Then you can figure out how to persist the messages yourself.

RE: log4j: dump wrap-around buffer of all log messages
Howdy, I don't see your point. If you put the logged messages to a circular buffer that holds say 16k messages at a time, then you won't have high memory usage just 16k*size of a logged message. Of course if your code if full of debug logging, then the program will be slow, but on the other hand will give you very valuable feedback in case of an exception/error. 16k times the size of a logged message can be large, first of all. Secondly, that amount might be multiplied many times by having a separate buffer for each logger. Secondly, I like to be able to make the tradeoff of performance versus information myself, i.e. via configuration and reconfiguration at runtime. I will not accept a system that always keeps an extra 16k messages in case there's an error. I'm not saying this feature is a completely bad idea. It can be useful in certain cases. However: - log4j is in a sweet spot performance-wise, and care should be taken to maintain that. - When someone is considering moving to log4j from another package, complaining of the other package's performance, and then asks to add a feature that seems like a performance hog to log4j, that's a red flag for me. I will be glad to be convinced otherwise by a benchmark, however...

Log4j's big advantage is its performance, but still I'm missing a feature that is present in the Java Trace package: the ability to dump a wrap-around buffer of, let's say, the last 500 log messages in the log file. The wrap-around buffer (think of it as an array of let's say 500 log messages) contains at any moment, the last 500 log messages. The idea is that the logger has 2 log levels: one which determines what level is present in the log file (or std out or whatever), another which determines at what level the internal wrap-around buffer is filled with messages. This way, it is possible to let your application log at level INFO, while the internal buffer keeps all messages of level DEBUG or higher. When an exception is thrown, the user should have the ability to request a dump of the buffer, such that the more detailed DEBUG messages are also present in the log file to make debugging more easy.

RE: Newbie how to place logfile under tomcat logs
Howdy,
Thanks, thats a help but because of the setup of our application, I
cant
use the first two options, and I'd rather not define another properties
file just to store ${CATALINA_HOME}/logs/logs.txt. Is there any way I
can
do it programatically? What are the other options?
No. It would be against the spirit, if not the letter, or the servlet
specification for a servlet to be able to find out such details about
its container. Even the approaches I showed before weren't that
portable. This is like those perennial how can I find out what port
the server is running on in my servlet's init() method? (You can't with
certainty/portability).
Other options include adding a JNDI entry for your log file path into
tomcat's server.xml and then doing a JNDI lookup in your servlet's init
method, or mangling your log4j configuration together with tomcat's
commons-logging configuration. The latter is just cruising for a
bruising, and the former is too container-specific (requires modifying
server.xml) for my preferences, so I didn't include them before.
Typically the Ant option is the one I like best, but I guess you don't
use Any to deploy/package your application?

I have the following in a log4j.xml file located in web-inf/classes
with
the
log4j jar in the web-inf/lib directory. Logging seems to be fine
except
the
rascal.log file is being created in the Tomcat application directory
under
C:\Program Files\ and not in the C:\Tomcat 4.1\webapps\... Directory
tree.
I'd prefer to have the log files in something like
../webapps/application/logs/logfilename. Is this possible?
BTW, took a while to find the rascal.log file!!!

RE: calling DOMConfigurator.configureAndWatch() 2 times
Howdy, What should happen if the configureAndWatch() function is called twice? Are the previous settings erased? Are they accumulated ? It wouldn't be that hard to simply test this and see what happens ;) But looking at the code, you see: - configureAndWatch always creates a new XMLWatchdog, so you will have two XMLWatchdogs watching over the file. - Each XMLWatchdog would call DOMConfigurator#doConfigure(filename, repository) when the file changes, so this method will get called twice. So this is extra overhead that should be avoided if possible. - The configuration file will get parsed again with a new parser - Parsing will replace where found and add where not found. So if there's already a logger for class, for example, it will be retrieved if it exists and reconfigured, or a new one will be created if one doesn't exist. You can walk through the rest of DOMConfigurator if you feel like it ;) This is one issue where the test is easy so I wouldn't even spend time looking at the code ;) Yoav Shapira This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

RE: log4j: dump wrap-around buffer of all log messages
Howdy, I would really want this sort of feature benchmarked for memory use ;) Perhaps this is one of the reasons log4j has better performance than your current java trace kit ;) Yoav Shapira Millennium ChemInformatics -Original Message- From: Ceki Gülcü [mailto:[EMAIL PROTECTED] Sent: Monday, August 11, 2003 9:24 AM To: Log4J Users List Subject: Re: log4j: dump wrap-around buffer of all log messages Yes, this is certainly possible. The SMTPAppender works in a similar fashion. At 03:09 PM 8/11/2003 +0200, you wrote: Dear log4j users, Currently I'm evaluating log4j 1.2.8 to replace an other Java Trace package (see http://visibleworkings.com/trace/) in our applications. Log4j's big advantage is its performance, but still I'm missing a feature that is present in the Java Trace package: the ability to dump a wrap-around buffer of, let's say, the last 500 log messages in the log file. The wrap-around buffer (think of it as an array of let's say 500 log messages) contains at any moment, the last 500 log messages. The idea is that the logger has 2 log levels: one which determines what level is present in the log file (or std out or whatever), another which determines at what level the internal wrap-around buffer is filled with messages. This way, it is possible to let your application log at level INFO, while the internal buffer keeps all messages of level DEBUG or higher. When an exception is thrown, the user should have the ability to request a dump of the buffer, such that the more detailed DEBUG messages are also present in the log file to make debugging more easy. Is this possible in log4j? If not, has anyone a workaround for this or should I ask for a feature request?

RE: Newbie how to place logfile under tomcat logs
Howdy,
this may be more a tomcat question so appologies if it is off-topic.
I want to plcae the log file under %TOMCAT_HOME%\logs (where all the
tomcat logs go).
Reading the archives of this list or the tomcat-user list would've
revealed answers, as this is a fairly common question.
I have defined in web.xml:
servlet
servlet-nameMyServlet/servlet-name
servlet-classfoo.bar.MyServlet/servlet-class
init-param
param-namelogfile/param-name
param-valuelogs.txt/param-value
/init-param
/servlet
and in the servlet:
String logFile = getInitParameter(logfile);
appender = new FileAppender(layout, logFile);
You have a number of options, including:
- Setting param-value in web.xml to be an ant token, e.g.
param-value@logFilePath@/param-value
and have Ant fill in this token from whatever properly you want, e.g.
$CATALINA_HOME/logs/logs.txt, when it's deploying web.xml.
- Adding -DCATALINA_HOME=$CATALINA_HOME to your JAVA_OPTS in
$CATALINA_HOME/bin/catalina.sh so that you can get Catalina home via
System.getProperty(), then do
String logFile = System.getProperty(CATALINA_HOME) + /logs/ +
getInitParameter(logFile);
- Using a log4j configuration file, rather than programmatic
configuration, and having something like
log4j.myAppender=org.apache.log4j.FileAppender
log4j.myAppneder.File=${CATALINA_HOME}/logs/logs.txt
...
There are other options as well.
