Re: Not able to DELETE Log Files

Just create one appender per level and use a LevelFilter to get only the correct level. You may find that doing something slightly different is more useful.

Re: JUnit testing of output logged with log4j?
One option would be to using a test log4j.xml file that has appender
filters that filter out expected error messages. Maintaining that
might not be easy.
On 6/23/07, Bob Jacobsen [EMAIL PROTECTED] wrote:
I've got a bunch of code that uses log4j for logging, and a large
number of unit tests done with JUnit.
As is the nature of these tests, they test a lot of error conditions,
which results in lots of error and warning messages logged when
running the tests. Up until now, we just ignored those: If the
tests passed, nobody looked at the test output. If the tests failed,
then we started looking at the output for abnormal errors, which is
really a mess.
My co-developers and I would like to clean this whole situation up,
so that the tests run with no error or warning messages appearing in
the output log. But we still want to _test_ the conditions that are
errors, and in the code as it exists will throw those messages.
And we still want to see if _other_ error and warning messages start
appearing when the tests are run.
Anybody know how to Do This Right?
So far, we've got a couple suggestions:
1) Go through and find all the places where the error messages are
logged, and make then log through a service routine which can be
over-ridden. E.g.
class Mine {
void doSomething() {
...
if (bad) log.error(Oops);
}
}
becomes
class Mine {
void doSomething() {
...
if (bad) report(Oops);
}
void report(String msg) {
log.error(msg);
}
}
Then we can test it with
new Mine(){
void report(String msg) {
if (!msg.equals(Oops))
// assert error
}
}
The subclassing lets us intercept the error _before_ it gets to
log4j, and test it manually. But there's a _huge_ amount of this. It
seems a complete pain to do all this, and since we'd be putting in a
cover layer in front of log4j in each class, it seems far from a
best practice.
2) Instead of suppressing the good messages, learn to ignore them.
To do this, we'd just take a log from normal tests, and built into
our testing that we diff the current output with the normal log.
New or missing lines would be visible to the author; the same old
stuff would pass through the diff.
Of course, this is a maintenance nightmare. As code changes, we'd
have to keep the master error log synchronized, but it would be
easy for somebody to pass a Really Bad Thing as a new normal error.
This is currently the most popular choice, mostly because it doesn't
need to rework the existing code, but I really don't like it.
3) Do something via log4j itself.
I'm not even sure what I'm asking here, but can we somehow
programmatically access a stream of log4j log entries, and manipulate
it?
What I'm imagining is a test like this:
a) Push all existing stuff in log to whatever outputs are configured.
b) Temporarily stop output of log entries
c) run test
d) Check through log entries accumulated since (b), which come from
the test, and remove the ones that are expected (optionally, tell
JUnit to fail if something is missing)
e) Allow all other log entries to continue to their configured outputs
If there was some way to do this, we could have unexpected messages
still go to the usual places, as configured, but remove expected
messages from the log stream.
Is there a way to do this?
Or is there a better solution to the whole need?
Thanks in advance.

Re: Urgent Please--How to create different log files with different property files in same webapplication
Can you better explain the relationship between abc and xyz? It
sounds like xyz uses abc as a library and that abc also runs by
itself.
Repository selectors might help.

(3) Is there a way I set the DEBUG warning to just log to the Console and the
LOG warning to just log to specific files (which I specify)?
(4) What if I wanted two separate log files generated for the file appender?
(e.g. one being for cars.log and another one being planes.log)
(5) Do I have to create a different init servlet and different properties file?
Happy programming,

Re: Third Party Appenders
Depending on they number of distinct messages that interests, you could have separate appenders for each message (using filters). Depending on the volume you may only want to roll weekly or monthly so that tail would work better. Or you could just have a program that checks the special appenders for an increase in size.

With the additivity of the org.apache.commons.httpclient logger set to

org.apache.commons.httpclient will also be processed by any explicitly

To change this behavior, just set the additivity on the

Hi James,
thanks for your fast answer, but this only corrected some error
messages from HTTPClient (didn't know that the order of entries plays a
role). The HTTP output appears further in my logfile. Perhaps I will
try to put this question to httpclient mailing list.

give it a try.
However, after reading a couple of the tutorials and the online manual
I find myself running into some trouble. I'm trying to use a logger
with a FileAppender, but when I execute my program no messages are
ever written to the text file. I know the method with the logging code
is being executed because it appears in a stack trace from an
exception that is generated shortly after the logging code.
In my logging code I create a Logger, create a Layout, and then create
a FileAppender passing a simple layout, the name of a text file, and a
boolean value of true. I then associate the FileAppender with the
Logger and write two messages.
When I open the text file identified in my code it is empty.
What step am I missing? (I create a text file with the correct name
before executing the logging code.)
Thanks in advance for the help.
Scott Huey,
P.S. - I'm using the latest stable release of log4j, Eclipse 3.2.1 and

Logger.getLogger(com.vividsolutions.jump.workbench.ui.LayerViewPanel.class);
SimpleLayout layout = new SimpleLayout();
FileAppender appender = null;

Re: AsyncAppender Issue
How are you configuring AsyncAppender. I think it has an option that throws away logs when the buffer is full. On 4/10/07, Luedecke, Michael J [EMAIL PROTECTED] wrote: I'm losing logs when I use the AsyncAppender for some reason. This loss of logs occurs whether I'm using a custom appender or out-of-the-box appender (i.e. FileAppender). I have not noticed this problem when I send a string in the log method call. It only seems to happen when I pass an object in the log method call. The object I'm sending in the log is not large or complex. It is a HashMap collection containing only 5 or 6 entries. The logs that get created successfully varies. Sometimes I get all of the logs I'm expecting, but, most of the time I don't. If I use the appenders without the AsyncAppender I'm consistently getting all of the expected logs. I'm not creating a large number of logs (my test case only creates 3 logs). Nevertheless, I have tried to change all of the options used by the AsyncAppender just in case, but it has not resolved anything. Other characteristics of my environment: * Using log4j 1.2.14 * Using JDK 1.4.2_14 * OS is Windows XP Has anyone else experienced this type of behavior with the AsyncAppender?

Re: Conditionaly sending email with Log4j
One option would be to have separate loggers per form and then only attach the appender to the desired logggers. Note that SMTPAppender only sends email when it encounters and error (or higher) level logger..

When an exception occurs, the app needs to send an email to an admin depending on which form threw the exception. I already have lo4j in place with an SMTP appender configured. What I cannot figure out is, how do I conditionaly send emails? I could setup multiple SMTP appenders, but how would log4j know which appender to use when a particular form throws an exception? The best solution I can come up with, is to subclass SMTPAppender and override sendBuffer(). When sendBuffer is called, the appender name would be compared to a value stored in the MDC. If a match is found then super.sendBuffer would be called. Cany anyone think of a better solution? Thanks. - Tyson -- James Staufferhttp://www.geocities.com/stauffer_james/ Are you good?

Re: Custom appender question about getRenderedMessage()

Re: Enh rqst: a variation on DailyRollingFileAppender
I wrote an appender that always uses the formatted name. http://stauffer.james.googlepages.com/DateFormatFileAppender.java On 3/23/07, Andrew Marlow [EMAIL PROTECTED] wrote: guys, I am using DailyRollingFileAppender to have an AM and PM log for each day. This isn't quite what I want but is close enough for now. What I would really like is an appender that writes directly to the target file, rather than it writing it to a different file and rolling that file over at a certain time. It's the rolling over that I don't like. I have had some weird problems where log4j sometimes complains that it cannot do the rollover at startup. Here is an example of how a logger worked that I was using before I started using log4j. The logfile name was of the form prefixmmdd-w.txt where w is a watch number. The day is divided into 6 watches of 4 hours each, i.e. -0400, 0400-0800, 0800-1200, 1200-1600, 1600-2000 and 2000-2400. Each time a call is made to the logger it ensures that it is writing to the correct logfile for the current watch. If the file exists the record is appended, if the file does not exist it is created. The advantage of this system is that you always know which logfile to look at and you dont need to worry about rollover. Is there any chance of log4j being able to offer this facility please?

Re: Logging Domains
What if you had loggers named normally. Then to create your view, create a separate appender and attach it to the loggers for that view. i.e. Attach a DAOAppender to all DAO loggers and then you can change the logging for that view by setting the threshold on DAOAppender. That would tend to put view-specific output in different files but it wouldn't have to be that way.

My expectation in using log4j was that a call to logger.isXXXEnabled()
would return true only in the case that a call to logger.XXX(some
message) would result in the message being written to some appender.
However, it appears that the existence of an appender has no bearing the
Enabled call.
For example, I have this simple configuration:
?xml version=1.0 encoding=UTF-8 ?
!DOCTYPE log4j:configuration SYSTEM log4j.dtd
log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'
appender name=STDOUT class=org.apache.log4j.ConsoleAppender
param name=Threshold value=debug/
layout class=org.apache.log4j.PatternLayout
param name=ConversionPattern value=%-4r [%t] %-5p %c %x - %m%n/
/layout
/appender
root
level value =info/
appender-ref ref=STDOUT/
/root
/log4j:configuration
Using this configuration, and this program (based on log4j's examples):
package chapter3;
import org.apache.log4j.Logger;
import org.apache.log4j.xml.DOMConfigurator;
public class BugApp3 {
//final static Logger logger = Logger.getLogger(BugApp3.class);
final static Logger logger = Logger.getLogger(chapter3.BugApp3);
public static void main(String[] args) {
DOMConfigurator.configure(args[0]);
logger.info(Entering application.);
//debug is not enabled
logger.debug(Debug is enabled.);
if (logger.isDebugEnabled()) {
logger.info(isDebugEnabled() returns true!);
}
logger.info(Exiting application.);
}
}
I see the following output:
% java chapter3.BugApp3 bug0.xml
0[main] INFO chapter3.BugApp3 - Entering application.
2[main] INFO chapter3.BugApp3 - isDebugEnabled() returns true!
3[main] INFO chapter3.BugApp3 - Exiting application.
However, if I set the root level to debug instead, then I get this
output instead:
% java chapter3.BugApp3 bug0.xml
1[main] INFO chapter3.BugApp3 - Entering application.
3[main] INFO chapter3.BugApp3 - Exiting application.
Since the goal of an isXXXEnabled() statement is to avoid doing
unnecessary work in the case where it will not result in actual debug
output, it seems unfortunate that it does not take into account the
existence of an appender.
Is this behavior intentional?

Re: DailyRollingFileAppender help needed please
That log4j output is telling you that maxLogs isn't a valid property of DailyRollingFileAppender. DailyRollingFileAppender only uses the date pattern when it needs to roll. The current file is always named exactly the value of the File property. From javadocs: For example, if the File option is set to /foo/bar.log and the DatePattern set to '.'-MM-dd, on 2001-02-16 at midnight, the logging file /foo/bar.log will be copied to /foo/bar.log.2001-02-16 and logging for 2001-02-17 will continue in /foo/bar.log until it rolls over the next day.

Re: Multiple logging files
3. Both the system property and any needed directories need to be set
before log4j is configured. I created an appender that can create
directories as needed and it is at
http://stauffer.james.googlepages.com/DateFormatFileAppender.java
4. In your code you don't refer to a special appender, you refer to
special loggers.
i.e
Logger logger = Logger.getLogger(getClass().getName());
Logger specialLogger = Logger.getLogger(special. + getClass().getName());
logger name=special
level value=info/
appender-ref ref=specialAppender /
/logger
root
priority value =info /

But what do I need to specify in the XML file ?
* Is it correct what I did in the special appender ? I specified the

The easiest way to configure it only once is to put the config file in the classpath and allow it to be automatically configured. An alternative is to call doconfigure in static code that is only called once. On 2/27/07, Surya Poola [EMAIL PROTECTED] wrote: Iam sure the code is only executed once, why because without specifying any configurator and placing log4j.xml in classes folder of the web application, everything works fine.But when i specify configurator and remove the log4j.xml from classes folder and place log4j.xml in different location and refer the log4j.xml by configurator then iam facing this problem. Iam running my program through tomcat,and calling my program in doget() method of servlets like: logger=Logger.getLogger(this.getClass().getName()); JoranConfigurator jc = new JoranConfigurator(); jc.doConfigure(C:\jakarta-tomcat-4.1.30\webapps\log4j.xml,LogManager.getLoggerRepository()) logger.info(test log ); Regards Rohan James Stauffer [EMAIL PROTECTED] wrote: Are you sure that code is only executed once per program run?

Re: Changing loglevel at runtime (systemwide)
Would it work to have two output files(or sets of files) -- one at normal level and one at debug level? Then if you don't need the debug output just delete the debug logs. On 1/25/07, Detering Dirk [EMAIL PROTECTED] wrote: Hello all, I subscribed to this list to get some help regarding a problem with conditional level switching we encountered in our development team. Let me first explain what we do and why. Background: Application: A code generator, doing two steps: Model validation and code generation for each class in the model (more or less). The generator is developed in our team but used in many other application development teams. Problem: The validation may be incomplete, causing the generator to throw runtime exceptions at unexpected locations during the generation step. In this case, the stack trace isn't very helpful, as it documents somehow _where_ the problem occurred, but not clearly _why_ (means: which model element caused the problem). This is partly due to Velocity. Current solution: The time consuming solution is to reconfigure the log settings to get DEBUG infos from different generator classes during runtime, and restart the whole generation. Drawback: * A generator developer has to be involved to analyse the stack and do the right debug configurations * The complete generator run has to be repeated * When switching a Logger to DEBUG, it _always_ logs what it does, not only for the problematic part/element of the input model. So the output has to be filtered to separate the relevant information from noise. Perhaps better concept: Our intention was to catch the thrown exceptions at the location where the model is iterated and the generation triggered for each element, and to retry the generation after setting the whole system into DEBUG mode - and setting it back to its former state after catching the exception again(!) Advantage: * We would get a verbose track of what the system does, but only with the critical model element, not with all others. * The debug info would automatically be created during the first run by the app. developer. So no need to completely rerun, no need to configure, no need to involve our dev. team at this stage. Here's our log4j problem why I post now: As the basic configuration is just complex, involving many loggers and appenders, we can't only set one or two logger into debug mode. Settings at some upper level in the hierarchy don't help, as some loggers much deeper are configured explicitly and keep their own setting. Reconfiguring with another property set would presumably cause rolling file appenders to create a new generation after restoring the configuration (?). So we tried to write a RepositorySelector do retrieve another (much simpler) hierarchy in case the system goes into debug. But this does not work either, as the Loggers are instanciated and kept in static variables of classes (as recommended) which are put into caches _before_ the system switches to DEBUG, i.e.: The second hierarchy is mostly never queried, each instance knows its logger. So, what would be the right way to achieve a systemwide switch to debug level and a reset to normal configuration afterwards?

I have tried everything. I edited the mvn script under the install directory
to include the following:
exec $JAVACMD \
$MAVEN_OPTS \
-classpath ${M2_HOME}/core/boot/classworlds-*.jar \
-Dclassworlds.conf=${M2_HOME}/bin/m2.conf \
-Dmaven.home=${M2_HOME} \
-Dmaven.junit.sysproperties=log4j.configuration \
-Dlog4j.configuration=file:C:\tmp\log4j.xml \
${CLASSWORLDS_LAUNCHER} $QUOTED_ARGS
this does not work (have tried with and without file:.
---
I have included a something similiar on the mvn command line:
mvn -Dlog4j.configuration=c:\tmp\log4j.xml test
this does not work (have included =file:c:\tmp... as well
---
I have also tried setting properties in the pom.xml like so:
plugin
groupIdorg.apache.maven.plugins/groupId
artifactIdmaven-surefire-plugin/artifactId
configuration
skipfalse/skip
useFilefalse/useFile
systemProperties
property
namemaven.junit.sysproperties/name
valuelog4j.configuration/value
/property
property
namelog4j.configuration/name
valuefile=:c:\tmp\log4j.xml/value
/property
/systemProperties
/configuration
/plugin
---
and
plugin
groupIdorg.apache.maven.plugins/groupId
artifactIdmaven-surefire-plugin/artifactId
configuration
skipfalse/skip
useFilefalse/useFile
systemProperties
property
namemaven.junit.sysproperties/name
valuelog4j.configuration/value
/property
property
namelog4j.configuration/name
valuec:\tmp\log4j.xml/value
/property
/systemProperties
/configuration
/plugin
--- and (log4j.xml is in same directory as pom.xml) this does not work either.
plugin
groupIdorg.apache.maven.plugins/groupId
artifactIdmaven-surefire-plugin/artifactId
configuration
skipfalse/skip
useFilefalse/useFile
systemProperties
property
namemaven.junit.sysproperties/name
valuelog4j.configuration/value
/property
property
namelog4j.configuration/name
valuelog4j.xml/value
/property
/systemProperties
/configuration
/plugin
---
none of these work. Any ideas on how to integrate Maven2, Log4J and Junit would
be greatly appreciated.

Re: Log4j and Serializable classes
I don't quite understand. Do you want to serialize log4j classes? Anytime that you serialize an object both the client and server need all classes that the object uses. If the object has a log4j Logger than both the client and server should have log4j.jar in the classpath.

Re: Missing loggers from getCurrentLoggers() under WAS 5.x
The difference can probably be explained as a difference in LoggerRepositories. There is a servlet (LogWeb?) that allows config changes so it migh have some clues to help you. On 1/19/07, Ostermueller, Erik [EMAIL PROTECTED] wrote: Hello, I'm writing some code that will turn log4j(1.2.8) logging on and off at runtime. I'll probably expose this via jmx. I've seen solutions out there to re-read a configuration file and this is not what I want to do. Instead, I want the code to discover all the loggers in use by my EAR (deployed under WAS 5.x ) and enable the JMX user to: -view the list of all loggers -set the logging levels on any one of the loggers. Under jonas, this works like a dream. Invoking myLogger.getLoggerRepository().getCurrentLoggers() unleashes a gusher of loggers of every variety. hibernate, struts, betwixt, etc... I can pick over the results and invoke setLevel() on the ones I care about. Logging levels are jumping up and down and the world is a happy place. Enter WebSphere Application Server 5.x [thunder, lightning, dark clouds]. With WAS, the getCurrentLoggers() returns just a small subset of all the loggers in use. The ones I mentioned above, for instance, are ones that show up in jonas but not websphere. The ones in my own package space are there in both jonas and websphere. So why did some disappear and not others? Where did they all go? -- we use struts and the others equally in both jonas and was. Using the following WAS add-on (a classloader viewer), I'm probably going to find my missing loggers. http://ecommunity.groupintelligence.com/websphere/forums/showthread.php? p=2353#post2353 My question is, what should I do next if I do find them? I suppose I'll try to find an api to traverse the classloaders, but that sounds plain nasty. Surely someone has done this before. I've posted this question on a WebSphere forum and I didn't get as much as a peep out of them. http://ecommunity.groupintelligence.com/websphere/forums/showthread.php? p=2353#post2353 The people who wrote the following doc seem to know what they're talking about: http://mattfleming.com/files/active/0/ibm.pdf I tried their JCL option 3 + EAR and unfortunately, the hibernate and other loggers were still missing. If anyone thinks it will help, I could post the lists of loggers that did/didn't show up.

Re: Confirm successful reading of a conf file, check if loggers and appenders were instatntiated
I believe the reason that log4j configuration doesn't thow exceptions is that normally logging isn't the core reason for the program and a problem with logging shouldn't stop the program. If you look through the API I believe you will find methods to obtain attached appenders so you could verify that way (but then your code would have to know about your config). On 1/18/07, Marcel Gołuński [EMAIL PROTECTED] wrote: Hello. I made a little research before posting here. And i didn't find any interesting answers. Major question: (from log4j wiki's FAQ - not answered (http://wiki.apache.org/logging-log4j/FrequentlyAskedQuestions) ) How can I get notified of errors during configuration and then handle them? For example, I want to log to a file but the directory does not exist yet. I want to catch that configuration error, create the directory and restart configuration. (from wiki's requested features (http://wiki.apache.org/logging-log4j/Log4jRequestedFeatures) ) PropertyConfigurator.configure() and doConfigure() methods should return some sort of status to know if the loaded properties are valid. I'm using DOMConfigurator (configureAndWatch) to read a conf file for a jboss webapp (log4j1.2.8, checked 1.2.14 nothing changed). I want to know if the reading was successful. I think that there is no exeption thrown (even if file does not exist, not only on validation errors). my questions: - Is there any way to check if the conf file was read successfully (I may switch to properties configuration if it is supported there) - Is there any way to check on configureAndWatch that file was actually reread and configuration changes were made. (For example to attach some actionPerformer to log4j configureAndWatch which will be triggered when reading occures.) (I suppose no)? - Minor questions: NOTE: I know that file appenders throw exeptions so it is easy there. How can i determine that appenders and loggers were instantiated (created)? my idea (not checked but i think working): - logger org.apache.log4j.LogManager method: exist() - appender (after attaching to a logger) org.apache.log4j.Logger (exactly Category super class) methods: isAttached(), getAppender(), getAllAppenders() (and Enumerate for the one im trying to check) Is there any other way (easier, faster) to determine that loggers and appenders were created and attached succesfully? Its a pity that log4j does not support exceptions, but i understand the performance issue, and think that it is connected with the lack of exceptions. Sorry for my English.

Re: Confirm successful reading of a conf file, check if loggers and appenders were instatntiated
Could the configure method be changed to return a boolean indicating sucess? If someone detected that configuration failed, would log4j be in an undefined state so that configuring with another file might not produce the desired results? One way to detect config problems would be to run with -Dlog4j.debug and capture and parse System.out info produced by log4j.

My understanding is the lack of exceptions from the configurators was not motivated by performance concerns, but that a bad configuration file would not cause an otherwise working application to fail. Unfortunately, that design decision makes it difficult to programatically respond to configuration failures, like providing a backup configuration if the configuration file was missing. I did start an experimental project (search for strictxml) in the sandbox for new XML configurator that used a stricter syntax and provided more feedback on the processing of the configuration. However, that has been dormant for a while and probably will not see much addition effort until log4j 2.0 development starts whenever that is. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- James Staufferhttp://www.geocities.com/stauffer_james/ Are you good?

Re: cannot write to a file with rollingfileappender in log4j1.3
