log4j set up and usage?
Where can I find an example of setting up and using log4j under commons-logging for struts 1.1? I have used log4j before and want to continue using it. Dean Hoove - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: log4j set up and usage?
http://jakarta.apache.org/commons/logging/guide.html is the help for logging+log4j. Mainly it should just be having log4j in some way in the classpath, though -Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger looks useable too.

Re: log4j set up and usage?
If the logging docs aren't enough, the commons-users or the log4j lists would be better. People shouldn't be mailing a developer directly as it benefits no one.

RE: [OT] RE: log4j integration
hi!
I am still not clear as to where I need to write this class or method.
Will it not suffice to give the entries in the web.xml file itself.
This is the first time I am dealing with these, so please help.
What I have done till now is to get the static logger instance in the class
and then put the logger.debug(xx); prints.
I need to know this :
a) In the struts framework, will it not suffice to just put entries in the
web.xml
If not, then where in the framework should I write my class that uses the
log4j apis?

Yup, that should work just fine. If you want to be able to modify the config
info while the app is running (e.g. turn on debugging in production without
reloading the app), here's another approach.
Create a directory and place it on the app server's classpath. For WLS
(depending on how you do your install and create your domains), it might be
something like C:\bea8\user_projects\domains\dotech\applib.
For each app, place a unique Log4j config file in the directory. For example,
app1-log4j.xml and app2-log4j.xml.
In your app's web.xml file, include context-param or env-entry
elements for
the name of the config file and the watch delay value:
env-entry
descriptionLog4j resource file name/description
env-entry-namelog4j/resource/env-entry-name
env-entry-valueapp1-log4j.xml/env-entry-value
env-entry-typejava.lang.String/env-entry-type

env-entry-namelog4j/watchDelay/env-entry-name
env-entry-value3/env-entry-value
env-entry-typejava.lang.Long/env-entry-type
/env-entry
Finally, create a context listener (or startup servlet) to perform the
configuration:
ClassLoader cl = Thread.currentThread().getContextClassLoader();
Context initCtx = new InitialContext();
Context envCtx = (Context)initCtx.lookup(java:comp/env);
String log4jResourceName = (String)envCtx.lookup(log4j/resource);
URL log4jResourceURL = cl.getResource(log4jResourceName);
String contentType = log4jResourceURL.openConnection().getContentType();
String fileName = log4jResourceURL.getFile();
Long log4jWatchDelay = (Long)envCtx.lookup(log4j/watchDelay);
long watchDelay = log4jWatchDelay.longValue();
if (application/xml.equals(contentType)) {
DOMConfigurator.configureAndWatch(fileName, watchDelay);
} else {
PropertyConfigurator.configureAndWatch(fileName, watchDelay);
}
It's not so bad with some additonal help from Ant. I've also used this
approach
to make it a bit less painful for multiple developers to share a single WLS
instance during development.
Quoting Chappell, Simon P [EMAIL PROTECTED]:
Jacob,
We use log4j 1.2.8 and we include the jar file right in out WEB-INF/lib
directory of our application. The log4j.properties file then lives
inside the
WEB-INF/classes directory. This works well for us on IBM's WAS 4.x.
I've never seen anyone recommend having log4j at the container level, so go
with it at the application level and forget about conventional wisdom! :-)
Hope this helps.

Hi Shankar: Two other people asked this same question so if you don't mind, I'll post my (simple) solution to the list. Btw, for those who don't remember, this is a way to enable changes in log4j.properties to be seen by the application without a server reboot. Here goes: 1. Create a simple action class say ReloadLog4jAction with just a couple of statements in the perform/execute method: Create a new LogManager, then call its resetConfiguration() method. (Write the class within the application context where you want your log4j.properties file reconfigured) 2. Create the appropriate action mapping in your struts-config.xml, so that (say) /admin/reloadLog4j.do would map to this class and maybe redirect to an OK page. (am following the way /admin/reload.do works). 3. Reload struts-config either by server restart (or simply by calling /admin/reload.do if you have that mapping in your struts-config.xml.) Of course you will need to do this just once.. 4. Make any changes to your log4j.properties file and then point your browser now to the url /admin/reloadLog4j.do. The log4j.properties file will then be reloaded and after your OK page displays, the new log4j.properties file will then be read in.

Re: log4j integration
Please forgive this note if it seems too obvious and I have misunderstood your question/comments.. If you think of both struts and log4j as just a bunch of Java packages/classes, then you will see that integrating struts with log4j is really nothing unusual. The log4j jar (or classes in the jar) needs a log4j.properties file (the name of this file is most probably hard-coded in the classes in log4j jar, which is why you don't need to personally tie the file with log4j) and this file should therefore be in the classpath and as you have found out yourself, this is all that is required...If for some reason you need a handle to this file, I don't see why the usual File class in the java.io package won't do the trick..? As for how to ensure that changes in your log4j.properties is made visible to struts, well, I guess you'll have to restart tomcat (or your app server)..(:( I don't believe the admin/reload.do will work (that works for changes to the struts-config.xml and such a blessing *that* is during development!!) ..

Re: log4j integration
Hi! Yes, I figured that out. But, that leaves the question open as to how do you make struts as a whole understand that changes have been made to the log4j.properties file. In fact, the question boils down to this: Where do I get the handle to the log4j.properties file(let us say, using the File class)? And once I do, will it be sufficient that I set the PropertyConfigurator method with the requisite parameters? Actually, the whole point of the exercise is to use the dynamic reloading of changes made to the log4j.properties file facility provided by log4j.

RE: log4j integration
There is LogManagerclass with LoG4j. It allows you to reset the configuration for entire LOG4J environment.And then as you said, you can reread the property file to initialise the log4j environment from the changed property file.

RE: [OT] RE: log4j integration
Yup, that should work just fine. If you want to be able to modify the config
info while the app is running (e.g. turn on debugging in production without
reloading the app), here's another approach.
Create a directory and place it on the app server's classpath. For WLS
(depending on how you do your install and create your domains), it might be
something like C:\bea8\user_projects\domains\dotech\applib.
For each app, place a unique Log4j config file in the directory. For example,
app1-log4j.xml and app2-log4j.xml.
In your app's web.xml file, include context-param or env-entry elements for
the name of the config file and the watch delay value:
env-entry
descriptionLog4j resource file name/description
env-entry-namelog4j/resource/env-entry-name
env-entry-valueapp1-log4j.xml/env-entry-value
env-entry-typejava.lang.String/env-entry-type
/env-entry
env-entry
descriptionLog4j resource file watch delay/description
env-entry-namelog4j/watchDelay/env-entry-name
env-entry-value3/env-entry-value
env-entry-typejava.lang.Long/env-entry-type
/env-entry
Finally, create a context listener (or startup servlet) to perform the
configuration:
ClassLoader cl = Thread.currentThread().getContextClassLoader();
Context initCtx = new InitialContext();
Context envCtx = (Context)initCtx.lookup(java:comp/env);
String log4jResourceName = (String)envCtx.lookup(log4j/resource);
URL log4jResourceURL = cl.getResource(log4jResourceName);
String contentType = log4jResourceURL.openConnection().getContentType();
String fileName = log4jResourceURL.getFile();
Long log4jWatchDelay = (Long)envCtx.lookup(log4j/watchDelay);
long watchDelay = log4jWatchDelay.longValue();
if (application/xml.equals(contentType)) {
DOMConfigurator.configureAndWatch(fileName, watchDelay);
} else {
PropertyConfigurator.configureAndWatch(fileName, watchDelay);
}
It's not so bad with some additonal help from Ant. I've also used this approach
to make it a bit less painful for multiple developers to share a single WLS
instance during development.
Quoting Chappell, Simon P [EMAIL PROTECTED]:

We use log4j 1.2.8 and we include the jar file right in out WEB-INF/lib

Thanks, we are having problems though with multiple applications (basically I used commons-logging/log4j on a new project, then it was decided to modify another application to also use log4j).

RE: log4j integration
Hi! In fact, I got two responses for the question as I had sent the same question twice. My mailbox was acting funny yesterday, so I had to send it twice. Well, I do have the log4j.properties file under web-inf/classes I had thought of using the PropertyConfigurator too. But, when you integrate log4j with struts, we no where mention the log4j.properties file specifically, ie, we just create the file and put it under the mentioned location. And when we use it, we do not mention the log4j.properties file anywhere in the files too. So, how to get a handle to the file? Correct me if there are better approaches to the same. Steps by which I integrated are : a)Got the log4j.jar file b)created the log4j.properties file c)created commons-logging.properties file d) used static logger = new logger(this) in the files where this is the class name.

[OT] Log4j configuration for EJB Project
Hi, I have an application containing EJB project and a Web project. I configured Log4j for my Web project by putting the log4j.jar in WEB-INF/lib directory and log4j.properties in WEB-INF/classes directory. However I have to configure log4j for my EJB project, where should I place the log4j.jar, log4j.properties file.

about log4j - RE: Example of a non-threadsafe Action?
Hi Craig,
Continue with the thread safe issue:
how about Log class? I understand that log4j itself is
thread safe (unlike DateFormat) - but I see a lot
examples that log4j logs are used as instance varibale
public final class MyAction
{
private Log log =
LogFactory.getLog(this.getClass().getName());
public ActionForward execute(.)
{.}
}
Is this thread safe?
If yes, then even we use instance variable, as long as
we access it thread-safe way (ie. sync it), it will be
ok, right? (performance is another issue)
Thanks a lot!

Thanks Craig! You certainly confirmed my
suspicions, although I would have
guessed that I could've gotten away with sharing
the SimpleDateFormat
variable since it wouldn't depend on any values
coming in from request
objects. Could you perhaps shed some light on why
it wouldn't make sense to
share it?
Because the internal implementation of
SimpleDateFormat uses instance variables
during parsing and formatting, so it's not thread
safe :-).

{

I tend to make my log variables static as well, but that doesn't change
whether it's threadsafe or not -- it just reduces the number of object
creations that happen if there's more than one instance of my class being
created.
Is this thread safe?
If the commons-logging implementation classes for the wrapper are threadsafe
(and they are), and the underlying logging implementation claims to be
threadsafe (as do Log4J, JDK 1.4 logging, and the SimpleLog implementation --
don't know about the others) than this is indeed threadsafe.
If yes, then even we use instance variable, as long as
we access it thread-safe way (ie. sync it), it will be
ok, right? (performance is another issue)
If an object is threadsafe, it should be unnecessary for you to synchronize at
all -- any required synchronzation must already be occurring inside. For
example, consider the difference between java.util.Hashtable (which advertises
itself as threadsafe) and java.util.HashMap (which explicitly states that it is
*not* threadsafe). The get() and put() calls never need to be synchronized in
the former case (even if you store the Hashtable in an instance variable of an
Action, because the class does its own synchronization internally. The
opposite is true if you create a HashMap and make it accessible from more than
one thread.
For example, note that you won't see any synchronization around calls like
log.debug() or log.trace() in the Struts code. Because the Log instance is
threadsafe, I don't need to worry about the fact that there might be two
simultaneous calls to log.debug() on different threads, processing different
requests.
In a similar vein, your servlet container guarantees that calls to
HttpSession.getAttribute() and HttpSession.setAttribute(), for example, are
thread safe ... in the sense that accessing attributes from more than one
thread will not corrupt the internal data structure that the servlet container
is using to keep track of attributes for you. You are still on the hook, of
course, to guarantee that the objects you store as attributes are thread safe,
but that's the application's issue, not the container's issue.
Does that help?
Thanks a lot!

RE: Log4J
The Category class has been deprecated and they talked about taking it out of the distribution after mid 2003 (according to the javadocs). Try using Logger instead. Not sure if this is your problem but it's still a good idea to switch over to the Logger class and if you're using a hyper-uptodate jar then it might do the trick... alan -Original Message- From: Sathish Babu K R [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 09, 2003 10:53 PM To: Struts Users Mailing List Subject: RE: Log4J hi kalra yep i have that log4j in lib folder sathish __ Do you Yahoo!?

I think my original email should make it abundantly clear on which side _I_ fall on this issue. :-) In fact, I've been known to (gasp! horror!) deploy applications into production with -g enabled in order to be able to actually turn on with java debugging enabled and remote debug the application (on an unactive node, of course) in the production environment. I've heard of people who just start their app servers with JDWP enabled all the time for this reason, but I've never actually met one. :-) In short, I've found that trying to save micro-amounts of time here and there in an application at the expense of debuggability and maintainability usually end up with a bad application that's also slow. Java enterprise/web applications are so seldom, in my experience, performance limited by the actual Java bytecode execution speed, as to make optimizing for that virtually irrelevant. There are so many other places to start optimizing rather than worrying about 5ns here and 5ns there, particularly before you go into production and know that you aren't suitably performant.

[OT] Log4J and Pre-Processor
Sorry for an off-topic post. I hope I will get an answer since this is a very active mailing list. I am using Log4J for logging in my current project with too many logging statements. I wrap every logging statements with the isDebugEnabled(), isWarnEnabled(), etc. During production , the logging level will be set to very minimum, and only critical errors will be logged. But however, the boolean comparison statements (whether or not to log) will be executed, which we feel will have a performance impact. I would like to know if it is a good idea to pre-process the java code to remove all the logging statements and then create the binary?? or to begin with, limit the number of logging statements during the development process itself?? If pre-processing the source code to find and remove logging statements.. is a better option, then can some one point me to a good java pre processor?

Re: [OT] Log4J and Pre-Processor
You might first run some load tests to see if the boolean statements do have a non-negligable performance impact. It's easy to loose something like this in the rounding, and there may be better places to spend your optimization dollars. As scientists, we should should more than feel, we should know.

Re: [OT] Log4J and Pre-Processor
Of course having any extra statements in a program is going to cost in terms of CPU time. The questions is how much. I have seen simple removeal of code, as well as addition of code make massive differences to the time it costs to run something. I have also seem it make no visible difference as well. The trick is to run it both before and after the code changes so that you can measure how big a change it is. I would suggest do a run with the logging code in, and then one without. If the difference is not great, then leave the code in as you never know when you will need it. If there is a large difference then you have to decide how important it really is. cio Derek.

You're probably wrong.
http://jakarta.apache.org/log4j/docs/index.html
Their benchmark is 5nanoseconds to do that method call to determine if a
particular logging level is enabled. If you're THAT concerned about 5ns,
your program probably has such hard performance requirements that you
designed first around performance to begin with, no?
I would like to know if it is a good idea to pre-process the java code

Don't bother. For this, you can rely on public static final boolean
member variables.
Basically, if you compile with any type of optimization on, any call
that is like this:
if(false) {
}
will be optimized away entirely (i.e. the bytecodes won't even appear in
the .class file at all). That also flows through variables:
public class Debug {
public static final boolean DEBUG_LEVEL = false;
}
public class Foobar {
public void doStuff() {
if(Debug.DEBUG_LEVEL) {
// This can never happen and won't
// be in the bytecodes.
}
}
}
So if you care THAT much about 5ns per call, do it this way (through
compilation) and let the java compiler do the work for you. For this,
even if you decide to pre-process, you don't have to pre-process.
But do you really care that much about 5ns? Are you SURE you care that
much about 5ns?

RE: [OT] Log4J and Pre-Processor
Would you rather have that 5ns, or the ace-in-the-hole where you can
debug your app in an installed production environment by turning on
(assuming you don't use the final static boolean method) the appropriate
logger? This has been extremely helpful in debugging. It also catches
lots of things you wouldn't ordinarily see, like when you add this to an
ActionListener more then once and you see your actionPerformed() get
called more then once. It's also useful for profiling.
The biggest savings with if (logger.isDebugEnabled()) { } comes when the
logger generates lots of StringBuffer objects, costing memory and
garbage collection, which will significantly impact performance more
then the if () to check whether to do it or not.

Not sure if this was mentioned, but you should configure your app to use
commons-logging and then specify in its configuration to use Log4j. That
way you can swap out logging implementations by simple configuration and
library addtions/removal (no recompile necessary).
What I do it this:

#
# Directly selects log4j logging implementation class.
org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.Log4jFactory
# Maps to a Log4J category (uses log4j.properties)
# note: org.apache.log4j.Category is deprecated in favor of
org.apache.log4j.Logger
# and requests for a Category object will return a Logger object.
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JCategoryLog
- log4j.properties
# Set the root logger level to DEBUG and its only appender to rolling
log4j.rootLogger=WARN, rolling, stdout
# Set the logger level for everything under org.apache to WARN
log4j.logger.org.apache=WARN
log4j.logger.com.company.framework.common.util.ApplicationConfig=WARN
# Set the logger level for org.apache.commons.validator.ValidatorUtil to
# FATAL because we know that errors will be generated here that we want to
# ignore (due to the fact that it is unknown whether a consumer is
personal
# or business and the validation.xml file is not set up to accomodate the
# differences)
log4j.logger.org.apache.commons.validator.ValidatorUtil=FATAL
log4j.logger.org.apache.log4j.TextLogger=INFO
# Configure the stdout appender to be a ConsoleAppender
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
# Configure the stdout appender to use the PatternLayout
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
# Configure the conversion pattern for the stdout appender
log4j.appender.stdout.layout.ConversionPattern=%d - %p %c - %m%n
# Configure the rolling appender to be a RollingFileAppender
log4j.appender.rolling=org.apache.log4j.RollingFileAppender
# Configure the name of the log file for the rolling appender
log4j.appender.rolling.File=/path/to/log/files/ldapAdminWeb.log
# Configure the maximum size of the log file for the rolling appender

# Keep one backup file of the rolling appender
#log4j.appender.rolling.MaxBackupIndex=5
# Configure the rolling appender to use the PatternLayout
log4j.appender.rolling.layout=org.apache.log4j.PatternLayout
# Configure the conversion pattern for the rolling appender
log4j.appender.rolling.layout.ConversionPattern=%d - %p %c - %m%n
then, in every classes that needs logging I do this:
public class SomeAction
extends MyBaseAction
private static Log log = LogFactory.getLog(SomeAction.class);
...
public ActionForward execute (..etc, etc...)
throws Exception{
...
...
log.debug(Delete Item: + item.getId() +

There's nothing wrong with using commons-logging in applications and other more finished products, but commons-logging is a greatly simplified API (for good reason) and in an application, you may find it worthwhile to commit to a more sophisticated logging tool (like Log4J) in order to have more powerful logging features. Are you talking about the code-level interface (i.e. Log versus Logger) or in terms of the configuration? Because in our applications, we've taken the commons-logging approach, though we initialize the commons-logging package with a complex Log4J configuration, so that we have in essence the best of both worlds: we can use the behind-the-scenes power of Log4j, with the ability to swap out logging implementations that commons-logging gives us. I've not seen much in the log-level API that's substantially different. What sorts of power are you talking about?

Specifically, in a recent application we chose to use Log4J directly rather than Commons Logging because we wanted to use Log4J's nested diagnostic context, in which you can basically store thread-local values (like current user) and have them available for all logging messages. http://jakarta.apache.org/log4j/docs/api/org/apache/log4j/NDC.html http://jakarta.apache.org/log4j/docs/FAQ.html#NDC Certainly if the commons logging API is adequate, you're probably better off using it by default, just like you're better off writing your code to use JAXP instead of a specific XML parser, if you can get away with it. The point being that the choice to commit to one api over an abstraction layer is much less important when you're writing a self-contained application than when you're writing libraries.

STRUTS LOG4J
Hi everybody... I know that one of the ways to use log4j with struts is to load a log4j.properties file at servlet container startup... But what if I have a business layer that has no direct connection to a servlet container or I want to run some stand-alone tests and logging... Do I have to have two separate ways of loading the log4j.properties file or is there a way to do it so it works in servlet container and stand-alone environment?! Thanks a lot, Todor - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: STRUTS LOG4J
easy pizzy...We are already having the same scenario. Don't use the default log4j initialization(which means just putting the log4j.properties file in the class path and forget about it.)This way you have no control over the initialization. You write a class(e.g. LogEnvLoader) and in that class load the property file(Or XMl file if you want) and initialize the log4j environment. And then you can call this initialization class form either the init method of servlet or from any model layer class.

Just one addition: I would recommend not to use log4j directly, but via the commons.logging wrapper (it's really easy and IMHO less intrusive, plus you're not limited to the log4j framework that way). Then, considering the classpath issue, it makes no difference whether you're dealing with a web or conventional application. The only thing you have to make sure is that the configuration files are being found, i.e. reside inside the classpath. Neither the classpath concept nor Log4j are web-specific in any way.

log4j configuration question
A couple quick questions: 1) Using tomcat is it possible to configure log4j to only be functional for your particular webapp? Because I put the log4j jar into my web-inf/lib directory, built a log4j.properties and put it in /web-inf/classes and set log4j's rootlogger to debug and got log messages from tns of stuff that I certainly hadn't setup to log.. just wondering. 2) I'd like to keep my log files potentially in my /web-inf/logs directory, however how can I get a handle on the realpath to that directory from the config file if I don't know where the deployed path would be?! I'm assuming I'd have to do that programmatically after the config file loads and that could be a major PITA if there are lots of log files correct? Some help and guidance in this direction would be appreciated. -David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: log4j setup
Hi
there are three ways( known to me) to load the log4j at the server startup
1.Create ur own servlet put the code in Init()and load it at the begining of your
application
2.Extend Action Servlet
3. through the following way.
I find the 3rd one better because it sound like struts way of doing it...!!
this is what we have done..
in struts config
!-- == Plug Ins Configuration == --
plug-in className=com.ff.gg.e.l.gi.ApplicationStartup /
/struts-config
ApplicationStartup.java
public class ApplicationStartup implements PlugIn {
public void init(ActionServlet servlet, ModuleConfig config) throws
ServletException {
try {
ProposalLogger.configureLog4J();
Category cat = Category.getInstance(ApplicationStartup.class);
cat.info(log4j has been properly configured on application
startup.);
} catch()
this will load and configure your log$j each time you start your server..
then i have a class which handle the logging..
public final class MylLogger {
public static String LOG4J_PROPERTIES_FILENAME_TEST =
proposalLog4j.mytest.properties;
public static void configureLog4J() {
String filename = LOG4J_PROPERTIES_FILENAME_TEST;
try {
java.io.InputStream is =
ProposalLogger.class.getResourceAsStream(filename);
java.util.Properties prop = new java.util.Properties();
prop.load(is);
PropertyConfigurator.configure(prop);
is.close();
} catch {}
Category cat = Category.getInstance(ProposalLogger.class.getName());
cat.info( Log4J logging has been properly configured using file +
filename + .);
return;
}
...
then I use these two these two methods do my logging..
public static void logError(Category category, String msg, CustomerLoggingInfo
customerInfo) {}
public static void logTiming(Class caller, long start, long end, String msg) {}
If anybody has any better idea please let us know.
thanks

RE: Generating logs w/Log4J in ActionClass
In your action class, retrieve your log instance
Log LOG = LogFactory.getLog(YourAction.class);
Then wherever you need to log:
if (LOG.isDebugEnabled()) {
LOG.debug(Log your debug msg here);
}
Replace isDebugEnabled() with whatever level you want to use.

Subject: Generating logs w/Log4J in ActionClass
I have the appropriate configurations completed to use Log4J w/Tomcat.
However, how would I invoke Log4J from within my action class to generate
DEBUG statements?
I have the following package imported:
import org.apache.log4j.*;
Any examples would be most appreciated.
Thanks in advance.

In your action class, retrieve your log instance
Log LOG = LogFactory.getLog(YourAction.class);
Then wherever you need to log:
if (LOG.isDebugEnabled()) {
LOG.debug(Log your debug msg here);
}
Replace isDebugEnabled() with whatever level you want to use.

Re: Generating logs w/Log4J in ActionClass
I just create a class that wraps the log statements and would have a
function like this:
public static void debug(String message, String aCategory)
{
Category cat = Category.getInstance(aCategory);
cat.debug(message);
}
then when I need to use this I would call something like:
MyLogger.debug(Message, this.getClass().getName());
Hope that helps.

add an attribute
private Logger log = Logger.getLogger();
to debug use
if (log.isDebugEnabled()) {
log.debug(message);
}
I think that will do the trick.

common-logging, Struts, Log4j
Hi. I have problem in using the common-logging with struts and
Log4j. I am basically lost. I have short questions, I appreciate if
anyone can help me little bit. these are the questions with examples:
The file outputfile.log that I specify in
log4j.appender.LOGFILE.File=outputfile.log where it is located?
where I find it? is it physical file?
I dont know why my configuration is not working, although I put the
following files in the classpath WEB-INF/classes/org/myclasses/:
commons-logging.properties:
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JL
ogger
log4j.properties:
log4j.rootLogger=DEBUG, rolling
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%
n
log4j.appender.rolling=org.apache.log4j.RollingFileAppender
log4j.appender.rolling.File=outputfile.log
log4j.appender.rolling.MaxFileSize=100KB
log4j.appender.rolling.MaxBackupIndex=1
log4j.appender.rolling.layout=org.apache.log4j.PatternLayout
log4j.appender.rolling.layout.ConversionPattern=%d{ABSOLUTE} - %p %
c - %m%n
What else should I specify, or configure to make it to work? I have
log4j-1.2.4.jar in my WEB-INF/lib/
Should I set any system propreties? or web.xml? or struts-config?
In my classes I am doing that:
protected static final org.apache.commons.logging.Log log =
org.apache.commons.logging.LogFactory.getLog(this.class);
if (log.isDebugEnabled())
log.debug(getMessage( + locale + , + key + ));
(How can I enable/disable the Debug or Trace?)
Thank you in advance. I am really stuck and I couldnt make it to
work. I am using tomcat 4.18

RE: common-logging, Struts, Log4j
I had the same problem and was only able to solve it by forceably loading the log4j
configuration file. I put the following in the servlet's init() method:
// get log4j property file.
java.net.URL log4jProps =
ActionServlet.class.getClassLoader().getResource(log4j.properties);
System.out.println(System.out.println - Log4j URL: + log4jProps);
// configure log4j
PropertyConfigurator.configure(log4jProps);

where I find it? is it physical file?
It should be saved under the app. server bin dir like c:/tomcat-4.18/bin.
I don't use tomcat. But websphere app. server saves this file under bin
folder.
If you want, you can give absolute path like
c:/tomcat-4.18/logs/outputfile.log.
log4j.rootLogger=DEBUG, rolling
Here you have not declared stdout as an appender.
So, all log messages (because you have lowest level DEBUG for rootLogger)
will be sent to file declared in rolling appender.
You can include stdout in rootLogger like
log4j.rootLogger=DEBUG, stdout, rolling
and check your tomcat log files to see if there is anything written before
you check
rolling file permissions etc.
Hope this helps.

Subject: common-logging, Struts, Log4j
Hi. I have problem in using the common-logging with struts and
Log4j. I am basically lost. I have short questions, I appreciate if
anyone can help me little bit. these are the questions with examples:
The file outputfile.log that I specify in
log4j.appender.LOGFILE.File=outputfile.log where it is located?
where I find it? is it physical file?
I dont know why my configuration is not working, although I put the
following files in the classpath WEB-INF/classes/org/myclasses/:
commons-logging.properties:
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JL
ogger
log4j.properties:
log4j.rootLogger=DEBUG, rolling
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%
n
log4j.appender.rolling=org.apache.log4j.RollingFileAppender
log4j.appender.rolling.File=outputfile.log
log4j.appender.rolling.MaxFileSize=100KB
log4j.appender.rolling.MaxBackupIndex=1
log4j.appender.rolling.layout=org.apache.log4j.PatternLayout
log4j.appender.rolling.layout.ConversionPattern=%d{ABSOLUTE} - %p %
c - %m%n
What else should I specify, or configure to make it to work? I have
log4j-1.2.4.jar in my WEB-INF/lib/
Should I set any system propreties? or web.xml? or struts-config?
In my classes I am doing that:
protected static final org.apache.commons.logging.Log log =
org.apache.commons.logging.LogFactory.getLog(this.class);
if (log.isDebugEnabled())
log.debug(getMessage( + locale + , + key + ));
(How can I enable/disable the Debug or Trace?)
Thank you in advance. I am really stuck and I couldnt make it to
work. I am using tomcat 4.18

Re: common-logging, Struts, Log4j
By default the property-files
commons-logging.properties
log4j.properties
are located in the directory WEB-INF/classes
Usually you put them in your workbench in the root of the Java Source
directory. If you build with ant you simply copy them there from your
chosen source directory
