RE: log4j and WSAD 5.0 anomalies and problems
Of course, that code is only executed if the default Logger initialization from a
properties file is not performed. Apparently, your log4j.properties file is not being
found.

The culprit is the following code from
org.apache.commons.logging.impl.Log4JCategoryLog
private void initialize() {
Category root=Category.getRoot();
Enumeration appenders=root.getAllAppenders();
if( appenders==null || ! appenders.hasMoreElements() ) {
// No config, set some defaults ( consistent with
// commons-logging patterns ).
ConsoleAppender app=new ConsoleAppender(new PatternLayout( LAYOUT ),
ConsoleAppender.SYSTEM_ERR
);
app.setName(commons-logging);
root.addAppender( app );
root.setPriority( Priority.INFO );
}
initialized=true;
}
As you can see it sets the level (a.k.a. priority) of root logger (a.k.a. category) to
INFO.
This problem has been reported as bug #13201 to commons-logging.

So , now I know that my DEBUG is NOT enabledbut I do not know
why. It appears to me that log4j isnt even
being called anywhere..simply because 1) i tried changing
ConversionPattern and so no changes on the console and 2) nothing is still being
written to file.
Please, help, this is making me crazy!
Thanks, Lydia

Application Developer v 5.0?
I had to migrate my WSAD 4.03 application to WSAD 5.0, which has a
totally different tree structure, but WSAD 5.0
is supposed to recognize and retain WSAD 4.03 structures.
I am not seeing log4j initialize in the console, yet, I see the class
loggers append to the consolethe weird
thing is that I have them in the properties file logging to files - yet no files
are being created.
Maybe I dont fully understand how WSAD works with commons-logging and
log4j? I didnt think I had
to use a log4j initializing servlet which is mentioned in web.xml to make it work
- theoretically, my class
files should never have to change when I change logging tools?
Here is my setup:
I have commons-logging.jar and log4j-1.2.7.jar under the WEB-INF/lib
directory.
My commons-logging.properties file in the /WEB-INF/classes directory :
# commons logging config - use Log4J
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JCategoryLog
My log4j.properties file in the /WEB-INF/classes directory :
# log4j configuration file
# DEBUG, INFO, WARN, ERROR and FATAL
# Create three appenders, one called listout, one called stdout and
another called R
log4j.logger.com.com.ibm.lansys.actions=DEBUG, listout, stdout, R
log4j.logger.org.apache=DEBUG, listout ,stdout, R
# Create root (default) appender -default DEBUG and higher msgs go to the console
log4j.rootCategory=DEBUG, stdout

RE: Log4J in JSP??
Hmm. I
try to avoid 'method repositories' where possible. I also try to put as little
Java code in a JSP as possible. That way, I find that I don't often have much of
interest to log from a JSP. Anyway, here are a couple
suggestions.
First,
why not have a look at the Jakarta Log Tag Library. It may be just what you
need.
http://jakarta.apache.org/taglibs/doc/log-doc/log.html
If you
want to develop your own class, you might consider designing a JavaBean that you
could instantiate with page scope using the JSP useBean tag and use bean set
tags to set its properties -- like the name for the Category. Your bean would
have logging methods that duplicate those of Category. Itcould retrieve
the Category instance based on its name property and delegate calls to the
Category object.
Best

Jim

Sumit,
You
may want to design a class with all static methods which will do logging to
log4j. It could have a method such as
public static void doInfoLog(String catName, String
message)
{
Category cat =
Category.getInstance(catName);
//log the message to this category
}
You
could use this class and method in your JSP.
Thanks,
seemantini

Hi
guys,
This is my
first message to this list..
I just
wanted to figure out whether I could use log4j in JSPs for logging
purpose?
I have
already used log4j in Java class and
EJBs.
Thanx in

Title: RE: how can install tomcat as a service in Win 2000 Not really a log4j question, but in the true community spirit ... Have a look at the Jakarta NT Service page http://jakarta.apache.org/tomcat/tomcat-3.2-doc/NT-Service-howto.html and also the Alexandria Software JavaService tool which is referenced there http://www.alexandriasc.com/software/JavaService/index.html Between what is provided with Tomcat (usable on JDK 1.2) and the Alexandria JavaService (open source NT service Java invoker for JDK 1.3), you should be set.

Clearly by doing this, I lose log4j's ability to automatically retrieve methods, line numbers etc. from the caller. It seems like what I have to do is to retrieve this information before I add an individual log to the buffer, then send it as part of the message string to log4j. Obviously I would lose some flexibility in the PatternLayout function, but this is not crucial. I understand that log4j somehow gets this information from a stack trace, but I am unsure of exactly how this works, or how I would go about getting the information for myself.

RE: Formatting NT Event log
Title: RE: Formatting NT Event log The NTEventLogAppender could probably use some work, seeing as it doesn't currently support options. The only way, then, to set the event source is by virtue of one of the alternate constructors which permits specifying the source. The constructor will register the source. The category and event cannot currently be set. Adding the ability to set them could be problematic as there message resources must be delivered in a DLL and properly specified in the NT registry.
