I actually found a solution for this at
http://www.mail-archive.com/[EMAIL PROTECTED]/msg04582.html.
Although I don't completely understand the solution it seems to work. Here
is the new servlet code that initializes my webapp logger.
****************************************************************************
******
public void init(ServletConfig config) throws ServletException {
LoggerRepository repos = LogManager.getLoggerRepository();
InputStream is =
config.getServletContext().getResourceAsStream("log4j.properties");
Properties prop = new Properties();
try {
prop.load(is);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
PropertyConfigurator.configure(prop);
}
****************************************************************************
*******
I'm not sure what "LoggerRepository repos =
LogManager.getLoggerRepository()" does. My guess is that since jboss uses
log4j for it's internal logging that my webapp is unable to use the
"default" LoggerRepository and LogManager.getLoggerRepository() returns a
new instance of a LoggerRepository specific to the context of my webapp.
This is mostly a guess and I'll have to do more investigation. In any event
my immediate problem is solved.

I am not sure but I think that you should not try to
write directly to
the file system from j2ee.
I do not think that your configuration file is used by
jboss.
Use jboss log4j.xml configuration it works great.

Subject: log4j in jboss
Hi,
I'm attempting to set up logging using log4j in a
jboss servlet. The
code from my servlet looks like this:
************************************************************************
****
**********************************************
private void initLogging() throws IOException {
PrintWriter out = response.getWriter();
InputStream is =
session.getServletContext().getResourceAsStream("log4j.properties");
Properties prop = new Properties();
prop.load(is);
PropertyConfigurator.configure(prop);
Logger logger =
Logger.getLogger("com.tclick.agencyManagement.search.SearchParams");
logger.debug("Test");
************************************************************************
****
***************************************************
My properties file looks like this:
************************************************************************
****
****************************************
# Set root logger level to DEBUG and its only appender
to AMS.
log4j.logger.com.tclick.agencyManagement.search.SearchParams=DEBUG,
AMS
log4j.logger.com.tclick.agencyManagement.search.DistributionSystemsSearc
h=DE
BUG, AMS
# AMS is set to be a RollingFileAppender
log4j.appender.AMS=org.apache.log4j.RollingFileAppender
log4j.appender.AMS.File="c:\\agencyManagement.log"
log4j.appender.AMS.MaxFileSize=100MB
log4j.appender.AMS.DatePattern='.'yyyy-MM-dd
log4j.appender.AMS.MaxBackupIndex=1
# AMS uses PatternLayout.
log4j.appender.AMS.layout=org.apache.log4j.PatternLayout
log4j.appender.AMS.layout.ConversionPattern=%-4r [%t]
%-5p %c %x - %m%n
************************************************************************
****
******
The servlet has no problem actually finding the
property file. Once I
have the property file loaded I have no problems
grabbing values from
the property file and
displaying them using the servlet's PrintWriter.
The problem is that the log file never gets created
and nothing ever
gets written to it. Notice the logger.debug("Test")
at the end of the
servlet code. That never gets written the specified
log file.
As an added piece of information, jboss uses log4j
for it's internal
logging. Does this have an impact on the way I set up
my logging?
I am fairly new to log4j. My goal is to be able to
configure log4j
here in the servlet and allow the rest of the webapp
code to be able to
grab instance of these loggers using the
Logger.getLogger(<class>) call.
Thanks in advance
Roger Tucker
