Re: ms sql server and log4j problems
I believe the problem is with syntax of your SQL statement, not w/ log4j per se
try putting commas between your VALUES in your SQL statement.

Re: Mapped Diagnostic Context in Struts Action Class
I have done what you are attempting with no unexpected results... i.e.,
UserA maps to address 1 and UserB maps to address 2 just fine.
The ability for this to work correctly really lies more with the Thread
strategy employed by your servlet engine, and less on Struts in order
for this to work as designed you need to make sure that your Servlet engine
is configured to use a multi-threading model (which is the out of the box
default for most...)

Hi, this is a combination question about both log4j and struts.
For the MDC is managed on a per thread basis, we can use it to log the user
IP address in the web application.
While, as I remember, struts action class is designed to be thread-safe.
If I try to log the user IP address in the execute () method of struts
action class,
For example
public ActionForward execute(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest request, HttpServletResponse response)
throws Exception {
String username=session.getAttribute(user);
MDC.put(userip,request.getRemoteAddr());
logger.info(username+ login);
..
}
Will the unexpected case happen?
1. UserA from 192.168.0.1 login, and the MDC put 192.168.0.1 to the MDC
2. UserB from 192.168.0.2 login, and the MDC put 192.168.0.2 to the MDC(now
the userip in MDC is updated)
3. UserA executed the code logger.info(username+ login);
4. UserA executed the code logger.info(username+ login);
so the log4j output maybe look like
[192.168.0.2] UserA login
[192.168.0.2] UserB login
Actually the assumption is
[192.168.0.1] UserA login
[192.168.0.2] UserB login

RE: logging JDBC objects
Re: Public info You are correct, although one can attempt to cheat a bit and get access to private material by calling the AccessibleObject.setAccessible() method to force an override.

RE: Log file location
Re: Bug in jBoss
Alas. Actually/unfortunately the 2.3 (and 2.4 proposed final draft) Servlet
spec only 'suggests' that the Containers ClassLoader give preference to the
WebApp (http://www.jcp.org/aboutJava/communityprocess/final/jsr053/):
SRV.9.7.2 Web Application Classloader
...It is recommended also that the application class loader be
implemented so
that classes and resources packaged within the WAR are loaded in
preference to
classes and resources residing in container-wide library JARs.
Note the use of the word 'recommended' and not 'required'
FWIW, I have always ended up punting on this one and placing my log4j
configuration into the jBoss server's log4j.xml file. Perhaps jBoss 4.X
has addressed this (I have not used it yet)?

Well, if you your app is seeing jboss/lib/log4j.jar in preference to
WEB-INF/lib/log4j.jar, then there is a bug in JBoss. The Servlet spec
states that (contrary to the normal Java2 classloading scheme) classes and
libraries in WEB-INF/classes and WEB-INF/lib are checked first for
classloading and if the classes are not found there, only then does it
look to a higher classloader to attempt to load the classes.
I know JBoss has some concept of a single classloader across the whole
server (I think that is what I read), but if it doesn't allow for a
separate WebappClassLoader, then I think it is a spec compliance
violation. What does the JBoss group have to say about this? Putting
log4j.jar in WEB-INF/lib *should* provide a completely separate logging
environment from the one JBoss uses.

Hi Jake,
Thanks for the information. I have gone through the stuff you've written.
Here's what I'm doing:
1. I placed log4j-1.2.8.jar in WEB-INF/lib
2. I placed log4j.properties in WEB-INF/classes
3. I deployed the application on JBoss 3.2.1
By default, JBoss has log4j.jar in jboss/lib which is in my classpath.
So, even my application class loader takes the classes from log4j.jar
located in jboss/lib?
If I remove log4j.jar in jboss/lib, then I think I will not get server
log of JBoss.
How to solve this issue? Please inform.

Hi Sriram,
Do you have log4j.jar in WEB-INF/lib? If not, I'd expect default
initialization not to work. Remember that the webapp class loader can see
parent class loaders, but the parents cannot see the webapp class loader,
hence your log4j.properties will definitely not be found. If you are
trying to use log4j.jar in a parent class loader and want your own
configuration file to be used in your own logging space, then you will need
to use a repository selector. See the log4j-sandbox for working
examples. I wrote something up about this stuff here...

Still it's not being read.
I am JBoss and JBoss contains log4j.jar by default and it has log4j.xml
in
default/conf folder.
Probably even my application is taking log4j.xml from that location by
default. I need to check that. Anyone who has implemented log4j for their
applications on JBoss, pl. suggest.

Hi,
I am unable to set log file location. I searched the forum for old

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
