Problem with logging separation between webapps and container
I'm using Resin Servlet Container. I have developed librairies(jar files)
that are shared by many web applications, I have put my libraries jar in the
global classpath of the servlet container. In those librairies, I'm using
log4j as logging mechanism with an xml configuration file. Everything was
working fine.
The problem I have is when I used log4j with Struts in a webapp. There is a
conflict, only the logging from the webapp works. I understand that this is
a ClassLoader issue as described in the lo4j documentation.
I don't want to configure my libraries logging in each webapp but having
this kind of logging configured at the server level.
To fix the problem, I tried implementing a custom repository selector (taken
from the sandbox by Jacob Kjome) in my webapp so that both hierarchies
worked at the same time without any conflicts. Even though it's supposed to
fix the problem, the webapp logging overwrites the server appenders. I have
this warning:
log4j:WARN No appenders could be found for logger (DbController.class).
log4j:WARN Please initialize the log4j system properly.
log4j: Finalizing appender named [CONSOLE].
Any ideas on how to make this work?

Howdy, I'm using Resin Servlet Container. I have developed librairies(jar files) that are shared by many web applications, I have put my libraries jar in the global classpath of the servlet container. You problem pretty much starts and ends here. Disk space is cheap: have each app's jars in its own WEB-INF/lib directory. Don't use the server's global classpath for your apps.

RE: Problem with logging separation between webapps and container
I moved commons-logging.properties and simpleLog.properties and if you have
a log4j.properites to /WEB-INF/Classes.
May be moving dtds /WEB-INF/dtds may help. Not sure never worked with Resin
servlet container.
And in the web.xml define:
!-- log4j parameters --

Can log4j work with J++ 6.0 from Microsoft?

Re: logging to 2 destinations
Use two separate file appenders, each pointing to its own file (eg application.log and junit.log). Then, I recommend that you define stuff in the root logger that you'd want for your most common logging activities; probably the stuff going to application.log. After that, define a logger for your junit tests. Provide a reference to the junit appender, give it a level, and set additivity to false such as... logger name=test.com.mycompany.mypackage additivity=falselevel value=debug/appender-ref ref=JUnitAppender//logger That will end up acting, essentially, as the root logger for your junit tests and you will have entirely separated logging for application and junit classes.

How could I put the log4j.properties file in /WEB-INF/classes/config directory? What do I have to do? Thank you. If you are going to create a config dir, why not do it directly under WEB-INF rather than where classes are put? You can load up an input stream using context.getResourceAsStream(WEB-INF/config/log4j.properties) and feed that info a Properties object, then send that into PropertyConfigurator.configure(Properties) or load up a URL using context.getResource(WEB-INF/config/log4j.properties) and send that info PropertyConfigurator.configure(URL). Of course you can still do this even if you leave the config directory under WEB-INF/classes and use the same technique above. Whatever you feel comfortable with. I just like not cluttering my classpath with non-classes. Jake - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Problem with logging separation between webapps and container
I'd listen to Yoav here and keep your libs with each app. However, I'm
wondering why this isn't working for you. What does your repository
selector use to distinguish different logger repositories? Are you sure it
is actually being used by your webapp? Note that commons-logging does some
crazy stuff and could be interfering here. commons-logging is almost
reason enough to avoid using Struts, if you ask me (but you didn't, so I
won't go on).
I've done plenty of testing where log4j.jar is in a global classloader
which many webapps use and the repository selector stuff works like a charm
to separate logging without having to put log4j.jar in each
webapp. However, I haven't much tested the case where those webapps share
other libraries in a global classloader, simply because it isn't a very
controllable environment for a webapp. Maybe you can keep testing to make
sure your repository selector is doing what you think it is doing but, in
the end, I'd still follow Yoav's advice.
