Re: Geronimo 2/Log4j question
I am also having this issue. In tomcat I just needed a log4j.xml in my
classpath, however geronimo seems to ignore it.
The only solution I've found is to have Spring configure log4j through the
web.xml but that takes over all logging in geronimo. I need to have
separate logging for each of my web apps.
Has anyone figured out a way to get this working?

Re: Geronimo 2/Log4j question
Posted by David Jencks <da...@yahoo.com>.
This gbean is now available in the 2.1.1-SNAPSHOT (branches/2.1) and
2.2-SNAPSHOT (trunk) versions. I also set up the apacheds plugin
plugins/directory/branches/1.0 to use g. 2.1.1-SNAPSHOT and the new
gbean to demonstrate segregating the apacheds logging to a separate
file.

Re: Geronimo 2/Log4j question
Posted by David Jencks <da...@yahoo.com>.
After a little more thought I realized we could make this process
more convenient by supplying a gbean. See https://issues.apache.org/
jira/browse/GERONIMO-3898
We need an example for the docs and to demonstrate that it works.
If you don't want to switch to geronimo trunk here's the basic idea
that you can implement in a listener:
private static final String CATEGORY_PREFIX =
"log4j.category.";
private static final String LOGGER_PREFIX = "log4j.logger.";
private static final String RENDERER_PREFIX =
"log4j.renderer.";
public ApplicationLog4jConfigurationGBean(String log4jResource,
String log4jFile, ServerInfo serverInfo, ClassLoader classloader)
throws IOException {
InputStream in;
//You won't have easy access to the serverInfo, so you should skip
this part and use a resource inside your war file that you can load
from the classloader
if (log4jFile != null) {
File file = serverInfo.resolveServer(log4jFile);
in = new FileInputStream(file);
} else if (log4jResource != null) {
in = classloader.getResourceAsStream(log4jResource);
if (in == null) {
throw new NullPointerException("No log4j properties
resource found at " + log4jResource);
}
} else {
return;
}
Properties props = new Properties();
try {
props.load(in);
} finally {
in.close();
}
//remove any global log4j configuration
for (Iterator it = props.keySet().iterator(); it.hasNext(); ) {
String key = (String) it.next();
if (key.startsWith(CATEGORY_PREFIX)
|| key.startsWith(LOGGER_PREFIX)
|| key.startsWith(RENDERER_PREFIX)) {
continue;
}
it.remove();
}
PropertyConfigurator.configure(props);
}
Hope this helps

Re: Geronimo 2/Log4j question
Posted by David Jencks <da...@yahoo.com>.
You have to be careful about what properties you feed to log4j..... I
did get this approach working with the roller plugin. Look for the
roller-custom.properties file in the plugins/roller/trunk stuff
have to run again, more later

Re: Geronimo 2/Log4j question
Posted by Adam Ruggles <a....@gmail.com>.
The problem with the ServletContextListener approach is that it takes over
the log4j for all apps.
For instance, I have two web apps running in geronimo. They share a common
code base. I need each one to manage their own logging. Right now using
the Listener approach, the following occurs.
WebApp 1 starts up and begins logging com.my.package
Everything looks good so far.
WebApp2 starts up and begins logging com.my.package. Now WebApp 1 is no
longer writing out to the log files and WebApp2's logs contains logging
information from WebApp1 and WebApp2.
By the way in both cases the geronimo.log file is affected as well.

Re: Geronimo 2/Log4j question
Posted by David Jencks <da...@yahoo.com>.
The solution I know of is to include a log4j.properties file if you
want to run on servers that do not use log4j internally but to have
your ServletContextListener read an app specific properties file that
sets up the appender for your app and other such customizations and
feeds the info to log4j programatically.
Roller uses this technique.
I'm not sure exactly what the log4j API for this is and have to run
now, if you can't find it I can look more later.

Re: Geronimo 2/Log4j question

I used Spring to create the listener like you've described here. It works,
but the only problem is that I have multiple web apps and I'd like them to
maintain their own log, however using this method causes the last web app to
load to take over the logging.

Re: Geronimo 2/Log4j question

Hi!
I had the very same problem with G2.0.0, currently I'm using G2.1 and
to tell the truth I don't know whether this issue still exists because
I use a very simple work around that works always and for my case is
sufficient.
Simply in WAR create a new class, implement the ServletContextListener
interface and override contextInitialized method like this:
public void contextInitialized(ServletContextEvent ctx) {
String prefix = ctx.getServletContext().getRealPath("/");
String file =
ctx.getServletContext().getInitParameter("log4j-configuration-file");
if (file != null) {
DOMConfigurator.configure(prefix + "WEB-INF/" + file);
}
}
it works in G2.0.0 and G2.1
If You manage to use Log4j without this workaround, let me know please ;)
best regards
Łukasz

I've tried both and neither works.

Have you tried to inverse-classloading and/or hidden-classes elements
in your plan so log4j and its configuration in Geronimo is for
Geronimo stuff and yours is for your stuff?
