Using CompositeTriggeringPolicy with log4j.xml
Hello all, I want to configure a CompositeTriggeringPolicy inside my log4j.xml, but I have not been able to find any documentation on how to pass individual triggering policies to it. The Javadoc doesn't seem to address the issue. Could anyone please give me a short example of how this is supposed to be done?

Relative path of file appender
The following log4j.properties uses a relative path for redirected file. Is
it valid?
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=./output.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=5
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L -

Re: Getting Could not find root logger information but I don't see why
Is that a literal path?
...\my.ear\my.war\WEB-INF/log4j.xml
First, it's invalid since it has 3 periods, rather than 1 or 2. Second, your
slashes are inconsistent. If you want to be agnostic to the OS, just always
use forward slashes (/), which will work under both Unix and Windows in
Java. Third, when using relative paths, the path is going to be relative to
the directory from which the JVM started. So, let's say this is...
${weblogic.home}/server/bin
Log4j would be looking for your file in
${weblogic.home}/server/my.ear/my.war/WEB-INF/log4j.xml
...which is almost certainly incorrect.
Also, keep in mind that because you are not [likely] using a logger repository
selector, you will be using the default logger repository unless you are using
child-first, or parent-last, classloading. If you want per/webapp logger
configuration, this is a must. Otherwise, you might as well place log4j.xml
in the server's classpath. And if you aren't doing anything special regarding
setting runtime properties for you configuration to use, then it is rather
pointless to use a custom Log4j init servlet. Just place log4j.xml in
WEB-INF/classes and be done. Log4j will automatically pick this up and use
it.

Re: using of system properties in subject of SMTPAppender
You might be interested in the it.openutils.log4j.AlternateSMTPAppender
[1]. It allows for dynamic subjects and more. Note that I am not affiliated
with this project. I just found it to be useful.

Hi,
I have a 1 server app and many clients app on different servers.
Obviously I wanted to know from which server the email comes, so I used
this:
log4j.xml
appender name=email class=org.apache.log4j.net.SMTPAppender
param name=BufferSize value=512 /
param name=SMTPHost value=my_smtp_host /
param name=From value=AutoBot /
param name=To value=my_em...@someserver.com /
param name=Subject value=Agent on [${HOSTNAME}] has encountered
error /
layout class=org.apache.log4j.PatternLayout
param name=ConversionPattern value=%d{HH:mm:ss} [%t] %p %C
(%L) %x - %m%n /
/layout
filter class=org.apache.log4j.varia.LevelRangeFilter
param name=LevelMin value=error /
param name=LevelMax value=fatal /
/filter
/appender
and since system property has to be setup before configuring log4j, I use
this in my code.
Main class
//create system property to hold server name
System.setProperty(HOSTNAME, InetAddress.getLocalHost
().getCanonicalHostName());
//reconfigure log4j so it picks up HOSTNAME property
DOMConfigurator.configure(getClass().getClassLoader().getResource(
log4j.xml));
Then Im receiving emails with subject like this: Agent on [127.0.0.1] has
encountered error.
So far so good.
And now I have request to include customer name in subject.
I have no problem to include it in stack trace, but since I cannot set
customer name the same way
as I did with IP (there are multiple customers handled by my app so I
cannot just use System.setProperty(CUSTOMER, SOME NAME)).
I though of solution to set this property when exception is catched and
reconfigure log4j after setting proper customer name into system property.
But I think it is politelly said ugly.
Can some1 suggest a better way maybe?
Thanks, Zbynek

Re: Getting Could not find root logger information but I don't see why
Due to some other constraints, I appear to be forced to have my log4j.jar at both the EAR and WAR classpath level. In my WebLogic config, I'm doing everything I can to make it prefer the jars in the webapp. If you are using Weblogic 9.2+, then you may be able to use a FilteringClassLoader [1], so that application library contents of the EAR file are loaded in preference to those from the server classpath. In META-INF/weblogic-application.xml you'd add the following prefer-application-packages package-nameorg.apache.log4j.*/package-name /prefer-application-packages You'd simply make sure to place log4j.jar in the EAR's APP-INF/lib or add it as a manifest Class-Path entry in the EAR's manifest.mf. Note that I haven't verified whether this actually achieves per/app logging configuration. Maybe you can try it out and report results?

This whole issue became somewhat moot when I discovered that the other library, which said it uses Log4J, is actually directly using java.util.logging, so I was able to implement a separate configuration setup for that. However, it's only a matter of time before we end up with more than one webapp using log4j. I'll have to dive into this again when we get to that point. I'm familiar with all of the prefer elements in WebLogic's config, so we'll see what happens.
