Hi Jake, First thanks for your quick reply.
What do you mean ensuring each application will use their own respective configuration? Is it by reconfigure it using DOMConfigure / PropertyConfigurator explicitly inside each application? After read your URL about logger repository, i'm quite surprise that the first line in the URL says : "Log4j, by default, uses a single logger repository. So, unless you log within the context of your own custom logger repository, the last entity to configure Log4j will have configured Log4j for every app using the default logger repository." well, that's why other application's configurations also affected after i configure my log4j inside my application. Thanks for your reply.

Most application servers don't use child-first, or parent-last, classloading for webapps by default. Tomcat Standalone is one of the only ones out there that does this by default. Hence, it is usually quite simple to separate logging per/application under Tomcat. Other appservers may have options to use child-first classloading. However, many times you'll run into other issues because it's not well supported on other platforms. I presume each app is manually configuring iteself? For appservers like Weblogic of Websphere, I suggest you put both log4j.jar and log4j.xml in the server classpath and get rid of manual configuration code in your apps. If you want to explore true logging separation and be able to continue to manually configure without affecting other apps, then you can look into using a repository selector. However, the concept is confusing for many and may be more effort than it is worth. I'll let you decide... http://wiki.apache.org/logging-log4j/AppContainerLogging Jake On Wed, 13 Aug 2008 03:50:09 -0700 (PDT) lanes <[EMAIL PROTECTED]> wrote: > Hi All, > > I got a strange behavior when i deploy my application > that define the log4j.xml configuration to existing App.Server (say it > IBM WAS v6.1) then other application's log that already use their own > log file for example App A log to A.log, App B log to B.log will > suddenly redirect to SystemOut.log and no longer to their respective > logs file. > > But when i undeploy my application from the App Server, then other >application's log file come back to normal. > > Below is my log4j.xml configuration : > > <?xml version="1.0" encoding="UTF-8"?> > <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> > > <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/";> > > <!-- Appenders --> > <appender name="console" > class="org.apache.log4j.ConsoleAppender"> > <param name="DatePattern" value="'.'yyyy-MM-dd"/> > <param name="Append" value="true"/> > <param name="Threshold" value="debug"/> > <param name="Target" value="System.out" /> > <layout class="org.apache.log4j.PatternLayout"> > <param name="ConversionPattern" value="%-5p:%d:%c{1} [%x] - >%m%n" /> > </layout> > </appender> > > <appender name="my_file_a_log" >class="org.apache.log4j.DailyRollingFileAppender"> > <param name="File" > value="my_file_a_log.log"/> > <param name="DatePattern" value="'.'yyyy-MM-dd"/> > <param name="Append" value="true"/> > <param name="Threshold" value="debug"/> > <layout class="org.apache.log4j.PatternLayout"> > <param name="ConversionPattern" value="%-5p:%d:%c{1} [%x] - >%m%n" /> > </layout> > </appender> > > <logger name="mycom.mypackage.ClassMyClass" additivity="false"> > <level value="info" /> > <appender-ref ref="my_file_a_log" /> > </logger> > > > <root> > <priority value="warn" /> > <appender-ref ref="console" /> > </root> > > </log4j:configuration> > > Is it correct? > Am i missing something? > > My other question is why other application is affected to my log4j.xml >configuration? > I though every application inside the App.Server will have their own >respective configuration? > > Please help me. > your help is really appreciated. > > regards, > Lanes > > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
