Application specific Log4j in seam

[parimal.parimal.chauhan.criti.in]

Hi,
I am developing seam application and need to configure the log4j for that.I do not know how to configure the log4j such that only my application specific logs is captured (not whole jboss log) in separate file. (i.e. myappdebug.log)

Can anyone please show me the steps in seam application ?.

Thanks in advance.

There is nothing different in configuring log4j for seam or log4j for a non-seam application. And afaik, you cannot configure log4j to just log you application related info to a separate file. You can log your specific package logging to another place by configuring an appender, but that is log4j and has nothing to do with seam.

I think this is what you are looking for.

You can compare "jboss-4.2.3\server\default\conf\jboss-log4j.xml" with the one as below.

I am capturing my application specific log... refer section
a) "<!-- APPLICATION specific, A size based file rolling appender -->
<appender name="myappdebug_FILE" class="org.jboss.logging.appender.RollingFileAppender">"

b) Under "<!-- Limit categories -->" replace "com.myapplication" with your package.

c) Provide log.debug in your code and then restart, it should create separate log file under "jboss-4.2.3\server\default\log"

Note : I have also made INFO to ERROR (like com.arjuna.ats) under Limit categories to reduce the size of log.

Let me know.

UPDATED jboss-log4j.xml (Not sure how to attach file, so pasting it here)

I am just doing that but my application specific log file remains empty, nothing gets logged. All messages including my application's are still being logged under the 'FILE' appender, i.e. server.xml.
Is there any solution to this?
