Subject Re: Application specific log4j issue

I haven't worked with log4j and geronimo in long time but ensure that both the application
use different classloaders. 

So check the classloaders being used in both applications.

Hope this helps

Hi Chi,

Thanks for the response.

However i am still facing same problem. Logs of both the application is
going into one log file.

I tried the solution proposed by you. Following is the plan file which i am
using during deployment:

(See attached file: geronimo-web.xml)

Please let me know if i am missing something.

log4j.appender.FILE.File=${catalina.home}/logs/logs.log is used to define
where you log file is. Since you want application specific log
configuration. You need to define different log4j.appender.FILE.file
attributes in order to make sure application logs into its own log
file.Then use ApplicationLog4jConfigurationGBean to define where your is.

The problem that both the application goes into one log file, which was
created last, might be caused that both your application use the same
package name, such as Thus, the log4j instance will use the same
key as,FILE.  You can "hide" the parent log4j
instance of Geronimo server by using <hidden-classes/> element in your
deployment plan. Accordingly, you should add the dependency of log4j as
followed to initiate separate log4j instance for your application.



Hope this helps. Anything incorrect, please chime in.
