RE: Re: Urgent Please--How to create different log files with different property files in same webapplication
Hi,
Thank You So much.
I am not very clear about repositoryselectors.I tried to check some examples
and tried to implement.
Our application will be used by others as a library.We will provide jsps
,jar files and some property files including log4j property file.
All our property files will be under WEB-INF of their(XYZ's) web
application.And our(abc's) jar files will be under their WEB-INF/lib.JSPs
under XYZ/abc/*.jsp's.
We are creating logs under WEB-INF/logs/abc.log
We dont have access to XYZ's log4j config file.So we cant include
loggers.What ever the changes, has to be made from our(abc) side only.I have
already sent our log4j config file.I am new to log4j also.Please let me know
if something can be done in our log4j config file.
Can you please explain me how can i handle repository selectors for this
problem.I am not able to find good examples also.
Thanks Regards,
Sivamma.

Your Implementation of repository selector is quite useless, because your
distinction criteria relies on the current classloader. Log4j's default
repository selector does this already for you. It is a singleton within
the scope of one distinct classloader. If annother classloader comes onto
stage there will be created a new repository selector automatically. So
each classloader context has its own separate logger universe which can be
configured independently (i.e. each different WEB-INF app in Tomcat has
its own classloader).
A custom RepositorySelector has it's benefits if you can extract at a
given time in code execution a unique criteria . This might differ when
the same code is executed again (i.e. might be the user id of the logged
in user, or others). How to establish this criteria is very dependent on
the architecture of your application and your goal of separating the log
outputs.
I reviewd your mail-thread and I must admit I don't quite understand the
relationship of your two applications abc and xyz. Nor do I understand
which log statements you wish to be written to the one log file and which
one to the other. If the distinction only relies on the code spot where
the log output is generated then the best approach would be to define
separate Loggers for your own classes (like james already mentioned), name
them by the fully qualified classname and set the additivity flag to
false. Like that log outputs issued by the classes of xyz app never reach
the appenders of the classes of abc app and vice versa.
But be aware: You cannot configure the same LogManager twice and hope the
second configuration adds to the first one. The second configuration
action will purge the first one before configuring new. But you can create
new Loggers and Appenders by code and add them to the first loaded
configuration.
To give more precise advices you must explain more about the architecture
of your applications.

Hi I tried to implement the repository selectors.But still
problems occurs.
Please find my repository selector below.
However i am not using Servlets to initialize the log4j.
So Even to implement repository selector i am not using servlets.
Our customers requested us to not use servlets.Since we made
everything
using Java and jsps.

Urgent Please--How to create different log files with different property files in same webapplication
Hi, I have a requirement to create different log files in same application.Our application will be used in a different web application.Even the other application is using log4j.We have our own log4j configuration property(WEB-INF/config.properties) file and separate log file in a particular directory(WEB-INF/logs/xxx.log). At present the problem is we are getting logs from other application to our log file. Our application(Giving as jar files) is under other application. For example our application is abc and others is xyz. The directory structure is webapps/xyz/WEB-INF where it contains xyz's log4j property file as well abc's log4j property file.abc's logs are supposed to go webappas/xyz/WEB-INF/logs/abc.log and xyz's logs are supposed to go different file(Which we dont know , exactly where it goes). But at present xyz's logs are coming into abc's logs means , they are coming into webapps/xyz/WEB-INF/logs/abc.log Can you please tell me how can get logs only from my applicaiton(may not be from my application..only from my classes).

Re: Urgent Please--How to create different log files with different property files in same webapplication
Hi, Thank you for immediate reply.
The problem is little different here.XYZ and abc are in same application.XYZ
is using abc's jar files and jsps.
Our application(abc) have our own log4j configuration property file at
WEB-INF folder of XYZ(WEB-INF is common for both of XYZ and abc).
We are configuring log4j from java class file.We can not add/modify/delete
XYZ's log4j configuration property file.At present we are getting even the
XYZ's logs in our log files.
Please find our log4j configuration(abc's)

It(abc) works fine as a single application in tomcat6.
But when XYZ starts using abc the problem occurs(XYZ is using Weblogic
Application server).
Is there way to get separate the logs in a same application with different
log4j configuration property files.

Sivamma

If they are in the same web app then they probably have different
logger name roots so you can configure each to use a different
appender. (i.e com.abc uses one appender and com.xyz uses another
appender).

in abc , we are referring a config file through our code.

Re: Urgent Please--How to create different log files with different property files in same webapplication
Can you please explain me more.How to implement repository selectors.Please send me some examples. I tried to find in FAQs and some docs.But its not clear to me. Thanks Regards, Sivamma. So does only your customer have the problem of mixed logs? It sounds like they just need to change their config if they don't want mixed logs. But knowing how customers can be repository selectors might keep the logs separate without the customer changing their config. -- View this message in context: http://www.nabble.com/Urgent-Please--How-to-create-different-log-files-with-different-property-files-in-same-webapplication-tf3974952.html#a11288789 Sent from the Log4j - Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
