I followed some examples on the web to use RepositorySelector to implement
separate logging for 2 applications deployed on the same instance of
weblogic server. I have the Lgo4j.properties file under Web-Inf/ folder,
This is loaded through web.xml file through a startup servlet. Problem is
logging is taking place either in Log4j.log file or other applications log
file. In each java class file, I use..
private static Logger log = Logger.getLogger(LoginFilter.class);
and call the log .info ..accordingly. In log4j properties file, only
difference is file name for 2 applications.
I am using weblogic 8.1.6 and Log4j 1.2.8 versions
thanks for the help
