Interestingly the problem is solved when I removed the
LogManager.shutdown(); from contextDestroyed() method. Now it works even if
the Logger is static.
This is how the Log4J is configured.
public void contextInitialized(ServletContextEvent event){
PropertyConfigurator.configure(event.getServletContext().getRealPath("/")+"W
EB-INF"+System.getProperty("file.separator")+"classes"+System.getProperty("f
ile.separator")+"log4j.properties");
}
Is there anything wrong with it.
Thanks for the help.
Antony Paul.
