Hi,
I got the following error message when I use the JBoss2.4.4 with Tomcat 4.0.1 to run our application.
In fact, our application also use the log4j for logging but we cannot run smoothly and having this exception.
Is there any conflict for all log4j work together in these parties? Any idea for fixing this problem.
Your prompt response is appreciated. Thanks in advance.
