Maybe you can configure your log4j with xml files and initialize the log4j
configurator with a ClassLoader as it is explained in the documentation.
I'm sure you need some servlets for your EJBs ?
Initialization servlet
It is also possible to use a special servlet for log4j initialization. Here
is an example,
package com.foo;[PARA][PARA]import
org.apache.log4j.PropertyConfigurator;[PARA]import
javax.servlet.http.HttpServlet;[PARA]import
javax.servlet.http.HttpServletRequest;[PARA]import
javax.servlet.http.HttpServletResponse;[PARA]import
java.io.PrintWriter;[PARA]import java.io.IOException;[PARA][PARA]public
class Log4jInit extends HttpServlet {[PARA][PARA] public[PARA] void init()
{[PARA] String prefix = getServletContext().getRealPath("/");[PARA]
String file = getInitParameter("log4j-init-file");[PARA] // if the
log4j-init-file is not set, then no point in trying[PARA] if(file !=
null) {[PARA]
PropertyConfigurator.configure(prefix+file);[PARA] }[PARA] }[PARA][PARA]
public[PARA] void doGet(HttpServletRequest req, HttpServletResponse res)
{[PARA] }[PARA]}
Define the following servlet in the web.xml file for your web-application.
<servlet>[PARA] <servlet-name>log4j-init</servlet-name>[PARA]
<servlet-class>com.foo.Log4jInit</servlet-class>[PARA][PARA]
<init-param>[PARA] <param-name>log4j-init-file</param-name>[PARA]
<param-value>WEB-INF/classes/log4j.lcf</param-value>[PARA]
</init-param>[PARA][PARA] <load-on-startup>1</load-on-startup>[PARA]
</servlet>
Writing an initialization servlet is the most flexible way for initializing
log4j. There are no constraints on the code you can place in the init()
method of the servlet.

Objet : Log4J in EJBs
Hi-
I want to use Log4J in my EJBs.
The guidance I've been getting is that EJBs should not access system files
(e.g. log4j.properties).
Is there a recommended mechanism for configuring the LogFactory for EJBs?
Thanks,
ivan.
