Because in websphere_stderr.log file, there is a line log4j:ERROR No appenders could be found for category (com.company.ejb.myBean). log4j:ERROR Please initialize the log4j system properly. However, in websphere_stdout.log file, looks like websphere does include log4j.jar in its classpath. Java Home = D:\IBM\AppServer\java\jre Classpath = D:/IBM/AppServer/properties;D:/IBM/AppServer/lib/bootstrap.jar;d:/IBM/AppSer ver/lib/log4j.jar Thanks.

Section EJB.18.1.2 contains a list of programming restrictions for bean providers. In that section it states "An enterprise bean must not use the java.io package to attempt to access files and directories in the file system." I'm not sure if Webshpere allows violation of the specification or not. There are a couple of ways to work around this, however. 1. You can use the JDBC appender to write log information to a database. Since JDBC is part of the J2EE specification this is fully complient. 2. You can create a logging service that runs in a separate process and utilize JMS to send messages from your EJB beans to the logging service.

Now my problem is my Log4J works fine with any classes except EJB beans class. Any idea about how to configure WebSphere 4.0? I run my J2EE app within WebSphere for a while. Then I examine my log output file, it has all necessary output from any java classes except EJB beans. I vaguely remember awhile back somebody mentioned that Log4J violates EJB spec. Do I need to configure my WebSphere 4.0 to allow access to the file (the output is file).
