EJB, log4j, and access denied to log4.properties

Hi,

I am tried to get to log4j to work with Sun's App Server, 1.3.1. The java
machine that I am running is 1.4.2_03. Linux is red had's linux 9.2.

I am getting an error :

.. java.security.AccessControlException: access denied (java.io.FilePermission /tmp/log4j.properties read).



The code that I have in my entity bean is placed in the ejbCreate():

PropertyConfigurator.configure ("/tmp/log4j.properties").


Additionally, I've modied the java machines' java.policy file in the home
directory of the java installation. Via the policytool I've the added line:

grant codeBase "file:/tmp/*" {
permission java.security.AllPermission;
};

Any help is appreciated or if you have a differnt method to allow the App Server access to the log4.properties. I've also tried to place the log4.properties file on the class path of the J2EE server. That did not work with but it gave me a different error:



log4j:WARN No Appenders could be found for logger...

If you got it working, I do appreciate your help.

Thanks
Nick

I may answered my question. I've found the following comment on another conversation thread. According to this comment, what I am trying to do can not be done..Here is the comment that I've found:

*****************

EJB spec explicitly indicates that (section 24.1.2 Programming restrictions):

quote:
An enterprise bean must not use the java.io package to attempt to access files and directories in the file system.
The file system APIs are not well-suited for business components to access data. Business components should use a resource manager API, such as JDBC, to store data.
 
It is sorta covered in the JavaRanch Style Guide.
