--- Comment #3 from Violeta Georgieva <vi...@apache.org> ---
Hi,

I tried the following:
- Configured log4j to output Tomcat's internal logging as described here [1]
- Deleted the content of the logging.properties
- Started Tomcat with security manager and -Djava.security.debug=all

The error that I received was:

access: access denied (java.io.FilePermission \C:\tc7.0.x\output\build\lib\
log4j.properties read)

Then I added the following to the catalina.policy:

grant codeBase "file:${catalina.home}/bin/tomcat-juli.jar" {
        ...
        permission java.io.FilePermission
        
"${catalina.base}${file.separator}lib${file.separator}log4j.properties",
"read";
        ...

Then I restarted Tomcat and everything was OK.


I cannot reproduce the exception.
