After searching a lot I always find the same answer about permissions, but it is no use in this situation.

It works when I use the absolute path.

Plase, help!

Thanks!

EDIT:

I'm using tomcat 6.0

-bash-3.00$ /opt/tomcat/instances/tomcat-8080/bin/startupDev.sh version
Using CATALINA_BASE:   /opt/tomcat/instances/tomcat-8080
Using CATALINA_HOME:   /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/instances/tomcat-8080/temp
Using JRE_HOME:       /usr/java

Answer 1

${catalina.base} is resolving to an empty string. Try using another environment variable or absolute path here:

<param name="File" value="${catalina.base}/logs/jump_page.log" />

Answer 2

Please try out the following to diagnose this issue further and report it back in your question. Telling us on which platform you are would help also.

Enable debug output

In your catalina.properties file (located in the conf folder of your Tomcat installation, or /etc/tomcat? for Linux), please append this property to enable log4j debugging output.

log4j.debug=true

This should give you more hints on what's going wrong.

Test the file path with static and complete path configuration

Also, while the catalina.base system property should be set in a Tomcat's environment, is this possible that log4j actually tries to access the /logs folder from the filesystem root? As in, the catalina.base system property would not be set or considered? What happens if you put a complete and static path in your configuration?
