log4j in Tomcat 8.5

[George Stanchev <Gs...@serena.com>]

Hi,

I am transitioning from Tomcat 7.0 to Tomcat 8.5 and I was wondering what do I need to do to use log4j in 8.5. Reading this bug [1], it states that the support for the for log4j has been dropped since it is EOLed. Now, there is a comment on this issue from Mark that says that it is applied against version 9, but this bug was referenced from the changelog for 8.5 [2] that states:

<quote>
Correct a regression in the fix for 58588 that removed the entire org.apache.juli package from the embedded JARs rendering them unusable. (markt)
</quote>

which implies it has been applied to 8.5. So my question is, can I make Tomcat 8.5 use log4j?

George

log4j - no

log4j2 - yes

You'll need to use the standard log4j2 mechanism to capture 
java.util.logging output and redirect it.
