Dependencies for displaytag library

Question

I am integrating the displaytag library into my web application. I have used the library at my work, but what I am currently building does not have it currently. When I went to review the dependencies for installation of the library, I noticed that it had the following listed...

commons-logging
commons-lang
commons-collections
commons-beanutils
log4j

I believe that I have provided all of the commons dependencies that it needs, but I noticed that it also has log4j. I am not currently using log4j as my logging, so I am curious if it will in fact not work if I dont have log4j set up, or if it will be fine and just needs it available.

It doesn't really mention in the installation documentation provided at

Display Tag Installation

Answer 1

This link seems to indicate that log4j is Optional (at least for version 1.2).

The same page mentions that slf4j is Not optional, indicating that the library has been coded using slf4j. If so, instead of log4j, any other logging provider can be substituted.
