If there is a Java based application that is running on your server, there is a good chance that it is using log4j for logging. If the application uses local log4j libraries then you can search for the presence of log4j on the server. If you are running a GNU/Linux system you could do something like the following script as a broad search across files.
The Log4j 2 API supports logging any Char. Sequence if you want to log text, but also supports logging any Object as is. It is the responsibility of the logging implementation to handle this object, and we consider it a design mistake to limit applications to logging Strings.
How do I use Log4j with SLF4J?
You can use the log4j-to-slf4j adapter jar when your application calls the Log4j 2 API and you want to route logging calls to a SLF4J implementation. Some of the Log4j components have features with optional dependencies. The component page will have more detail.
For example, the log4j-core component page has an outline of which log4j-core features have external dependencies. How do I exclude conflicting dependencies? There are several scenarios where you may end up with conflicting dependencies, especially transitively included ones.
