[logback-user] Simplest Java sample; Simplest logback.xml; what no logfile

[Abraham Lin]

The SLF4J library is just an API that expects an implementation (not
necessarily logback) to be bound at runtime. See the documentation:
http://www.slf4j.org/manual.html. It also looks like you've provided the
JDK logging binding, so your code is using that instead of the fallback NOP
logger.

Your program has no dependencies on logback APIs, so there's no reason why
it wouldn't work.
