Another thing that may be missing in Markus's setup is a logger implementation binding. SLF4J is just a proxy to another logger after all. So if you imported "slf4j-simple", remove that import, and import the actual logger impl. E.g. Logback (John's example is based on Log4J - yet another popular logger):
<dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> </dependency> SLF4J discovers it automatically and you'll be able to control log levels per Logback documentation [1] (or Log4J if you decided to use that).
