You have slf4j-log4j12.jar, logback-classic.jar and slf4j-simple.jar on your classpath - that&#39;s three separate SLF4J implementations.  You should have only one (logback-classic, presumably).  It&#39;s initialising SLF4J Simple, so when you retrieve the SLF4J LoggerFactory it&#39;s returning an org.slf4j.impl.SimpleLoggerFactory which you then try and cast to ch.qos.lobgack.LoggerFactory, which naturally fails.<br>

<br>
Take slf4j-log4j12.jar and slf4j-simple.jar off your classpath - if you are trying to redirect log4j to slf4j then you need log4j-over-slf4j.jar, not slf4j-log4j12.jar which instead uses log4j as the slf4j implementation.<br>
