[slf4j-user] blog entry on JCL

[Ceki Gülcü]

Matt,

The NoClassDefFoundError on "org/slf4j/LoggerFactory" indicates that you 
are missing an SLF4J binding. Do you have an SLF4J binding? On top of 
slf4j-api.jar, jcl-over-slf4j.jar, you also need any one of 
slf4j-nop.jar/slf4j-simple.jar/slf4j-log4j12.jar files.

HTH.
