I have the following files in the WEB-INF/lib. But still get the error. slf4j-api-1.7.3.jar,logback-classic-1.0.10.jar,logback-core-1.0.10.jar On Tue, Mar 19, 2013 at 10:49 AM, Ceki Gülcü <ceki@qos.ch> wrote:
The error indicates that com.zreflect.emyed.whiteboard.**pubsub.EventLoggerAsync class is expecting a ch.qos.logback.classic.**LoggerContext, instead it obtains a org.slf4j.helpers.**NOPLoggerFactory. This usually occurs when some code tries to cast the return value of org.slf4j.LoggerFactory.**getILoggerFactory and slf4j is bound to the NOP implementation because no slf4j binding was available on the class path. This is usually accompanied with an error message. See:
