             Summary: Class load error with slf4j-api on Tomcat8
                 Key: DROOLS-908
                 URL: https://issues.jboss.org/browse/DROOLS-908
             Project: Drools
          Issue Type: Bug
          Components: kie server
    Affects Versions: 6.3.0.CR2
         Environment: apache-tomcat-8.0.26

            Reporter: Timo Riikonen
            Assignee: Edson Tirelli


Installation instructions request that slf4j-api JAR file is copied to Tomcats lib directory. And correctly also as the Tomcat won't start if it is not in there.
But then this API conflicts with the same API in kie-server-6.3.0.CR2-ee7.

I did a quick fix that seemed to solve this:

# Removed kie-server WAR file from tomcat webapps directory, so that it won't undo the next step.
# Deleted the problem file webapps/kie-server-6.3.0.CR2-ee7/WEB-INF/lib/slf4j-api-1.7.2.jar

I considered removing the jar file from Drools project, but that is likely to cause other errors, so I decided to leave this to the experts (= you guys).
