I am trying to install kie-server for apache-tomcat-8.5.20. Tomcat is running but kie-workbench is not getting started. It throws the following error:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I have placed kie-server-6.3.0.Final-webc.war(which I have renamed to kie-server.war) in C:\apache-tomcat-8.5.20\webapps folder. The error occurred in deploying this web application archive. Any suggestion is welcome in regard to find the possible solution.
I downgraded the version of web application archive from kie-server-6.3.0.Final-webc.war to kie-server-6.2.0.Final-webc.war, as mentioned in 19.2.1.1 section of official documentation at https://docs.jboss.org/drools/release/6.2.0.Final/drools-docs/html/ch19.html#d0e19118 and the previous stack trace, is not occurring anymore.
