Question

We\'re building new systen using slf4j as logging facade. When deploying on newly Weblogic 12c, we found this error on console log:

SLF4J: Class path contain         


        

Answer 1

For WAR file you should use prefer-application-packages in weblogic.xml like described in this and this posts.

In your case it will be something like

    
        
            org.slf4j
