org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]] - tomcat 8.5

Question

I am trying to get my tomcat 8.5 to start on my eclipse. Everytime I get this error.

I already tried the below fixes but nothing seems to work:

• Added log4j.jar to my classpath
• cleaned Tomcat Directory
• My JDK is 1.8
• My JRE is 1.8

Any idea what else to try?

Answer 1

I found my issue.
My lib folder was outside the WebContent folder...
I copied it inside WebContent/WEB-INF and everything is working now
