Tomcat Not starting up> java.lang.ClassNotFoundException: org.apache.catalina.startup.Catalina

Question

I am unable to start the tomcat 5.5 server due to following error message in the stderr.log. Can someone please help me, it is kind of emergency. Thanks in advance.

Answer 1

I was facing the same issue. Then I noticed that I have accidentally deleted lib folder from tomcat directory. The issue got resolved as lib folder back in place.
