Answer 1

I did the following steps and the error removed.
1. Delete existing tomcat from the eclipse Server tab and remove existing tomcat directory
2. Provide new copy of tomcat in Server tab > add new server
3. Double click on tomcat from server tab
4. In tomcat overview tab, in Server Option
a. unselect > Select modules without publishing
b. unselect > Publish modules contexts to separate XML files
5. Save tomcat changes
6. Add project to tomcat
7. Publish
8. Start / Debug

Answer 2

I was also facing the same exception. In my case problem was, lib folder under WEB-INF was removed by me by mistake and I started to place custom jars in project main folder and referenced from there in the build path.
After spending a lot of time I realized this mistake and just corrected the directory structure and created lib folder under WEB-INF and placed custom jars in it and referenced from there. It started to work.

Please check same .java file exits in another package, if exits then delete this .java file to solve this type problem. (Eclipse IDE)
