Answer 1

Eclipse and Tomcat are both in confusion. I'd suggest to clean and rebuild all.
Remove project from Tomcat (rightclick Tomcat, Add/Remove project, remove project)
Close project in Eclipse (rightclick project, Close)
Clean Tomcat (rightclick Tomcat, Clean)
Reopen project in Eclipse (rightclick project, Open)
Clean project in Eclipse (Project > Clean... > Clean selected projects below, select project)
Add project to Tomcat (rightclick Tomcat, Add/Remove projects, add project)
Start Tomcat (rightclick Tomcat, Start).
