回答1:

Eclipse and Tomcat are both in confusion. I'd suggest to clean and rebuild all.

1. Remove project from Tomcat (rightclick Tomcat, Add/Remove project, remove project)
2. Close project in Eclipse (rightclick project, Close)
3. Clean Tomcat (rightclick Tomcat, Clean)
4. Reopen project in Eclipse (rightclick project, Open)
5. Clean project in Eclipse (Project > Clean... > Clean selected projects below, select project)
6. Add project to Tomcat (rightclick Tomcat, Add/Remove projects, add project)
7. Start Tomcat (rightclick Tomcat, Start).
