我执行了以下步骤并删除了错误.

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
