Answer 1

You should try deleting existing deployed war from webapps of tomcat and try redeploying a fresh war. It seems your any of the existing application has same packaging details which are conflicting with your new project.

Clear those wars ( and there directories ) from webapps which are not required.

Answer 2

had the same problem with me. I just deleted(not un-installed) the old tomcat and installed new tomcat with same version on the same directory as before. Worked perfectly for me.
