Java Web Maven Project on tomcat 8 root path. How?

I have tried to put my application on the root path of the tomcat, I mean..

This is what I have now: http://ift.tt/1N8mPxx

But I need to get this-> http://ift.tt/tv1JJF

I already tried a lot of things I found on the web, but nothing worked.

I found many ways to do this, but nothing works.

What should I do on tomcat 8 ? Should I do something on the project ? any setting on the pom.xml or web.xml ?

Tks guys!!
