Servlet running on Tomcat in Eclipse but not displaying on Ubuntu Server Tomcat - eclipse

Question

I have a servlet as follows that is running perfectly on my Eclipse tomcat. When I upload it to the webapps folder and restart my tomcat on my Ubuntu server, the URL for it(/ServerAPP/Login) won't load, though the tomcat root page does fine. If anyone has any idea why this is happening, I would greatly appreciate it. I'm fairly new to Ubuntu and the inner workings of Tomcat so I could have missed anything.
I can give more information on request, I'm just not sure how much is needed, or if there's something simple and stupid I'm not thinking about.

Answer 1

So I ended up figuring it out, and I thought it might help others to know.
Reason:
Apparently, my tomcat on ubuntu was only java 6, while my eclipse was targeting java 7.
Fix:
I went to the project properties and changed the target(which made eclipse mad), but then recompiled it and put it on the tomcat on ubuntu, and it works fine.
Thanks to the people who tried to help me.
