Spring boot app won't start on Tomcat Server

Question

I am trying to deploy a spring boot application as a WAR to a tomcat server. I can build and deploy the war to the tomcat server just fine. When I start the server though my spring application never runs. The server starts up just fine. I have done everything Spring says to do here,

http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file

My project has its own custom Parent POM and consists of 2 modules.

I have read several other similar threads and as far as I can tell I have everything set up properly but clearly something is wrong. Any help would be much appreciated.

THank You!

Check your catalina.out and localhost log file in tomcat logs directory. May be it log any config error. — Sangam Belose
For starters fix your dependencies, you are mixing Spring Boot 1.3.3, 1.3.0 and 1.5.0 jars. Next to that you have an old, non-compatible, version of spring-context-support added (remove that dependency as that is already pulled in elsewhere) and replace the mail dependency with spring-boot-starter-mail. I also strongly suggest to have your parent extend the sprig boot parent then also remove the war plugin (as you don't need that anymore). — M. Deinum
I am using the STS default pivotal tc server. I am just using the Add/Remove option when right clicking the server to deploy the war. Deinum I have edited my poms above, still the server starts without deploying the war. — Karaja

Remember to refresh the application once deployed in Tomcat. It may be working well and only a refresh is needed.
