404 Error When Trying to Access App

[LibraryIT]

After some thinking we've decided to use Tomcat to run the order import tool at Skidmore, mostly because the college's other Java apps all run on Tomcat. We can upload the .WAR file and restart the service, resulting in the app starting correctly (according to the log files). However when we try to navigate to it's context, in a browser the result is a 404 error. Are there extra steps needed to get the app working with Tomcat or does it only work with Jetty?
