What is the recommended application layer to use in 3 tier architecture using Java?

Question

So my situation is that I am trying to figure out the best architecture for my system to use, current my project consists of a frontend using the Android SDK, and a MySQL database what I need my application layer to do is make requests to and from a REST api, and to manage a login system with the database.

I've been told that Apache tomcat with a java servlet might be a good approach but I'd like to ask here to see if you guys have any ideas.

Answer 1

This really depends on your requirement. For not so complicated business logic , tomcat which is only a web server may suffice. However , if you have complex business logic , distributed architecture , clustering etc. which may need to support EJB, JMS etc then tomcat will not be sufficient but you will need app server like JBoss , Weblogic etc.
