Migrating an application from JBoss AS to Tomcat

Question

I am trying to migrate a Spring based web application from JBoss to Tomcat. The web application uses Spring Framework, JPA, JSF, with oracle being the back end.

What are the things which I have to focus on when migrating this application?

Answer 1

JBoss AS is something which should provide you an environment where the libraries and frameworks are already integrated, configured, tested and tuned.

If you're really going to give that up, you'll have to focus on all of that:

Adding all libraries, syncing their conflicting versions, configure them separatedly, weave them using some IoC framework, etc etc.

I know this answer is 2 years old, but I'd strongly recommend to look at JBoss AS 7 / JBoss EAP 6, which is way way easier to configure and maintain than 5, takes lot less memory, boots in few seconds. I migrated my apps from Tomcat to JBoss AS 7, now using WildFly 10.1.0.
