The philosophy - Keep it Tight, Keep it Simple
There's a definite "less is more" philosophy in Apache TomEE. We're not here to create an ultra flexible, super powerful, infinitely composable, be anything to anyone platform. We're here to
- deliver Java EE 6 Web Profile in the simplest way possible.
- make the developers life easier
If you were to imagine taking a plain Tomcat install and integrating the missing components in the most direct and to-the-point style possible, you'd end up with TomEE. The result speaks for itself:
- Runs without any additional memory requirements
- Compatible with Tomcat-aware tools
- Compatible with Tomcat-tested apps
Focuses
Some core focuses guide the integration:
- Don't mess with Tomcat
- Keep it simple
- Avoid architecture overhead
- Allow users to get the job done
History
In Apache TomEE's previous life, it was simply known as the OpenEJB+Tomcat integration. That description was always quite misleading. For one, there's incredible benefit even if EJB is never used.
Quite simply, EJB as a technology integrates with the most number of specs than any other spec. It touches JMS, Web Services, Connectors, Servlets (EJB Web Services are still driven by Servlets!), JPA, JDBC, Transactions, Security. Integrating with all these technologies takes time and expertise and in the end has very little to do with EJB specifically. To apply this all to Tomcat and leverage it all from a simple Servlet is a natural extension and the reason most app servers started out as EJB servers.
Whereas most app servers pluck Tomcat out of its environment, Apache OpenEJB has always existed as an embeddable container focused on being as tiny and invisible as possible. The natural extension of this is to embed the "EE" into Tomcat, rather than the other way around.
But in the end, it is not about EJB. It's about the other guys: ActiveMQ, CXF, MyFaces, OpenJPA, OpenWebBeans, and of course Tomcat! So out with OpenEJB+Tomcat and in with Apache TomEE!
