Apache TomEE is a Java EE 6 Web Profile certified application server built on top of Tomcat. It includes Apache components like MyFaces, OpenWebBeans, OpenEJB, OpenJPA, and Bean Validation. The entire Web Profile is only 24MB in size and has a small memory footprint. It aims to prove that a certified Java EE stack can be lightweight and agile. Future goals include further optimizations to reduce size and improve performance.
