TomE vs Apache Geronimo

[rosemadder]

Please explain the difference between TomEE and Apache Geronimo.

[Pearlaqua]

Both are the implementation of J2EE, a set of apps based on Tomcat. Differences are in the set of components used and the fact that Geronimo is more dead than alive (the last release in 2013) and that TomEE is actively developing, maintained and the J2EE7 approach.
