Title: Comparison
Apache OpenEJB and Apache TomEE are born from the same project and community. They differ in two major ways, only one of them technical:
- TomEE incorporates two additional projects; Tomcat and MyFaces
- TomEE, as a name, more easily implies the breadth of technologies included
Effectively, TomEE is a superset of OpenEJB. They share the same code and TomEE grew out of OpenEJB.
Note: this table is for TomEE 1.x, TomEE 7 comments are under it.
