. The name CXF derives from combining the "Celtix" and "XFire" project names.

The CXF key design considerations include:

Clean separation of front-ends
Front-end and back-end
Front end and back end are generalized terms that refer to the initial and the end stages of a process. The front end is responsible for collecting input in various forms from the user and processing it to conform to a specification the back end can use...
