Apache CXF is an open source software project developing a Web services framework. It originated as the combination of Celtix developed by IONA Technologies and XFire developed by a team hosted at the now defunct host CodeHaus in 2006. These two projects were combined at the Apache Software Foundation. The name "CXF" was derived by combining "Celtix" and "XFire".[1]
