Apache CXF是一个开源的，全功能的，容易使用的Web服务框架。CXF是两个项目的结合：由IONA技术公司（现在是Progress的一部分）开发的Celtix和由Codehaus主持的团队开发的XFire，合并是由人们在Apache软件基金会共同完成的。CXF的名字来源于"Celtix"和"XFire"的首字母。

CXF的关键的设计考虑因素包括：

在面向服务的架构（SOA）基础设施项目中，CXF通常和Apache ServiceMix，Apache Camel以及Apache ActiveMQ一起使用。

Apache CXF is an open-source, fully featured Web services framework. It originated as the combination of two open-source projects: Celtix developed by IONA Technologies (acquired by Progress Software in 2008) and XFire developed by a team hosted at Codehaus. These two projects were combined by people working together at the Apache Software Foundation and the new name CXF was derived by combining "Celtix" and "XFire".
