Apache CXF is an open-source Java services framework governed by the Apache Software Foundation that helps build and develop web services using JAX-WS (SOAP) and JAX-RS (REST) frontend APIs. It supports contract-first (WSDL) and code-first development, full WS-* standards (WS-Security, WS-ReliableMessaging, WS-Addressing, WS-Policy), multiple transports (HTTP, JMS), and integrates with Spring Framework, OSGi/ServiceMix, and major Java EE servers.
