Java API for XML Web Services (JAX-WS) is one of a set of Java technologies used to develop Web services. JAX-WS belongs to what Sun Microsystems calls the "core Web services" group. Like most of the core group, JAX-WS is typically used in conjunction with other technologies. Those other technologies may also come from the core Web services group (JAXB, for example), as well as from enhanced Web services (WSIT), secure Web services (WSIT, WS-Security), legacy Web services (JAX-RPC), and systems management services (WS-Management) groups.
JAX-WS is a fundamental technology for developing SOAP (Simple Object Access Protocol) and RESTful (Web services that use representational state transfer, or REST, tools) Java Web services, where JAX-WS is designed to take the place of the JAVA-RPC (Remote Procedure Call) interface in Web services and Web-based applications. JAX-WS is also used to build Web services and corresponding clients that communicate using XML to send messages or use remote procedure calls to exchange data between client and service provider.
