Java API for XML Web Services

Java API for XML Web Services
From Wikipedia, the free encyclopedia


The Java API for XML Web Services (JAX-WS) is a Java programming language API for creating web services. It is part of the Java EE platform from Sun Microsystems. Like the other Java EE APIs, JAX-WS uses annotations, introduced in Java SE 5, to simplify the development and deployment of web service clients and endpoints.

The Reference Implementation of JAX-WS is developed as an open source project and is part of project GlassFish, an open source Java EE application server. It is called JAX-WS RI (For Reference Implementation) and is said to be production quality implementation (contrary to the former Reference Implementation being a proof of concept). This Reference Implementation is now part of the Metro distribution[1].

JAX-WS also is one of the foundations of WSIT.

[edit] Name change

JAX-WS 2.0 replaced the JAX-RPC API in Java Platform, Enterprise Edition 5. The name change reflected the move away from RPC-style and toward document-style web services.
