Metro is a high-performance, extensible, easy-to-use web service stack and is a part of the GlassFish Application Server. Metro incorporates JAXB 2.x RI and JAX-WS 2.x Web services standards, along with other XML-related Java standards. Metro also includes added nonstandard components to support both basic JAX-WS service definition and usage and a variety of WS-* extensions to SOAP message exchange.[2]
Metro augments the JAX-WS environment with advanced features such as trusted, end-to-end security; optimized transport (MTOM, Fast Infoset), reliable messaging, and transactional behavior for SOAP web services.
