Enhancements in Java SE 6 for Web Services: JAX-WS and Beyond

Explore the significant advancements in Java SE 6 regarding web services, particularly the transition from JAX-RPC to JAX-WS 2.0. This article delves into the redefined policies by SUN for supporting web service technologies, including remote procedure calls (RPC), XML-RPC, and SOAP. Learn how the integration of JAX-WS and JAXB simplifies service-oriented architecture, providing support for service discovery with UDDI and WSDL. This comprehensive overview helps developers grasp the evolution of web services in Java SE 6, featuring a testing-friendly small web server and improved performance standards.
