Implementing High Performance Web Services Using JAX-WS 2.0

Service-Oriented Architecture (SOA) allows businesses to enable legacy systems and new software products as a service to a wider audience by way of the Internet. Web services technology is the cornerstone of SOA implementation, which involves complex business transactions between various business entities. XML processing, the core component of web services technology, involves SOAP processing, XML binding, and XML parsing. Understanding various traits of the Web Services Description Language (WSDL) is important for gaining better performance and scalability of web services. This paper shows how to implement high performance web services using the Java API for XML Web Services (JAX-WS) 2.0 and provides feature and performance comparisons with the Java API for XML-Based RPC (JAX-RPC) 1.1.
