Java Web Services Technologies: Java Api For Xml Web Services (Jax Ws) And Java Api For Res Tful Web Services (Jax Rs)

1547 words - 7 pages

Web services are applications components that communicate using open XML-based standards and transport protocols to exchange data with calling clients. They are self-containing and self-describing and can be discovered using the Universal Description, Discovery, and Integration (UDDI). They can also be used by other applications and can be published, located, and invoked across the Web. HTTP and XML are the basis for Web services. The Java platform provides the XML and RESTful APIs and tools needed to quickly design, develop, test, and deploy web services and clients that fully interoperate with other web services and clients running on Java-based or non-Java-based platforms. REST (Representational State Transfer) is an architectural style which is based on web-standards and the HTTP protocol. The RESTFul web services are based on HTTP methods (POST, GET, PUT, DELETE). XML Web Services (JAX-WS) is used to develop Web services and is a part of the Java development Kit (JDK). JAX-WS technology is used with other technologies, either from the core group or more enhanced Web services. Security in web services is important as in any other communication technology. This due to the fact that businesses are willingly to perform transactions over the internet and do not require human presence as well. There are boundaries of interaction between communicating entities. This means that all security requirements such as authentication, access control, non-repudiation, data integrity, and privacy must be addressed by the underlying security technology: web services. This research paper will give details about the definition of Java web services, different types of web services, factors to consider when choose a specific type of web services and how to secure the Java web services.
According to Oracle, "Web services are Web based applications that use open, XML-based standards and transport protocols to exchange data with clients. Web services are developed using Java Technology APIs and tools provided by an integrated Web Services Stack called Metro. The Metro stack consisting of JAX-WS, JAXB, and WSIT, enable you to create and deploy secure, reliable, transactional, interoperable Web services and clients. The Metro stack is part of Project Metro and as part of GlassFish, Java Platform, Enterprise Edition (Java EE), and partially in Java platform, Standard Edition (Java SE). GlassFish and Java EE also support the legacy JAX-RPC APIs." In today's technologically driven society, Web Services are quickly becoming the most pertinent technologies in computer software, e-business and communication industries. Web Service technologies continue to restructure and enhance the way that companies conduct business and disperse information in our society. Web Services continually improve business productivity by supplying information from a vast array of resources. RESTful services relies of HTTP protocol and methods (GET, POST, PUT, DELETE) to interchange messages in...
