open-in-new
<p>Jakarta Web Services Metadata (JWS; formerly Web Services Metadata for Java platform and Java Web Services), as a part of <a href="/facts/Jakarta_XML_Web_Services/xcIMaPgp">Jakarta XML Web Services</a> (JAX-WS), is a Java programming language specification (JSR-181) primarily used to standardize the development of <a href="/facts/Web_service/qxrwqB3D">web service</a> interfaces for the <a href="/facts/Jakarta_EE/7AAStd35">Jakarta EE</a> platform. </p><p>Using annotations from the JSR 181, you can annotate a Web service implementation class or a Web service interface. It enables developers to create portable Java Web Services from a simple <a href="/facts/Plain_old_Java_object/sTUnd6MN">plain old Java object</a> (POJO) class by adding annotations, and also helps in generating a Web service with a wizard or by publishing the service on to a server. </p><p>Some of the annotations specified by this JSR are: </p> <ul><li>@WebService</li> <li>@WebMethod</li> <li>@Oneway</li> <li>@WebParam</li> <li>@WebResult</li> <li>@HandlerChain</li> <li>@SOAPBinding</li></ul> <p>Put simply, <a href="http://jcp.org/en/jsr/detail?id=181">JSR 181</a> is a specification to define standard and portable web services. It offers the following benefits: </p> <ul><li>Provide a simplified model for developing web services</li> <li>Abstract the implementation details</li> <li>Achieve robustness, easy maintenance, and high interoperability</li></ul> <p>Version is 2.1 was released on December 15, 2009. </p>
