Which are the important annotations used in JAX WS API?

1. JAX-WS annotations

  • 1.1 @WebService. This JAX-WS annotation can be used in 2 ways.
  • 1.2 @SOAPBinding. Demonstration of @SOAPBinding JAX-WS annotation has already been shown in first program in 1.1.
  • 1.3 @WebMethod. @WebMethod JAX-WS annotation can be applied over a method only.
  • 1.4 @WebResult.
  • 1.5 @WebServiceClient.

What is targetNamespace in Web service?

targetNamespace is the logical namespace for information about this service. WSDL documents can import other WSDL documents, and setting targetNamespace to a unique value ensures that the namespaces do not clash. xmlns is the default namespace of the WSDL document, and it is set to http://schemas.xmlsoap.org/wsdl/ .

What is JAX-WS RI?

JAX-WS RI 2.3. 1 is a Web Services framework that provides tools and infrastructure to develop Web Services solutions for the end users and middleware developers. With JAX-WS RI 2.3. 1, clients and web services have a big advantage: the platform independence of the Java programming language.

What is the difference between Jax RS and JAX-WS?

Actually,JAX-WS represents both RESTful and SOAP based web services. One way to think about it is that JAX-RS specializes in RESTful, while JAX-WS allows you more flexibility to choose between either, while at the same time being (in some cases) more complicated to configure. Thank you for simple explanation.

What is Jersey and RESTEasy?

Introduction. Two frameworks have emerged to simplify the development of RESTful web services and applications in Java—Jersey and RESTEasy. These frameworks are two of the most popular implementations of the JAX-RS standard. Both frameworks provide a nice feature set that simplifies the development of REST APIs.
