The JAX-WS APIs include a set of annotations which allow you to build services using annotated classes. These services are based on a single class which contains a set of operations.

Here's a simple example:

public class Hello {
   public String sayHi(String name) {
      return "Hello " + name;

JAX-WS includes many more annotations as well such as:

  • @WebMethod - allows you to customize the operation name, exclude the operation from inclusion in the service, etc

  • @WebParam - allows you to customize a parameter's name, namespace, direction (IN or OUT), etc

  • @WebResult - allows you to customize the return value of the web service call

Data is marshalled from XML to Java and vice versa via the JAXB data-binding.

Services are publish via one of two means:

  • The JAX-WS standard Endpoint APIs

  • CXF's XML configuration format - i.e. <jaxws:endpoint ... />
