/**
* The {@code Action} annotation allows explicit association of a
* WS-Addressing {@code Action} message addressing property with
* {@code input}, {@code output}, and
* {@code fault} messages of the mapped WSDL operation.
*
* This annotation can be specified on each method of a service endpoint interface.
* For such a method, the mapped operation in the generated WSDL's
* {@code wsam:Action} attribute on the WSDL {@code input},
* {@code output} and {@code fault} messages of the WSDL {@code operation}
* is based upon which attributes of the {@code Action} annotation have been specified.
* For the exact computation of {@code wsam:Action} values for the messages, refer
* to the algorithm in the JAX-WS specification.
*
* Example 1: Specify explicit values for {@code Action} message addressing property
* for {@code input} and {@code output} messages.
*
*
* {@literal @}WebService(targetNamespace="http://example.com/numbers")
* public class AddNumbersImpl {
* {@literal @}Action(
* input="http://example.com/inputAction",
* output="http://example.com/outputAction")
* public int addNumbers(int number1, int number2) {
* return number1 + number2;
* }
* }
*
*
* The generated WSDL looks like:
* {@code
*
* ...
*
*
* wsam:Action="http://example.com/inputAction"/>
*
*
* ...
*
* }
*
*
*
* Example 2: Specify explicit value for {@code Action} message addressing property
* for only the {@code input} message. The {@code wsam:Action} values for the
* WSDL {@code output} message are computed using the algorithm in the JAX-WS specification.
*
*
* {@literal @}WebService(targetNamespace="http://example.com/numbers")
* public class AddNumbersImpl {
* {@literal @}Action(input="http://example.com/inputAction")
* public int addNumbers(int number1, int number2) {
* return number1 + number2;
* }
* }
*
*
* The generated WSDL looks like:
* {@code
*
* ...
*
*
* wsam:Action="http://example.com/inputAction"/>
*
*
* ...
*
* }
*
* It is legitimate to specify an explicit value for {@code Action} message addressing property for
* {@code output} message only. In this case, {@code wsam:Action} value for the
* WSDL {@code input} message is computed using the algorithm in the JAX-WS specification.
*
*
* Example 3: See {@link FaultAction} annotation for an example of
* how to specify an explicit value for {@code Action} message addressing property for the
* {@code fault} message.
*
* @see FaultAction
*
* @since 1.6, JAX-WS 2.1
