/**
* The Action annotation allows explicit association of a
* WS-Addressing Action message addressing property with
* input, output, and
* 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
* wsam:Action attribute on the WSDL input,
* output and fault messages of the WSDL operation
* is based upon which attributes of the Action annotation have been specified.
* For the exact computation of wsam:Action values for the messages, refer
* to the algorithm in the JAX-WS specification.
*
* Example 1: Specify explicit values for Action message addressing property
* for input and output messages.
*
*
* @WebService(targetNamespace="http://example.com/numbers")
* public class AddNumbersImpl {
* @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:
*
* <definitions targetNamespace="http://example.com/numbers" ...>
* ...
* <portType name="AddNumbersPortType">
* <operation name="AddNumbers">
* <input message="tns:AddNumbersInput" name="foo"
* wsam:Action="http://example.com/inputAction"/>
* <output message="tns:AddNumbersOutput" name="bar"
* wsam:Action="http://example.com/outputAction"/>
* </operation>
* </portType>
* ...
* </definitions>
*
*
*
* Example 2: Specify explicit value for Action message addressing property
* for only the input message. The wsam:Action values for the
* WSDL output message are computed using the algorithm in the JAX-WS specification.
*
*
* @WebService(targetNamespace="http://example.com/numbers")
* public class AddNumbersImpl {
* @Action(input="http://example.com/inputAction")
* public int addNumbers(int number1, int number2) {
* return number1 + number2;
* }
* }
*
*
* The generated WSDL looks like:
*
* <definitions targetNamespace="http://example.com/numbers" ...>
* ...
* <portType name="AddNumbersPortType">
* <operation name="AddNumbers">
* <input message="tns:AddNumbersInput" name="foo"
* wsam:Action="http://example.com/inputAction" />
* <output message="tns:AddNumbersOutput" name="bar"
* wsam:Action="http://example.com/numbers/AddNumbersPortType/AddNumbersResponse"/>
* </operation>
* </portType>
* ...
* </definitions>
*
*
* It is legitimate to specify an explicit value for Action message addressing property for
* output message only. In this case, wsam:Action value for the
* WSDL 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 Action message addressing property for the
* fault message.
*
* @see FaultAction
*
* @since JAX-WS 2.1
