/**
* The <code>Action</code> annotation allows explicit association of a
* WS-Addressing <code>Action</code> message addressing property with
* <code>input</code>, <code>output</code>, and
* <code>fault</code> messages of the mapped WSDL operation.
* <p>
* 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</code> attribute on the WSDL <code>input</code>,
* <code>output</code> and <code>fault</code> messages of the WSDL <code>operation</code>
* is based upon which attributes of the <code>Action</code> annotation have been specified.
* For the exact computation of <code>wsam:Action</code> values for the messages, refer
* to the algorithm in the JAX-WS specification.
* <p>
* <b>Example 1</b>: Specify explicit values for <code>Action</code> message addressing property
* for <code>input</code> and <code>output</code> messages.
*
* <pre>
* &#64;WebService(targetNamespace="http://example.com/numbers")
* public class AddNumbersImpl {
* <b>&#64;Action(
* input="http://example.com/inputAction",
* output="http://example.com/outputAction")</b>
* public int addNumbers(int number1, int number2) {
* return number1 + number2;
* }
* }
* </pre>
*
* The generated WSDL looks like:
* <pre>
* &lt;definitions targetNamespace="http://example.com/numbers" ...>
* ...
* &lt;portType name="AddNumbersPortType">
* &lt;operation name="AddNumbers">
* &lt;input message="tns:AddNumbersInput" name="foo"
* <b>wsam:Action="http://example.com/inputAction"</b>/>
* &lt;output message="tns:AddNumbersOutput" name="bar"
* <b>wsam:Action="http://example.com/outputAction"</b>/>
* &lt;/operation>
* &lt;/portType>
* ...
* &lt;/definitions>
* </pre>
*
* <p>
* <b>Example 2</b>: Specify explicit value for <code>Action</code> message addressing property
* for only the <code>input</code> message. The <code>wsam:Action</code> values for the
* WSDL <code>output</code> message are computed using the algorithm in the JAX-WS specification.
*
* <pre>
* &#64;WebService(targetNamespace="http://example.com/numbers")
* public class AddNumbersImpl {
* <b>&#64;Action(input="http://example.com/inputAction")</b>
* public int addNumbers(int number1, int number2) {
* return number1 + number2;
* }
* }
* </pre>
*
* The generated WSDL looks like:
* <pre>
* &lt;definitions targetNamespace="http://example.com/numbers" ...>
* ...
* &lt;portType name="AddNumbersPortType">
* &lt;operation name="AddNumbers">
* &lt;input message="tns:AddNumbersInput" name="foo"
* <b>wsam:Action="http://example.com/inputAction"</b> />
* &lt;output message="tns:AddNumbersOutput" name="bar"
* <b>wsam:Action="http://example.com/numbers/AddNumbersPortType/AddNumbersResponse"</b>/>
* &lt;/operation>
* &lt;/portType>
* ...
* &lt;/definitions>
* </pre>
*
* It is legitimate to specify an explicit value for <code>Action</code> message addressing property for
* <code>output</code> message only. In this case, <code>wsam:Action</code> value for the
* WSDL <code>input</code> message is computed using the algorithm in the JAX-WS specification.
*
* <p>
* <b>Example 3</b>: See {@link FaultAction} annotation for an example of
* how to specify an explicit value for <code>Action</code> message addressing property for the
* <code>fault</code> message.
*
* @see FaultAction
*
* @since JAX-WS 2.1
