/**
* The <code>FaultAction</code> annotation is used inside an {@link Action}
* annotation to allow an explicit association of a WS-Addressing
* <code>Action</code> message addressing property with the <code>fault</code>
* messages of the WSDL operation mapped from the exception class.
* <p>
* The <code>wsam:Action</code> attribute value in the <code>fault</code>
* message in the generated WSDL operation mapped for <code>className</code>
* class is equal to the corresponding value in the <code>FaultAction</code>.
* For the exact computation of <code>wsam:Action</code> values for the
* fault 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 the <code>input</code>, <code>output</code> and <code>fault</code> message
* if the Java method throws only one service specific exception.
*
* <pre>
* &#64;WebService(targetNamespace="http://example.com/numbers")
* public class AddNumbersImpl {
* &#64;Action(
* fault = {
* <b>&#64;FaultAction(className=AddNumbersException.class, value="http://example.com/faultAction")</b>
* })
* public int addNumbers(int number1, int number2)
* throws AddNumbersException {
* 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;fault message="tns:AddNumbersException" name="AddNumbersException"
* <b>wsam:Action="http://example.com/faultAction"</b>/>
* &lt;/operation>
* &lt;/portType>
* ...
* &lt;/definitions>
* </pre>
*
* <p>
* Example 2: Here is an example that shows if the explicit value for <code>Action</code>
* message addressing property for the service specific exception is not present.
*
* <pre>
* &#64;WebService(targetNamespace="http://example.com/numbers")
* public class AddNumbersImpl {
* public int addNumbers(int number1, int number2)
* throws AddNumbersException {
* 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;fault message="tns:addNumbersFault" name="InvalidNumbers"
* <b>wsam:Action="http://example.com/numbers/AddNumbersPortType/AddNumbers/Fault/AddNumbersException"</b>/>
* &lt;/operation>
* &lt;/portType>
* ...
* &lt;/definitions>
* </pre>
*
* <p>
* Example 3: Here is an example that shows how to specify explicit values for <code>Action</code>
* message addressing property if the Java method throws more than one service specific exception.
*
* <pre>
* &#64;WebService(targetNamespace="http://example.com/numbers")
* public class AddNumbersImpl {
* &#64;Action(
* fault = {
* <b>&#64;FaultAction(className=AddNumbersException.class, value="http://example.com/addFaultAction"),
* &#64;FaultAction(className=TooBigNumbersException.class, value="http://example.com/toobigFaultAction")</b>
* })
* public int addNumbers(int number1, int number2)
* throws AddNumbersException, TooBigNumbersException {
* 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;fault message="tns:addNumbersFault" name="AddNumbersException"
* <b>wsam:Action="http://example.com/addFaultAction"</b>/>
* &lt;fault message="tns:tooBigNumbersFault" name="TooBigNumbersException"
* <b>wsam:Action="http://example.com/toobigFaultAction"</b>/>
* &lt;/operation>
* &lt;/portType>
* ...
* &lt;/definitions>
* </pre>
