FaultAction


javax.xml.ws
Annotation Type FaultAction

@Documented
@Retention(value=RUNTIME)
@Target(value=METHOD)
public @interface FaultAction

The FaultAction annotation is used inside an Action annotation to allow an explicit association of a WS-Addressing Action message addressing property with the fault messages of the WSDL operation mapped from the exception class.

The wsam:Action attribute value in the fault message in the generated WSDL operation mapped for className class is equal to the corresponding value in the FaultAction. For the exact computation of wsam:Action values for the fault messages, refer to the algorithm in the JAX-WS specification.

Example 1: Specify explicit values for Action message addressing property for the input, output and fault message if the Java method throws only one service specific exception.

 @WebService(targetNamespace="http://example.com/numbers")
 public class AddNumbersImpl {
     @Action(
         fault = {
             @FaultAction(className=AddNumbersException.class, value="http://example.com/faultAction")
         })
     public int addNumbers(int number1, int number2)
         throws AddNumbersException {
         return number1 + number2;
     }
 }
 
The generated WSDL looks like:
   <definitions targetNamespace="http://example.com/numbers" ...>
     ...
     <portType name="AddNumbersPortType">
       <operation name="AddNumbers">
         ...
         <fault message="tns:AddNumbersException" name="AddNumbersException"
           wsam:Action="http://example.com/faultAction"/>
       </operation>
     </portType>
     ...
   </definitions>
 

Example 2: Here is an example that shows if the explicit value for Action message addressing property for the service specific exception is not present.

 @WebService(targetNamespace="http://example.com/numbers")
 public class AddNumbersImpl {
     public int addNumbers(int number1, int number2)
         throws AddNumbersException {
         return number1 + number2;
     }
 }
 
The generated WSDL looks like:
   <definitions targetNamespace="http://example.com/numbers" ...>
     ...
     <portType name="AddNumbersPortType">
       <operation name="AddNumbers">
         ...
         <fault message="tns:addNumbersFault" name="InvalidNumbers"
           wsam:Action="http://example.com/numbers/AddNumbersPortType/AddNumbers/Fault/AddNumbersException"/>
       </operation>
     </portType>
     ...
   </definitions>
 

Example 3: Here is an example that shows how to specify explicit values for Action message addressing property if the Java method throws more than one service specific exception.

 @WebService(targetNamespace="http://example.com/numbers")
 public class AddNumbersImpl {
     @Action(
         fault = {
             @FaultAction(className=AddNumbersException.class, value="http://example.com/addFaultAction"),
             @FaultAction(className=TooBigNumbersException.class, value="http://example.com/toobigFaultAction")
         })
     public int addNumbers(int number1, int number2)
         throws AddNumbersException, TooBigNumbersException {
         return number1 + number2;
     }
 }
 
The generated WSDL looks like:
   <definitions targetNamespace="http://example.com/numbers" ...>
     ...
     <portType name="AddNumbersPortType">
       <operation name="AddNumbers">
         ...
         <fault message="tns:addNumbersFault" name="AddNumbersException"
           wsam:Action="http://example.com/addFaultAction"/>
         <fault message="tns:tooBigNumbersFault" name="TooBigNumbersException"
           wsam:Action="http://example.com/toobigFaultAction"/>
       </operation>
     </portType>
     ...
   </definitions>
