<div class="block">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>
@WebService(targetNamespace="http://example.com/numbers")
public class AddNumbersImpl {
<b> @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> <code>
&lt;definitions targetNamespace="http://example.com/numbers" ...&gt;
...
&lt;portType name="AddNumbersPortType"&gt;
&lt;operation name="AddNumbers"&gt;
&lt;input message="tns:AddNumbersInput" name="foo"
&lt;b&gt;wsam:Action="http://example.com/inputAction"&lt;/b&gt;/&gt;
&lt;output message="tns:AddNumbersOutput" name="bar"
&lt;b&gt;wsam:Action="http://example.com/outputAction"&lt;/b&gt;/&gt;
&lt;/operation&gt;
&lt;/portType&gt;
...
&lt;/definitions&gt;
</code>
</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>
@WebService(targetNamespace="http://example.com/numbers")
public class AddNumbersImpl {
<b> @Action(input="http://example.com/inputAction")</b>
public int addNumbers(int number1, int number2) {
return number1 + number2;
}
}
</pre>
The generated WSDL looks like:
<pre> <code>
&lt;definitions targetNamespace="http://example.com/numbers" ...&gt;
...
&lt;portType name="AddNumbersPortType"&gt;
&lt;operation name="AddNumbers"&gt;
&lt;input message="tns:AddNumbersInput" name="foo"
&lt;b&gt;wsam:Action="http://example.com/inputAction"&lt;/b&gt;/&gt;
&lt;output message="tns:AddNumbersOutput" name="bar"
&lt;b&gt;wsam:Action="http://example.com/numbers/AddNumbersPortType/AddNumbersResponse"&lt;/b&gt;/&gt;
&lt;/operation&gt;
&lt;/portType&gt;
...
&lt;/definitions&gt;
</code></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 <a href="../../../jakarta/xml/ws/FaultAction.html" title="annotation in jakarta.xml.ws"><code>FaultAction</code></a> annotation for an example of
how to specify an explicit value for <code>Action</code> message addressing property for the
<code>fault</code> message.</div>
