-<p>Most use cases can be divided into two phases. First, we need to change or
query the application’s state, and then we need
-to present an updated view of the application. The Action class manages the
application’s state, and the Result Type
-manages the view.</p>
+<h2 id="description">Description</h2>
-<h2 id="predefined-result-types">Predefined Result Types</h2>
+<p>You create this result programmatically in an action and return it as a
result of the action. No result definition
+is needed in <code class="highlighter-rouge">struts.xml</code>. See the
examples below how to use it. Please notice that the method result type is
<code class="highlighter-rouge">PlainResult</code>
+instead of <code class="highlighter-rouge">String</code>. Please explore the
API for more methods - if any is missing you can either extends the interface
+or report it in <a
href="https://issues.apache.org/jira/projects/WW/";>JIRA</a>.</p>
-<p>The framework provides several implementations of the <code
class="highlighter-rouge">com.opensymphony.xwork2.Result</code> interface,
ready to use in your
-own applications.</p>
+<blockquote>
+ <p>NOTE: This result is available since Struts 2.6 and it requires Java 8</p>

-<p>Additional Result Types can be created and plugged into an application by
implementing the <code
class="highlighter-rouge">com.opensymphony.xwork2.Result</code>
-interface. Custom Result Types might include generating an email or JMS
message, generating images, and so forth.</p>
+<pre><code class="language-Java">public class UserAction {
-<h2 id="default-parameters">Default Parameters</h2>
+ private String id;
-<p>To minimize configuration, Results can be configured with a single value,
which will be converted into a parameter,
-and each Result can specify which parameter this value should be set as. For
example, here is a result defined in XML
-that uses a default parameter:</p>
+ public PlainResult execute() {
+ return response -> response.write("User Id: " + id);
+ }
-<div class="language-xml highlighter-rouge"><div class="highlight"><pre
class="highlight"><code><span class="nt"><result</span> <span
class="na">type=</span><span class="s">"freemarker"</span><span
class="nt">></span>foo.fm<span class="nt"></result></span>
-</code></pre></div></div>
+ public PlainResult html() {
+ return response ->
response.write("<b>test</b>").withContentTypeTextHtml();
+ }
-<p>That is the equivalent to this:</p>
-
-<div class="language-xml highlighter-rouge"><div class="highlight"><pre
class="highlight"><code><span class="nt"><result</span> <span
class="na">type=</span><span class="s">"freemarker"</span><span
class="nt">></span>
- <span class="nt"><param</span> <span class="na">name=</span><span
class="s">"location"</span><span class="nt">></span>foo.vm<span
class="nt"></param></span>
-<span class="nt"></result></span>
-</code></pre></div></div>
-
-<p>Since probably 95% of your actions won’t need results that contain multiple
parameters, this little shortcut saves you
-a significant amount of configuration. It also follows that if you have
specified the default parameter, you don’t need
-to set the same parameter as a specifically-named parameter.</p>
-
-<h2 id="registering-result-types">Registering Result Types</h2>
-
-<p>All Result Types are plugged in via the <a
href="result-configuration.html">Result Configuration</a>.</p>
-
-<h2 id="extending">Extending</h2>
-
-<p>You can always extend defined result types and implement whatever logic you
need. To simplify process of that, you can
-define your custom <code class="highlighter-rouge">ResultFactory</code> and
use it with connection with custom interface which your Result implements.
-Check <a href="object-factory.html">Define dedicated factory</a> to see how to
do it.</p>
-
-<p>Struts 2 provides one such extension for you:</p>
-
-<p><code class="highlighter-rouge">ParamNameAwareResult</code> interface when
used with <code class="highlighter-rouge">StrutsResultBuilder</code> can limit
parameters assigned to the result.
-So you can simple extend existing result with such a functionality as
below:</p>
-
-<div class="language-java highlighter-rouge"><div class="highlight"><pre
class="highlight"><code><span class="kd">public</span> <span
class="kd">class</span> <span class="nc">MyResult</span> <span
class="kd">extends</span> <span class="n">ServletDispatcherResult</span> <span
class="kd">implements</span> <span class="n">ParamNameAwareResult</span> <span
class="o">{</span>
-
- <span class="kd">public</span> <span class="kt">boolean</span> <span
class="nf">acceptableParamName</span><span class="o">(</span><span
class="n">String</span> <span class="n">name</span><span class="o">,</span>
<span class="n">String</span> <span class="n">value</span><span
class="o">)</span> <span class="o">{</span>
- <span class="k">return</span> <span class="s">"accept"</span><span
class="o">.</span><span class="na">equals</span><span class="o">(</span><span
class="n">name</span><span class="o">);</span>
- <span class="o">}</span>
-
-<span class="o">}</span>
-</code></pre></div></div>
-
-<p>and then register it and use instead of default <code
class="highlighter-rouge">dispatcher</code> result.</p>
+}
+</code></pre>
