<p>Everywhere I look always the same explanation pop ups.<br/>
Configure the view resolver.</p>

<pre><code>&lt;bean id="viewMappings"
      class="org.springframework.web.servlet.view.ResourceBundleViewResolver"&gt;
    &lt;property name="basename" value="views" /&gt;
&lt;/bean&gt;
</code></pre>

<p>And then put a file in the classpath named view.properties with some key-value pairs (don't mind the names).<br/></p>

<pre><code>logout.class=org.springframework.web.servlet.view.JstlView
logout.url=WEB-INF/jsp/logout.jsp
</code></pre>

<p>What does <code>logout.class</code> and <code>logout.url</code> mean?<br/>
How does <code>ResourceBundleViewResolver</code> uses the key-value pairs in the file?<br/>
My goal is that when someone enters the URI <code>myserver/myapp/logout.htm</code> the file <code>logout.jsp</code> gets served.</p>

ResourceBundleViewResolver uses the key/vals in views.properties to create view beans (actually created in an internal application context). The name of the view bean in your example will be "logout" and it will be a bean of type JstlView. JstlView has an attribute called URL which will be set to "WEB-INF/jsp/logout.jsp". You can set any attribute on the view class in a similar way.
What you appear to be missing is your controller/handler layer. If you want /myapp/logout.htm to serve logout.jsp, you must map a Controller into /myapp/logout.htm and that Controller needs to return the view name "logout". The ResourceBundleViewResolver will then be consulted for a bean of that name, and return your instance of JstlView.
