    copied!<p><strong>Quickie</strong></p> <p>If you are using plain JSP views (as is most common), then simply add</p> <pre><code>&lt;% response.setStatus( 403 ); %&gt; </code></pre> <p>somewhere in your view file. At the top is a nice place.</p> <p><strong>Detail</strong></p> <p>In MVC, i would always set this in the view, and in most cases with Spring-MVC, use the <code>SimpleMappingExceptionResolver</code> to present the correct view in response to a thrown runtime Exception. </p> <p>For example: create and throw a <code>PermissionDeniedException</code> in your controller or service layer and have the exception resolver point to a view file <code>permissionDenied.jsp</code>. This view file sets the 403 status and shows the user an appropriate message.</p> <p>In your Spring bean XML file:</p> <pre><code>&lt;bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"&gt; &lt;property name="exceptionMappings"&gt; &lt;props&gt; &lt;prop key="PermissionDeniedException"&gt; rescues/permissionDenied &lt;/prop&gt; ... set other exception/view mappings as &lt;prop&gt;s here ... &lt;/props&gt; &lt;/property&gt; &lt;property name="defaultErrorView" value="rescues/general" /&gt; &lt;/bean&gt; &lt;bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"&gt; &lt;property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /&gt; &lt;property name="prefix" value="/WEB-INF/views/" /&gt; &lt;property name="suffix" value=".jsp" /&gt; &lt;/bean&gt; </code></pre> <p>If you need to implement a user login mechanism, take a look at <a href="http://static.springframework.org/spring-security/site/index.html" rel="noreferrer">Spring Security</a> (formerly Acegi Security).</p>
