    <p>The <a href="http://docs.oracle.com/javaee/6/javaserverfaces/2.1/docs/vdldocs/facelets/h/outputLink.html" rel="noreferrer"><code>&lt;h:outputLink&gt;</code></a> renders a fullworthy HTML <code>&lt;a&gt;</code> element with the proper URL in the <code>href</code> attribute which fires a bookmarkable GET request. It cannot directly invoke a managed bean action method. </p> <pre class="lang-xml prettyprint-override"><code>&lt;h:outputLink value="destination.xhtml"&gt;link text&lt;/h:outputLink&gt; </code></pre> <hr> <p>The <a href="http://docs.oracle.com/javaee/6/javaserverfaces/2.1/docs/vdldocs/facelets/h/commandLink.html" rel="noreferrer"><code>&lt;h:commandLink&gt;</code></a> renders a HTML <code>&lt;a&gt;</code> element with an <code>onclick</code> script which submits a (hidden) POST form and can invoke a managed bean action method. It's also required to be placed inside a <code>&lt;h:form&gt;</code>.</p> <pre class="lang-xml prettyprint-override"><code>&lt;h:form&gt; &lt;h:commandLink value="link text" action="destination" /&gt; &lt;/h:form&gt; </code></pre> <p>The <code>?faces-redirect=true</code> parameter on the <code>&lt;h:commandLink&gt;</code>, which triggers a redirect after the POST (as per the <a href="http://en.wikipedia.org/wiki/Post/Redirect/Get" rel="noreferrer">Post-Redirect-Get</a> pattern), only improves bookmarkability of the target page when the link is actually clicked (the URL won't be "one behind" anymore), but it doesn't change the <code>href</code> of the <code>&lt;a&gt;</code> element to be a fullworthy URL. It still remains <code>#</code>.</p> <pre class="lang-xml prettyprint-override"><code>&lt;h:form&gt; &lt;h:commandLink value="link text" action="destination?faces-redirect=true" /&gt; &lt;/h:form&gt; </code></pre> <hr> <p>Since JSF 2.0, there's also the <a href="http://download.oracle.com/javaee/6/javaserverfaces/2.0/docs/pdldocs/facelets/h/link.html" rel="noreferrer"><code>&lt;h:link&gt;</code></a> which can take a view ID (a navigation case outcome) instead of an URL. It will generate a HTML <code>&lt;a&gt;</code> element as well with the proper URL in <code>href</code>.</p> <pre class="lang-xml prettyprint-override"><code>&lt;h:link value="link text" outcome="destination" /&gt; </code></pre> <hr> <p>So, if it's for pure and bookmarkable page-to-page navigation like the SO username link, then use <code>&lt;h:outputLink&gt;</code> or <code>&lt;h:link&gt;</code>. That's also better for SEO since bots usually doesn't cipher POST forms nor JS code. Also, UX will be improved as the pages are now bookmarkable and the URL is not "one behind" anymore.</p> <p>When necessary, you can do the preprocessing job in the constructor or <code>@PostConstruct</code> of a <code>@RequestScoped</code> or <code>@ViewScoped</code> <code>@ManagedBean</code> which is attached to the destination page in question. You can make use of <code>@ManagedProperty</code> or <code>&lt;f:viewParam&gt;</code> to set GET parameters as bean properties. </p> <h3>See also:</h3> <ul> <li><a href="https://stackoverflow.com/questions/4888942">ViewParam vs @ManagedProperty(value = &quot;#{param.id}&quot;)</a></li> <li><a href="https://stackoverflow.com/questions/6377798">What can &lt;f:metadata&gt;, &lt;f:viewParam&gt; and &lt;f:viewAction&gt; be used for?</a></li> <li><a href="https://stackoverflow.com/questions/13249844">Bookmarkability via View Parameters feature</a></li> <li><a href="https://stackoverflow.com/questions/15521451">How to navigate in JSF?

    1. COI assume that it also doesn't matter if the `<h:outputLink>` is in an `<h:form>` - e.g. it can be, but it doesn't have to be, right?

    2. CONo, doesn't have to be. Only [`UICommand`](http://download.oracle.com/javaee/6/api/javax/faces/component/UICommand.html) components needs to go in an [`UIForm`](http://download.oracle.com/javaee/6/api/javax/faces/component/UIForm.html) component.

    3. COGot it. So - is there any other compelling case to use an `<h:outputLink>` other than pure page-to-page navigation?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
