    <p>I'm currently just exploring JSF 2 in the Java EE 6 stack.</p> <p>I find quite a bit of limitations with JSF and the way ManagedBeans are used is very counter-intuitive / odd:</p> <p>It seems that, in order to execute an action event, you have to use <code>&lt;h:commandLink&gt;</code> tag. Thats all well if I was for example, posting form data. However in this case, all I wanted to do was to simply view a book using the url e.g.: <code>viewBook?id=2</code>. If i was using spring, it would have been easy: </p> <pre><code>@Controller public class BookController { @RequestMapping("/viewBook") public String viewBook(@RequestParam("id") Long id, Model model) { // all the method params(id, model) are provided by spring BookDTO book = bookService.load(id); model.addAttribute("book", book); return "BookView"; } } </code></pre> <p>However using JSF, I have to:</p> <pre><code>&lt;h:form&gt; &lt;h:commandLink value="#{bookController.viewBook}"&gt; &lt;f:param name="id" value="#{book.id}"/&gt; &lt;/h:commandLink&gt; &lt;/h:form&gt; </code></pre> <p>and the backing bean:</p> <pre><code>@ManagedBean public class BookController { private BookDTO book; public String viewBook() { Long id = Long.parseLong(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterValueMap().get("id")); book = bookService.load(id); return "BookView"; } // ... } </code></pre> <p><strong>Question is</strong>: Is there a framework for JSF2 that provides what spring MVC does?</p> <p><strong>Another question is:</strong> What does JSF provide that couldn't easily be achieved using Spring ?</p> <p>In my view, the whole JSF / Facelet etc technology is overly complex, over-engineered and counter-intuitive. I hold the same view on EJBs btw.</p> <p>These views are formed after having explored Java EE 6, by writing a small Java EE web application.</p>

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.
