The story so far

In part 1 we covered getting our SE app started and the Jetty and Weld containers started to provide us with a servlet and CDI capabilities. In part 2 we added support for RESTful webservices with the Jersey implementation of JAX-RS.

Now its time for some UI, for this we’re going to setup setup JSF using the Mojarra 2.1 implementation.

As always a fully working project to go along with this post is available here.

Java Server Faces

Lots of people love JSF and a lot of people don’t. In general I am not a frontend hacker, and to be honest when I have to do it (and I am usually forced to use a UI framework) I find myself wishing for plain old HTML or that new cool term POH5. Now whether this is the fault of Java, the UI framework or GASP a failing deep within myself I am not sure.

My experience is that JSF makes writing web applications in Java feel the least like trying to parallel park an articulated bus.

Remember the real problem with web development is that some always mentions wanting support for some version of Internet Explorer ;)

So all of that said how do we go about doing this? Well its really pretty simple at this point. We have most of the environment in place already, all we need now are a few extra dependencies, a bit in the web.xml and a faces-config.xml.

The four dependencies that we need are the Mojarra JSF API and implementation, JSTL and lastly a EL implementation (we added the API in part 2).

Above we ask Mojarra to configure JSF for us and we setup the EL implementation.

If you check out the example there is also a DeedController bean, and an index.xhtml you can build and run the example and point your browser at http://localhost:8080/faces/index.xhtml.

In part 4 we’ll setup JPA and using CDI make our EntityManager injectable and setup container transactions.
