REST Module and MVC Framework

[gonzalad]

Hello !

I've just a simple question :

Do you plan to provide first-class support for the MVC part of JAX-RS 2.0 ? (the same kind of support you provided for JSF in Seam 2)

JAX-RS 2.0 MVC Support

From http://www.infoq.com/news/2010/11/jaxrs-2, we can see that JAX-RS 2.0 will bring a MVC architecture (see note 1). Does this means that we'll have a Struts like standard JEE 7 framework ?

If this is so, we'll have 2 standard web framework in Java EE 7 :

1. JSF


2. JAX-RS 2.0 MVC

Seam Support for JAX-RS 2.0 MVC ?

Seam provides perfect integration for JSF.

Do you plan to provide first-class support for the MVC part of JAX-RS 2.0 ?

Things like :

1. Bean Validation integration (ok you have it ;) ).


2. Support for templating (ok you're planning it - I think something like Jersey MVC http://blogs.sun.com/sandoz/entry/mvcj).


3. displaying error messages on the user interface (from Bean Validation or custom messages)


4. conversation handling


5. ...


6. and support with all this with whatever - at least JSP - kind of templating (not just facelets - this latter would lead to performance issues for high throughput web sites)

In Java EE, we have the JSF standard framework, but it cannot be used for high throughtput web sites or for site where accessibility compliance is a concern.

A standard Mvc framework would fill a gap here.

Gonzalez,

as you said, we do already have Bean Validation integration and the initial version of templating support is close to release. Initially, FreeMarker and Apache Velocity will be supported with infrastructure in place to enable other templating engines to be plugged in - so yes, it won't be facelets only. The other items you mentioned are not planned for the initial release but might get in later.

Thanks Jozef !

One question I have left about JAX-RS 2.0 MVC (since you're providing a subset of this spec with Seam 3 templating features - you surely have more info than me on this topic) :

1. Can I see JAX-RS 2.0 as the java counterpart to Microsoft .Net MVC ? (JAX-RS 2.0 MVC = Struts, or is it only to going to facilitate REST development ?)


2. If the answer for question 1 is yes, then I'll be eager to have more news about a the future portentials evolution of REST module in the MVC area !

We're using JSF in my company for most applications, but there's really a need for a basic MVC presentation framework.

If JAX-RS next step is to provide such a framework, then I'll wait for it - otherwise I'll need to choose an existing open source alternative.

Thanks very much for your input !

Microsoft ASP .Net MVC 3 is in RC2.

JAX-RS 2.0 MVC should or MUST be a copy of that from my point of view.

dotNet is now a better platform than Java, and it's up to Java to copy dotNet.

Here are some links :

1. ASP .Net MVC tutorial : http://www.asp.net/mvc/tutorials/getting-started-with-mvc-part1 (part1 to part 8).


2. ASP .Net MVC 3 http://weblogs.asp.net/scottgu/archive/2010/11/09/announcing-the-asp-net-mvc-3-release-candidate.aspx and http://weblogs.asp.net/scottgu/archive/2010/12/10/announcing-asp-net-mvc-3-release-candidate-2.aspx

ASP .Net MVC 3 Razor template is really impressive.

ASP .Net MVC3 also includes jQuery UI, unobstrusive client side validation, ...

I'm really persuaded that a Java EE platform with :

1. CDI as a basis.


2. JSF as the standard component framework


3. JAX-RS 2.0 and add-ons (copy of ASP .Net MVC3) as the standard mvc framework.


4. a very fast IDE with no turnaround (WITHOUT jrebel).

Would be a killer platform.

Without all that... Java EE will just keep being a very slow and cumbersome platform.
