JSF Replacement for Struts?

I've noticed in a couple of posts, Bill, you suggested that JSF is a replacement for Struts.
It was my understanding a while back that JSF was supposed to be more or less a UI model that would tie very nicely into Struts. Now that JSF has added it's Nav and Validation components, it does seem like it would be in direct competition with Struts.
Do you have any idea how the industry is looking at this POV? Especially since the concensus is that Struts is the Defacto Intrustry Standard? Were my original thoughts on Struts true? Is it really just a Buzzword of the now? And JSF will become the new Buzzword until someone makes something more Buzzy?

Well there is certainly enough buz going on

I think that there will be a transition period but eventually just about all projects will be using JSF in one form or another. There is a ton of investment going into the JSF space so expect to see lots of tooling etc.
And as you said as soon as a more buzzy thing comes along JSF will be but a passing memory...

Awe the joys of Development.

Not necessarily a bad thing... evolving technologies keep app architects like myself employed!

Or just frustrates people like me all to Hell so much that I want to be a Garbage Man. They get paid really well where I live. It's all Unionized.

I know you better than that Gregg; without a learning challenge you'd wither and die.

You are probably right. I am usually the first one that jumps on the "ooooh, it's new, I have to try it..." band wagon.

I read on the Sun's site that JSF are not replacement of struts, rather these technology can be used together. Can you please elaborate on this part. How can two frameworks, doing almost same things can work together

Yeah, Prakash, I also think that they can work together and compliment each other... I believe that evolution of JSF won't let struts to be no use in the industry... Struts is now like a mature technology in the industry...
So we should hope something good from the evolution of JSF...

Hi All,
Struts and JSF can be used together. The idea is to allow us to transition to JSF gracefully. With the struts-faces tags you can use a JSF front end and continue to use your Actions, ActionForms, struts-config.xml etc.
We have a whole chapter dedicated to gracefully converting from Struts to JSF.
Over time though I expect that most new projects will use the whole JSF stack.
Hope this clears this up a bit.

There seems to be a lot of discussion concerning Struts, struts vs JSF, etc. Well, since I know zip about either, would it be advisable to spend some time with struts before/concurrently with learning about JSF?
TIA,
Mike

We are currently using Struts and want to move toward JSF. You mentioned that the there should be a transition to JSF. Does this mean that you recommend going fully to JSF or can the two co-exist indefinately?
If both are being used together, then are the <navigation-rule> tags for JSF used?

I am pretty sure that there are some <jsf-struts> tags that allow you to use Struts Actions. So the nav-rules would not be used.

I hope that this IBM DeveloperWorks might be useful for those, who are curious to know how to integrate Struts, Tiles and JSF...
As for me, the article is excellent to explain about this context...

Hi All,
The JSF/Struts integration is about
1) doing an orderly transition
2) using JSF UI Components but remaining on Struts navigation model
You can have them both coincide indefinitely but there is little reason to do so IMO. If you have an application that is currently running fine in Struts then leave it there. If you are doing new development then JSF might be the way to go if you have at least 6 months before you have to deploy to production.
The only reason that you'd have the coexist is if you have an existing Struts app that needs some UI Component and you don't have the time or money to rework the whole app. Then you'd want to use the integration tags to use the UIComponent in the UI but remain on Struts for your application.
I'm sure Craig would have a different take on the coexistence of the two...
Hope this helps!

Bill,
I am a bit confused and perhaps you can clear this up for me.
From the information on the amazon entry for your book...
"This innovative book arms you with the tools to utilize JavaServer Faces (JSF), a new standard that will make building user interfaces for J2EE� applications a lot easier."
Would that not mean that JSF would be the V in the M-V-C pattern? And Struts be the C? For that matter, you could use a different framework for the C and continue to use JSF?
Thanks,
Sharon

Hi Sharon,
Well I'd say just because you can does not mean that you should

While it is possible to use Struts as the controller with JSF as the view the only reason I can think of to do that is because you have to put a JSF UI on the top of an existing Struts app. You should not create a new app that uses Struts as a controller but JSF as the view.
JSF has a full MVC implementation and thus is able to 'do it all'.
The part that makes J2EE apps simpler is the way that you build the UI with JSF. JSF is simpler than Struts esp. with tool support.
Hope this helps!
