Ajax support for Struts 2.2.1
Hi,
We have been using the Dojo plug-in in Struts 2.1.8 with some success and have been waiting with open minds for the new Struts 2.2.1 in which way they are going to go with AJAX.
I wouldn't mind some advice which AJAX plug-in's / toolkits people are finding working well with Struts?
Has anyone tried using the full Dojo within Struts, rather than just the historic built in tag libraries.
I don't want to have to remove all our Dojo references for another tool to find that this has limitations it has taken us long enough to learn the Dojo.
Kind Regards

We're using full dojo 1.5 but without any tag library and we are very happy
with it. We stopped using the plugin long time ago... it was always far away
from latest dojo release

YMMV; for me, my requirements are so different from project to project,
including requiring different underlying libraries. I have *some*
commonality, which I handle via JavaScript.

That's their loss, though--*any* customization requires knowing JavaScript
anyway. IMO it's more dangerous to lull users into a false sense of
complancency.

Until you're not, which for all but the most trivial usecases, is very
frequently.

Who can't write a JSP-based tag library? If they can't, they probably
shouldn't be coding in the first place.

Not only, but in the most cases. I have a medium size webapp
and there I am happy I can do the whole ajax stuff and the simple widget
stuff, like tabs and datepickers with an taglib. this is much more
comfortable and to maintenance as
plain JavaScript. And JavaScript is for the most Struts2 Users not the
language of choose. ;-)

Thats the point you refactor it, and after some change you
must refactor it again and again. This is a lot of stupid work.
With an taglib you are faster in your development process

The are not the same, but the basic task are mostly the same.

Of course you are locked in the moment you use it, or you have a
lot of refactoring after upgrade to an other framework.

And you reinvent the wheel in every project? You can wrote your own taglib,
but not every Struts2 User can do this.

As the creator of an AJAX taglib (As the developer of an AJAX taglb
(http://javawebparts.sourceforge.net/javadocs/javawebparts/ajaxparts/taglib/package-summary.html)
I have to say... I agree with Dave :)
There was a time (like, around the time I created the library perhaps?!?)
where I would have argued otherwise. And maybe it's true that in shops
with absolutely zero Javascript experience the tags still make some
sense... but in general, they don't really buy you anything IMO, and in
many cases will just get in your way. That's mine or anyone else' taglib.

There's not much boiler-plate code for that, and as with anything else, you
refactor your JavaScript. It's a function call, not embedded in the body in
keeping with good practices, etc.
And since no two apps are the same, what you need is almost certainly what I
need.
And I'm not locked in to a specific version of a specific framework.
And I could just as easily put *exactly* what I need into my *own* tag
library.
I can count on one finger the number of times an existing tag library
solution worked for me. I see almost zero benefit, except for the most
trivial use cases (as long as the tag library uses the JavaScript framework
I'm already using and does precisely what I need).
I'm not saying don't use them, I'm saying they're not that useful for me and
save me very little effort (if any), and occasionally make things *more*
work.

Hello Dave,
at this point i'am not on your side.
Even in the trivial cases a taglib has a benefit.
A normal AJAX request with a simple indicator and an effect after
completing,
needs a lot of boiler plate code, which is hard to maintenance and to debug.
A taglib make your JSP cleaner and you benefit from best practices from
other users.

A massive thanks to everyone's response.
I think we may try implementing the latest Dojo as we now have some
experience with this although I will have a look at the jQuery plug-in as I
have heard some good things about that.
Kindest regards
Matt.

Sure. It's just like using anything else without tag support; you use it as
you would with any back end system. And personally, for all but the
*completely* trivial cases, there's almost no advantage to using a tag-based
library since you have to write the JavaScript either way.
