example of rich internet applications (RIAs) using struts 2

[Ernesto Reinaldo Barreiro]

Hi,

I have been trying to find references to enterpise WEB applications, or Rich
Internet Applications, out there using struts2 but I have found
no references on struts 2 web site or in this mailing list. My apologies
if this information is available somewhere on the strust2 site or this
list and I somehow I just missed it.

Right now we are evaluating different technologies to be used for
WEB development at our company and struts2 is one of them (as we are
currently using struts 1 for development). In fact, one of the objectives of
the our quest is to select a Java WEB framework that allows us to easily
build Rich Internet Applications with lots of AJAX based widgets and AJAX
like functionality...

Any pointers to publicly available struts2 based RIA applications will be
welcome...

Best,

Ernesto

Hi Obinna,
Thanks for your answer...

I have seen and tried both the dojo plugin and the struts2-jquery-plugin in
an small showcase application I have built just to summarize (for internal
use) what is available for struts2 But to be sincere I'm not very
impressed about what they offer in terms of productivity and functionality
if you compare them with what you get using a component based frameworks
like Wicket.  Please, I have no intention to say that there is anything
wrong with those plugins, I'm a developer myself and I know how much energy
demands maintaining something... It is just that the way to work with them
seem to me unnatural after trying Wicket's AJAX implementation.

For instance, something I haven't found is a good free grid component
supporting AJAX navigation and advanced functionality like draggable,
resizable columns... Something like:

http://antilia.googlecode.com/svn/wiki/Grid.PNG
http://antilia.googlecode.com/svn/wiki/GridExport.PNG
http://antilia.googlecode.com/svn/wiki/Panels.PNG

So, I just was wondering what kind of tag-libraries, components, etc. People
use to build such applications...and how much effort was to build them...
and weather those applications where freely available just to see how do
they look and what kind of functionality I can expect to achieve...

Best,

Ernesto

Hi Erick,
Thanks for your answer!

In evaluating frameworks we are trying to see how they do satisfy the
following conditions:

-Easy of use and developers productivity. I know this sounds very vague but
I essentially mean things like. What components (taglibs in case of struts)
 do I get for free? How easy is to combine and use them? Are they
extensible? In here, I would like if possible to avoid having
our developers having to write tons of JavaScript/JSP spaghetti code which
at the end result in unmaintenable code... To illustrate this lets see what
takes me to build the table I have show at the image

Hi Erick,
Thanks for your answer!

In evaluating frameworks we are trying to see how they do satisfy the
following conditions:

-Easy of use and developers productivity. I know this sounds very vague but
I essentially mean things like. What components (taglibs in case of struts)
 do I get for free? How easy is to combine and use them? Are they
extensible? In here, I would like if possible to avoid having
our developers having to write tons of JavaScript/JSP spaghetti code which
at the end result in unmaintenable code... To illustrate this lets see what
takes me to build the table I have show at the image

http://antilia.googlecode.com/svn/wiki/Grid.PNG

HTML



 

Java

TableModel tableModel = new TableModel(Person.class, "id",
"name", "lastName1");

Table table = new Table("table",tableModel,
Person.createPersons());
add(table);

All the JavaScript, Ajax navigation, etc. is taken care by the component.
So, in JSP parlance I would like something like



and those objects added at the server side...

- Learning curve. How difficult will be for our developers to adapt to a new
framework.  Struts2 has advantage here because right now  we are using
struts 1.
- How easy will be maintaining the internal tools, components we create
ourselves and/or how stable-backward compatible are the external
components-tools we choose to use.

As for  Wicket AJAX implementation... You can see an example of how it works
here

http://wicket.apache.org/exampleajaxcounter.html

I think it deserves expending sometime looking at what Wicket does, even if
you don;t plant to use it, because you can get ideas of how things could be
done in different ways

IMHO, it is really a neat thing... because your don't have to know any Java
script library whatsoever and your can control at the server side which
components to update via AJAX. I didn't know about the grid

http://www.trirand.com/jqgrid/jqgrid.html

It looks really nice... I'll look into it and see if can make a neat
Component out of it...

Best,

Ernesto

I do agree there is no "fit all sizes" solution and you will always have to
find a compromise between having less complex components, that can be
combined to make complex things, and hight level ones that do a lot of
things and are less flexible/extensible. I would opt for having hight level
elements, that less capable developers can use to
achieve impressive results, and whenever you have things that those
components can do, then you come up with tailor made solution... Also it all
depends of the kind of applications you are building. For instance, in here


http://code.google.com/p/antilia/source/browse/trunk/com.antilia.web/src/com/antilia/web/crud/CRUDPanel.java

I have built a component that creates a whole CRUD screen out of an
annotated Entity. This hight level component covers a set of use cases, lets
say 80% of what you need in an application, and whenever you find something
not doable with it, then you turn to the tailor made solution...

Not quite following you here. In Wicket you normally attach events to
components in a programmatic way at the Java side and then when components
HTML code is generated the framework itself generates the (e.g. AJAX)
callbacks. All you have to do is what you want at Java code level and say
which components you want to refresh via AJAX (this at the Java level, the
framework itself will generate all the JavaScript necessary to get this
working). Think of something like the following (pseudo) code


TextField b = new TextField("b");

DropDownChoice a = new DropDownChoice("a" );
a.add(new AjaxFormComponentUpdatingBehavior("onchange")  {
 @Override
protected void onUpdate(AjaxRequestTarget target) {
if(target!=null) {
// do soemething to the model of
TexField b
target.addComponent(b);
}
}
});

This will generate a select and whenever you change the selected element you
will get notified at the server side, you do something that change the model
of textfield b, which determines what b will display, and then say you want
b update (target.addComponent(b)) . Thats all what it takes to do AJAX in
Wicket.

Ernesto

Hi,
I'm new to this list so I don't know how is who... but it was clear for me
from the beginning that Martin answers had no relation with my original
e-mail (that's why I didn't answer his first e-mail and only answered to the
second to be polite)... If you guys think someone is abusing the list by
repeatedly posting meaningless/confusing messages, isn't there an action
that can be undertaken to fix that?

Coming back to the original subject I would like to thank you all for
your time and well thought answers...

Best regards,

Ernesto

Re: Table(grids)

[Ernesto Reinaldo Barreiro]

After a similar question I asked a few days ago... I decided to create a
tag-library and some utility classes  that will make it easy
integrate jqgrid into struts2 applications...  I already have something
working but it is far from finished (see
http://code.google.com/p/antilia-struts/) and I'll be adding more
functionality in the near future. In fact, there is already a small test
application showing  how to use the taglib
http://code.google.com/p/antilia-struts/source/browse/#svn/trunk/struts2-jq-antilia-test

I
know there is already a struts2-jquery integration project.. So, once I have
something finished  I wouldn't mind if "my" code is integrated into the
standard plugin (of course if the developers of it are interested in
including my code).

Best,

Ernesto

Maybe just ? Or

Re: AJAX issues in struts 2.1.6

[Ernesto Reinaldo Barreiro]

I have no idea... This seems to be an entirely different thing form the
original post... But I'm new to struts2 so don't take my word for granted.
By the way, FilterDispatcher is deprecated. What I use in my toy application
is:

   struts2

org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
   

  
   struts2

Why not volunteer to help maintain them:-) It is opensource... Just follow
the list and you will see it is still very alive.

[Ernesto Reinaldo Barreiro]

Hi All,
A few days ago I asked the list for implementation of RIA applications in
struts2 and which components could be used. Someone, pointed me to

http://www.trirand.com/jqgrid/jqgrid.html

and mentioned there wasn't a tag integrating this GRID into struts2. So, I
decided to give it a try an created the following project

http://code.google.com/p/antilia-struts/

I have managed to create a tag that makes easier, or so I believe, to use
that GRID with struts. There is already a small demo application showing how
to use the grid tag. You can find the details on how to get it working here

http://code.google.com/p/antilia-struts/wiki/DemoApplication

And there is also a page explaining how to implement a basic search page
using the machinery provided by the project.

http://code.google.com/p/antilia-struts/wiki/SearchPage

I don't know if I''ll continue adding functionality to this project, because
it all depends on how busy will I be with other things, or if there is any
interest on this. So, in case YOU think this might be useful for the
community I wouldn't mind this code to be integrated into something else, or
get help in maintaining or improving it.

Best,

Ernesto

Re: How to display a table (data grid) using Struts2 - Is there a tag?

[Ernesto Reinaldo Barreiro]

Nice work! I also have integrated jqGrid into a struts taglib

http://code.google.com/p/antilia-struts

but have followed a different approach. Configuration is done at the server
side...
