"Forex" client consulting trace
a Forex company needs our advice about which web framework to be used for their future development. We had a little discussion about it here is the trace:
Here is a scenario where I need your client side advice, the company has an existing finance application written in JSP / MVC (self implemented).
The application's screens are very standard nothing unusual except the future console which has unusual designed gauge style charts.
The console is a Dashboard like therefor they need a strong layout to make it a bit dynamic. Other pages are in HTML standard and the server side talk is Java of course.
They want to rewrite their application (maybe with some reuse) and they asked for our advice about which framework to be used.
After a little thinking we have minimized the options to be Flex/ExtJS/Wicket. From that point we have some thoughts for what is the best approach.
Each framework can do the job separately or they can be put together for specific tasks as a layout (ExtJS/Flex) or as a custom chart(Flex) what is your opinion?
from what i understand it sounds like wicket is the best match for replacing their current application.
flex will not reuse any of their existing html and extjs is client side only, you still need the server side, especially if you want to keep the generation of HTML. wicket has good ajax support and you can easily use extjs widgets with it if you want.
you can also integrate flex for just the chart, but this may be an overkill.
One more thing, after reading Ittay's and Adi's responses.
I think that one of the strongest features of Wicket that it is aimed for Java users / developers.
If the team is expert in Java, and we don't want to overkill, I do think that Wicket is the best choice.
You didn't read well...
(Unless you write a shitty application, of course)
I understood from Lior that the development team's expertise are mainly in Java.
I'll explain why:
Wicket is a good framework, but nothing more. It will never get you where frameworks like ExtJS will.
(That is, of course, if we are there to support and backup the team in the first stages (at least) of the project)
Writing the described application using ExtJS and embedded Flex widgets is my choice.
As I see it wicket will be the main framework and either Flex or ExtJS will be used as the layout/custom chart.
Does Wicket has some solution for a decent layout?
if you mean something like a navigation menu, header, footer, etc. see borders (http://cwiki.apache.org/WICKET/consistent-page-layout-using-borders.html).
if you're talking about things like accordions, then this is in the realm of widgets - there are many widgets integrated with wicket, just google.
Isn't eliminating one is like eliminating the other?
Choosing Flex for on-line trading application might be a bad choice because of its single-threaded model.
Embedding Flex widgets inside an ExtJS UI gives you both good looking UI and the ability to update multiple regions concurrently.
It's practically the same...
2. ExtJS layouts over Wicket panels is a big no-no.
if their application is ok with being document oriented, or it is not very important that it will be very dynamic (meaning they get money from clients for some core technology), then turning to flex is just throwing away money (they will invest a lot of money and get something that will not generate more sales). in this case wicket is the best choice: the current team can learn it fast, the current application can be converted to it fast, and it then allows to move forward and add cool looking widgets (to the extent that all GUI is built with ExtJS widgets).
as an example, the GUI for managing netapp servers (storage) is one of the worst looking web application i've seen. and yet there's no reason for netapp to change that because the management is usually filling in simple forms (volume sizes) or navigating data and people buy netapp servers because they provide good storage, not the web interface.
The best options are ExtJS + Flex or just Flex the Wicket is actually a political choice since it looks like the same environment as Struts like
1) That's because most of them perceive it as snippets you add to 'onclick', it is actually a very nice language. i have a lecture i gave once which made the developers love (well, like) it.
3) political => business. if they want to convert their application to something very dynamic and commit to the cost to rewrite everything, then flex is #1 i think.
We will contact you as soon as possible.
