Comparisons on Flex MVC Frameworks

Hi,
I have been doing a comparison Cairngorm, Swiz, Mate, and PureMVC. I plan on presenting my analysis to the developers at my company and my blog. Before I do so, I want to reach out to the maintainers of each project for comments. I feel offering to do so would be the more fair thing to do.
However, I'm not sure what's the best way to send my analysis and example applications to the maintainers of this project. I feel that posting my analysis on this forum is inappropriate at this time. What would be the best way to get in touch with the maintainers of the Cairngorm project?

Thank you for your quick reply, Alex. Since my post yesterday, I came across quite a few comprisons (not an exhaustive list of what I had to read through...):

http://www.adobe.com/devnet/flex/articles/flex_framework.html
http://tv.adobe.com/watch/360flex-conference/mate-flex-framework-by-laura-arguello/
Because I'm looking for a non-intrusive (or loosely coupled) framework with a gentle learning curve (so that my company's current Oracle Forms developers won't immediately reject it), I'm tempted to try out Mate. And because the framework doesn't interfere with views, business logic and server access, it seems that I'll more easily be able to back out and try another one if I find out I made a mistake (something that's tougher to do with Cairngorm or PureMVC).

Hey Jan,
Oracle's E-Business suite is moving to a JSF solution. This is really for three main reasons (abbreviated version):
1) JSF is much more focused on the 'view' components. The component model has a clean separation of the component definition from its rendering. This, among many other things, allows us to provide a consistent development environment and APIs for developers building apps for browsers, mobile devices, telnet devices, etc.
2) JSF has a better defined lifecycle. The JSF lifecycle maps much closer to the phases that enterprise applications need when processing data from a web application. We are able to easily extend this to add things not currently in the spec, like portlets, wireless, etc., as well as more easily plug new components into the framework.
3) Once you remove the JSP tags & FormBean from Struts, all you are left with is the navigation. There is nothing special in the Struts navigation that would cause us to try to make the two technologies work together. In fact, the Faces navigation will not be robust enough in its current form to support the declarative navigation requirements for Oracle apps. We plan to extend the JSF navigation and then work to submit that back into the standards.
Hope this helps,
Ted Farrell

Should I use a MVC framework for an large RIA application

The book of "Adobe Flex 3 Training from the Source" does not
talk about any MVC frameworks in its
eCommerce example. I think Flex's events, functions, and mx
components are MVC already. Do they have to be in separate file to
call them MVC? I do not find that core Flex is harder to read and
understand than using a MVC framework. I think using the MVC
framework would hurt the performance because too many additional
events are dispatched. Any comments?

MVC is one design pattern that is pretty darn useful for a
lot of applications, IMHO. There are frameworks that more or less
force you to think in MVC pattern terms, like Cairngorm and
PureMVC. But you certainly don't need to use a framework to create
an overall design pattern of model, view, controller. However, it
sure can make it easier if you're doing a large project. The book
you're talking about is a good example. They don't use a framework
but they have tried to use a form of MVC in the way that they
implement all the components to ensure things are loosely coupled.
As far as hurting performance, I'm no expert but there are so
many thousands of events occurring all the time in Flex that you
might actually enhance performance if you take more control by
using custom events of your own creation within a well designed
framework.
I'm a fan of the Mate because I get it and it doesn't impose
a strict structure like Cairngorm. I don't have a whole lot of
experience with OOP (though I'm sure getting it thanks to this
forum). Many others have their own opinions and will surely
recommend other frameworks. However, the bottom line is that if
you're doing a big project, I would think it would be a huge help
to at least have a conceptual framework approach in your mind, if
not part of the code.

Great exercise to document the problem like this. It got me thinking about how an app with modules would be different from an app that does not use modules. Solution: I moved the dummy reference of PersonPhotoView out to the main application file (as opposed to being inside the module) and it worked. I've probably been lucky not to have experienced this problem earlier, because for most other entities I have an instance attached to my model which is linked / compiled with the main application.

[Automation] Differences when using Flex Automation Framework ?

Hello everyone,
I recently made some tests with Flex Automation Framework and noticed that using it slightly change the application behaviour.
First, it changes the way container intercept dans handle mouse event as expalined in Adobe JIRA ticket #791:http://bugs.adobe.com/jira/browse/FLEXENT-791
I'm using sdk 3.2 so it won't be fixed. However future releases (3.4+ and 4.0+) should not have this problem.
Secondly I notice that using RuntimeLoader.swf on my application remove the text of some labels I have in my login form.
This does not happen when compiling the application with automation libraries.
Does anyone experienced other bahavioural changes when using automation ?
Thank,
Olivier

Hi Olivier
The only change which we know of is the one that you rightly pointed out in bug http://bugs.adobe.com/jira/browse/FLEXENT-791 . There are no other behavioral changes that occur when you compile your application with automation.
With regards to your statement
Secondly I notice that using RuntimeLoader.swf on my application remove the text of some labels I have in my login form.
This does not happen when compiling the application with automation libraries.
Can you please send us a working sample of this issue as we have not come across this behavior before.

Deployment and configuration of MVC framework

Guys,
I have a scenario where I need to deploy one of PHP MVC framework and use Oracle 10g web forms back end queries .
Have anyone done anything similar ? Appreciate if you people give me some ideas considering me as a new bee to oracle 10g forms .
Thanks

There's a framework here for MVC generically, how you're going to craft them into the forms ... well that's a thought. I'm not sure how that might be done. My generic guess is: You'll have to generate the web form and then write your own integration script or manually integrate the code.

MVC Framework

Hi, We're working with the MVC Framework. The personnel application is running very good. But when we try to create our own application and have a problem. We use Rational Rose to generate the service xml file and it works good when we use standard process, like CreateJSPPAge, ProcessRouter, DisplayGroup, etc, all that comes in the cle package. But the problem is when developing a persisting process that is not in the satandard process, like the GetDepartment in the personnel example. Orion throws the following error when accessing the controller:
"XML-0108: (Fatal Error) Start of root element expected"
We are creating process with the process generation tool. ?Does anyone one have an idea that can help me to find this problem?
Thanks
Alex

Sure!
Here's a snippet of the xml file where the error comes from.
The problem is in the "inicio" process group. If I comment the process "sitiocontenidos" it works fine, but if I try to use it, I got the exception error.

2>>10 Jsp's
3>>7 UserServices class (BussinessLogic class)
4>>3 bean class (for getter and setter methods)

to implement all the above points in the MVC framework
please help
Thanks all

Hi,
MVC stands for
M ---- Model (Business Logic, FormBeans, Database Related)
V ---- View (JSP, HTML etc..)
C ---- Controller (Servlet)
This is how you have to use MVC Framework.

Mvc framework and stored procedures ?

Is it possible to keep high productivity of the mvc framework and still use stored procedures as with Cocobase, Castor,etc?
Thank you in advance.

If your question is, "Can the Business Components for Java J2EE Framework easily use stored procedures as datasources?"
The answer is yes. See the sample that we ship in the .\BC4J\samples\StoredProc directory.
If you're meaning the Oracle9i MVC Framework for J2EE which is produced by Oracle Consulting, then it's best to ask the question the "Project Cleveland" forum here on the OTN forum.
thanks.

Regarding RESTful WEB SERVICES with SPRING MVC Framework

Hi,
Can anyone explain me about RESTful WEB SERVICES with SPRING MVC Framework .
It is urgent for me.
Thanks
Venkat Jalli

Hi Manoj,
I am also new to Spring MVC portlet. But, I tried to see the difference between sample spring portlet and your code below. Issue that I can see is, in your code, you have not mapped your servlet container with portlet application. So, in theory, your servlet containder do not know that you have a servlet. Let me try to explain from sample portlet,
In portlet.xml, they have something like below:-
<portlet-name>swf-booking-mvc</portlet-name>
<display-name>Spring Webflow Booking MVC</display-name>
<portlet-class>org.springframework.web.portlet.DispatcherPortlet</portlet-class>
And in web.xml, they have below:-
<servlet-name>swf-booking-mvc</servlet-name>
<servlet-class>org.apache.pluto.core.PortletServlet</servlet-class>
<init-param>
<param-name>portlet-name</param-name>
<param-value>swf-booking-mvc</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
This web.xml is for Pluto portlet container and there will something similar for Weblogic portal as well that I am trying to figure out :(
Thanks,
Sanjeev

How to deploy coldfusion as mvc framework from server standpoint?.

Does anyone know how to deploy mvc framework from server
standpoint?. I have all my business logic as cfcs but I want to
move them to different server so that my cfm code is in one server
and my cfcs are in another. Has anyone done this or point me in the
right direction?.

Actually that's exactly the way we have our new high
availability
environment configured. All the code runs off an EMC device.
Not sure
why I didn't draw this parallel yesterday with running the
CFML on one
server and the CFCs on another server--as long as you have a
sufficiently fast network (we're on gigabit) and
device/drives (our
stuff is fiber channel), then as you mention below
performance probably
isn't an issue. I'd be curious if doing this over 100 megabit
with more
low-end hardware would perform as well as having things on a
local
drive, however.

Yep, very true, and although the NAS/DAS device isn't
*directly*
accessible via the web, remember that's it's accessible by
the user
that's being used by the web site users, so there isn't a
huge security
benefit here vs. having the code locally. You're absolutely
right

silly, when if you

Yeah, this is where we head was earlier in the
discussion--putting the
CF "pages" on one server and the CFCs on another just seemed
a bit wacky
to me.

Right, this is what we do on our production environment but
we don't
even use a CF mapping (though you could). We just point our
web server
to the EMC device and everything else just falls into place,
provided
you've set up the user CF and your web server process (or
using "connect
as" in IIS in W2K3) are running as so they have access to the
network
storage device.

True, good point. We have extremely good performance (might
even be
*faster* than local drive speed) with our EMC device, and
again I'm not
sure why I didn't see this parallel yesterday in the
discussions. Blame
it on a very hectic week. ;-)

WebCenter Sites and Model–view–controller (MVC) framework

A customer of our started developing their sites using Webcenter Sites, they want to support additional functionality such as transaction management, exception handling, custom logging and so on. I was wondering if anyone has experience with the Model–view–controller (MVC) framework, they consider it an ideal candidate for these features. Has anyone here used the MVC framework in conjunction with WebCenter Sites to write additional java classes, facade layers and utilize the Spring controller to wire the same ? Are you aware of any other options available for this purpose ?
regards,
Pietro

Hi Pietro -
Using Sites IN a MVC framework is very difficult, because the entire context of WebCenter Sites is burned into the COM.FutureTense.Servlet.SContentServer servlet. You can't really work around that with any degree of reliability. Unfortunately, that means that dropping Sites into a pre-existing third party MVC framework doesn't really work.
There are a lot of good reasons for that, not the least of which is the two-tiered pagelet-level caching system that makes Sites so very fast at delivery... not that it's any consolation.
To deal with this some former colleagues of mine and I built the GST Site Foundation ("GSF") framework, which provides a Spring-like MVC container WITHIN sites, instead of the other way around. If you're familiar with Spring, you'll see patterns similar with the GSF. My current team and I have blogged about this extensively:
What is this whole GST Site Foundation thing? | Function1
Create a Simple "Contact Us" Form with GSF | Function1
How to Add Your Own DAO to the GSF Actions | Function1
The full stream is here: GSF | Function1
But ultimately, the special sauce is the following: in Sites, create an XML element that contains nothing but a <FTCS> tag, a <CALLJAVA> tag, and a closing </FTCS> tag. Your CALLJAVA will then call a class that implements the Seed or Seed2 interface, and from in there you have access to the (properly managed) ICS object where you can do all of your magic. You can then build a lightweight controller here to handle any action you can dream up:
https://github.com/dolfdijkstra/gst-foundation/blob/master/gsf-wra/src/main/java/com/fatwire/gst/foundation/controller/A…
Let me know if I can help!

Tony
