Open Source Flex based framework for E-Learning...

Just wanted to let people on this forum know that there is an open source e-learning framework developed in Flex 3 available on http://www.gyatum.org. This framework has been named CrashCourse. It is in its preliminary stage at the moment but has the potential for expansion.

Most app servers have some built in container managed security (for example Tomcat Realms) which may or may not meet your requirements.

Open source role based framework

We have an application which is using :-
1) spring framework/j2ee code at the backend
2) while the front end is comprised of Adobe flex and action script. The app is web based.
A need of the application at the moment is for a role based authorization framework, based on which a decision can be made as to which widgets/tabs/screens should be visible to the user and which should be hidden from him.
Wanted to know
1) if somebody was willing to share some of his experiences on a similar project.
2) found and existing framework open source or otherwise helpful.
3) would recommend one architecture over the other
4) or anything else he would think might be beneficial to know.
Thanks

Hi,
Jim is right.
There is no way of converting/upgrading a VI to the newer version of LabVIEW without its block diagram. Below are a couple of KBs that discuss this issue:

How Open source Flex looks to a mid level developer

Here is my response to a post Matt made on a blog:
THe whole post:
http://blog.simb.net/2009/01/19/take-flex-back-for-the-community/
@Matt
1st off thanks, now my input:
The crux of your criticism seems to be that the process that we use for decision-making is closed its certainly not how we feel
Unfortuntly, this seems like a case of bad commuication by Adobe and the Flex team. If notable community experts get the impression of closed doors, then *certainly* the rest of us get this impression as well.
but there has been very little participation from the community so far
Im a solid dev, and not an expert but I can contribute in things such as testing and low level optimization; But, the Adobe open source site is a galactic disaster and discourages me from getting invloved. It has so many webpages that just go around in circles - filled with text that is verbose, this frustrates me to a great deal. As opposed to somehting straight foreward like:
http://framework.zend.com/download/latest
or
http://code.google.com/p/papervision3d/
Everything is here and easily notable. I avoid the seamingly endless pages and confusion. If I want to get to the Flex dev mailing list I have to register, then choose the lists, add the lists to my account. go though my account prefs read some directions.. then set up some other preferences..jeeeezzzz. If I want to submit a feature request I am directed to create another login for some Bug and Issue management? HUH? I thought I was submitting a featue request.
Right on papervisions google HOME page I see Getting started > Papervision3D Mailing List.
Next when I finially do get to Flex SVN, this trunk. is nothing like I have seen.what IS all this stuff and where do I go to learn about it? There are countless subfolders filled with things I vaguely understand and if I want to learn what it is. where do I go? Is there even a src folder?
Here is a classic example.
Flex trunk Read Me:
http://opensource.adobe.com/svn/opensource/flex/sdk/trunk/README.txt
vs.
Zend Trunk Read me:
http://framework.zend.com/svn/framework/standard/trunk/README.txt
*What* is the Flex team thinking with this?
I just spent 5 minutes or so twirling through all these SVN directories and Adobes website and I am clueless. I feel like the project is unessarily complex and disorganized - even if it isnt. This just convinced me to delete my Flex sdk bookmark on my SVN client.
Adobe just lost one potential contributor to Flex SDK.
We have another idea that were bouncing around that I hope to share in a week or two but wont get into now.
Saying stuff like this is what gives people the impression of closed. Why not post these ideas the Flex team has? Even if it is stupid or incomplete
Thats the whole point.

Wow, thanks for your response. This is great. I now understand that I had a combination of prejudice and ignorance when regarding Adobe Open Source. Perhaps my ignorance on these particulars is something that other devs encounter ( that whole perception thing ). I have chatted with people who consider the Flex SDK and Flex Builder... not the same... but fused together so much that it'd be just crazy to try and use one with out the other When I mention using Flex without Flex Builder.... people get that glazed over look in their eyes....( FYI I'm a FDT man, but am keeping a close eye on the new Flex Builder ) I'll use Zend as an example ( it's the best that I can come up with ) but I feel like there is a difference between the open source framework and Zend Studio ( commercial software ). Anyway, I'm really excited about how you've responded to all this. I have more ideas, but Ill sit on them and think it through and get ready for next weeks meeting.

XINS demos: http://xins.sourceforge.net/demo.html
Documentation: http://xins.sourceforge.net/documentation.html
User guide: http://xins.sourceforge.net/docs/index.html

I recommend you implement your web service with JAX-WS 2.0
Axis (both version) are good but why do you want to use something that is not included in JEE API, when Java provide same thing with better performance.
personally try to prevent non standard technologies despite they can be better than core java implementation sometimes.
I don't know Xfire.
the good:
-JAX-WS performance is better than axis,
- you can create your web service simply with annotation.(this means write class and then make it as a service easily)
- support every kind of service invocation(callback,Asynchronous,...)
- architecture is nice (you can operate on SOAP level)
the Bad:
- It is JEE 5 or JSE 6 dependent.
- there is seriously lack of documentation and examples for it, on java web sites and internet.

How to install open source Flex SDK in Eclipse 3.3 ?

Iam currently workin on UBUNTU 10.04 OS
I have downloaded flex_sdk_4.1.0.16076.zip
How to install open source Flex SDK in Eclipse 3.3 ?
Thanks in advance,
Jai.

Hi Jai!
I'm not sure about this information because the last time I have used the flash builder into a linux machine was in 2007, but check this out:
http://labs.adobe.com/technologies/flex/flexbuilder_linux/
It says you will need to use SDK from the command line to build flex application.

Source Code Editor Framework for Flex

Dear Flex Forum members:
As a Flex newbie a quite important question in relation to the "Flex frameworks world" still remains to me, even after some google search sessions:
Does there exist any (preferably free) Flex framework or Flex component covering the functionality of a source code editor with syntax highlighting and syntax checking? -- Anything comparable to the Editor Framework within the Eclipse RCP (Rich Client Platform) or even to the Eclipse GEF (Graphical Editor Framework)?
The background is as follows (and as described in more detail in my first post to this forum):
An Online Shop Management Component shall offer the ShopManager to specify the products and offers in some declarative way and after a pre-defined grammar in place. The application frontend must be realized in Flex, and that's the reason why I'm now searching for:
some kind of textual or graphical editor framework for realizing the Shop Manager's editor which shall support him/her in creating shop specifications/configurations in a grammar-conforming way through syntax color highlighting and syntax checking (error feedback), and
this editor framework being intended for Flex (i.e., being a flex framework)
In some way, much of the editing/modeling functionality is identical to the one offered by Flex Builder (Eclipse application), but in my case this functionality must be exposed as web application (Flex component running on the browser).
Aps., would it also be possible to realize the Shop Management Component as AIR app, distribute it through a web page and run it locally on the Shop Managers client desktop???
Which products/frameworks do you know for accomplishing this task?
Thank you very much for any help.
Best regards
Alessandro

Since people complain about Flex's basic rich text editor (which is a basic building block of the kind of framework you're discussing), I doub't you'll find what you need out of the box anywhere...

New, open source JavaFX OSGI framework

First, a disclaimer: this is an open source project I started, and somebody may regard it as advertising (basically, it is ). I'm not sure if it's against forum rules. If so, please delete this thread.
Basically, it's a framework for developing modular applications based on OSGI. It should provide support for building applications for desktop, web and mobile devices. It's called DEMUX Framework. Published under Apache License.
http://demux.vektorsoft.com
So far, support is available for desktop applications based on JavaFX, and mobile apps for Android. Since this is JavaFX forum, I would like some feedback from people who work with JavaFX. Basically, is this something you would find useful and worth spending time developing?
If you have some time to throw away, give it a try. Please note that this is early stage development, so you will probably get frustrated and annoyed, buty ou should get the general idea.
Documentation and some code samples are available on project wiki: http://demux.vektorsoft.com/wiki
Source code for samples is available as part of binary download: https://bitbucket.org/vektorsoft/demux/downloads
Any feedback is welcome.

hi,
here's a thought stop spamming this forum with your crap....

EJB 3.0 in a real world open source project. Great for coding reference!

If you are interested in seeing EJB 3.0 implemented in a real world project (not just examples) or if you are interested in learning how to use them I suggest you to take a look a the open source project Overactive Logistics.
It has been written totally using EJB 3.0 (session and entity beans) I found it very helpful in solving several technical situations I was facing.
You can get more information at:
http://overactive.sourceforge.net

Thanks for the ponter, I will check it out.

Microsoft open sourced the Entity Framework

http://weblogs.asp.net/scottgu/archive/2012/07/19/entity-framework-and-open-source.aspx
Microsoft wants others to get involved in building the next version of the Entity Framework.
The source code is found here:
http://entityframework.codeplex.com/
The Mono Project is working to get the open sourced Entity Framework to work on Mono.
So, with Oracle working on a thin ODP.NET provider, hopefully, it will work on Mono too. But no guarantee from Oracle. I know at first, the thin ODP.NET provider will not support Entity Framework, but down the road it could (hopefully).

I'm using NHibernate and I'm more satisfied with it than EF.
Alex said that the final release for managed provider will come with Oracle 12 which maybe will come at the end of the year.

Open-sourced Java-based Webcam server/app available?

[If this thread does not belong here, please let me know where I can post this request!]
I was hoping to find an open-sourced java webcam application/server that is capable of recognizing various webcam (or video-capture) devices and is modular enough that new devices can be added as needed if missing.
Does anyone know if such an application exists and if so can you provide the URL links?
Kind regards,
Dan

If 7.0 was released, how come http://www.sun.com/webserver still only talks about 6.1?

Looking for open source project in JSF for learning

Hi,
I am quite a beginner to JSF, I think it will be good to read some existing source code, could anyone recommend some projects that I can turn to? I am particual interested in an online text editor.
I think currently I could understand how the jsf works, its relationship with jsp, html, css,and how It could cooperate with AJAX. and I have written a small amount of web pages , which were aimed at providing a blog-publish like service. That's why I am interested in online text editor. But any other capable project would be also helpful for me.
Thanks.

You can find (simple) samples here:
[https://javaserverfaces.dev.java.net/servlets/ProjectDocumentList?folderID=4036&expandFolder=4036&folderID=0]
[http://www.coreservlets.com/JSF-Tutorial/]
You can find a HTML/rich text editor as JSF component in the Mojarra Scales component library: [https://scales.dev.java.net/htmlEditor.html].

Find Source IP of Router for Route Learned via BGP

Hi All,
45 minutes of searching documents and google, and I cannot find a series of commands that will help me identify the Source IP of the router which advertised a route. The router I am accessing is the on-premise router, and only has one neighbor from which it learns all the routes.
I recall being able to do this fairly easily in the past.
Regards,
Jerry

To clarify,
If I do
show ip bgp neighbor 10.100.100.2 route
I see about 100 routes learned from that neighbor.
Is there any way to track down where each of those routes came from?
Thanks in advance,
Jerry

Need information on open source testing tools for ADF web applications

Hi experts,
I need to investigate on new feasible open source Java testing tools for testing ADF web applications. I have tried to google a lot but getting confused.
My requirements as as under:
1. The tool must be open source.
2. It should be easy to understand and to work upon by the tester and developers.
Selenium based testing approach is already in place for testing the application but need to search for tools other than Selenium which shall prove suitable for testing ADF applications. Kindly let me know your inputs / suggestions.
Thanks a lot in advance.
Neelanand

Hi,
Have a look at JMeter http://jakarta.apache.org/jmeter/index.html
1. The tool must be open source.It is.
2. It should be easy to understand and to work upon by the tester and developers.I guess it is.
There are some specifics in configuring it for ADF, but Chris Muir wrote a nice blog about how it's done, check it out http://one-size-doesnt-fit-all.blogspot.com/2010/04/configuring-apache-jmeter-specifically.html

Jdeveloper 11g always go with wizard. I personally like visual jsf desinger of jdeveloper.
But other thing i want to code. To understand properly.

There isn't an end to end tutorial with the stack you are looking at, but:L
You can start with this tutorial that uses EclipseLink for JPA to build the model layer:
http://www.oracle.com/technology/obe/obe11jdev/ps1/ejb/ejb.html
Here is a little example of how you can use Trinidad components (open source) in JDeveloper 11g for visual JSF development:
http://blogs.oracle.com/shay/2009/02/using_trinidad_in_jdeveloper_1.html
using MySQL would just mean adding the MySQL JDBC driver to JDeveloper, and to the integrated WebLogic - like this:
