Is there an open source survey engine for java that will allow branching of questions? i.e. Question 1 has the options of A, B, or C and they each take you to a different set of follow-up questions.
I've found a couple (JSurveyLib and Socrates QE), but those seem to be very tied to a GUI.
The application that I'm writing has a java back-end running on glassfish, and a flex front-end. Eventually there are plans for different font-ends, so the engine needs to be very independent of the GUI.
Please have a look at JCaiF - "The Java Computer Aided Interviewing Framework (JCaiF) is a collection of Java interfaces that define the common elements of a questionnaire or survey" - so perhaps you can implement your application against these interfaces.

Does anybody have an example or a tutorial for Android/Windows Application like viber? I want to understand how viber works and how it is programmed and how it works with different application.
I want to see an example that uses a message-chat-system that can work with different application.
I tested different way to do this but I faced with problems, so I think that I did not choose good way to do it.
Thanks.

I am trying to find a book which contains information and best practices in software development and design. More specifically I need a book which talks about how each layer talks to other layers, for example how the logic layer of the server talks to the data access layer and vise versa, or what information should the client application send to the server and how to do this.
Mainly I would like it to be for Java development but it doesn't really matter.
Patterns of Enterprise Application Architecture by Martin Fowler

written by Steve McConnell. I think it will be helpful.

I'm going to work on some project that would do a user-action recognition based on what he/she does in the system.
As far as I understand there are two main parts here :
intercept the user actions (say http traffic in web/ui interaction in thick-client)
analysis of user intentions
While the first part is rather technical and therefor easy to implement,
the second one is AI related and can be academic.
So I was wondering whether someone knows some third-parties/academic projects that would implement the 'action-recognition' stuff.
Thanks a lot in advance
I believe - Apache Mahout could help you. Look towards to collaborative filtering part of this framework.

There are lots of social engine based on PHP like SocialEngine and Boonex Dolphin, however I can't find one built from Java language. Is there any?
What I can find are just CMS, like Alfresco which is made with Java technology.
I'm not sure what you mean with social network engine.
If you want to host your own community try something like liferay. It has wikis, blogs, forums, etc.. You can integrate your own applications with it.
If you just want to connect to social services and integrate them into your application check spring-social.

Can anyone recommend a based open source mailing list software ?
The following would all be desired if possible:
Java as the underlying language, as we have people who are experienced with Java
Something which is packaged as a war and can be dropped into a Tomcat server
A sleek interface
Underlying data should be reasonably transparent
Good support for groups - sometimes we want to send mail to everyone, sometimes only people working in a certain area etc.
This is for a non-profit tax-payer funded research organization, so open-source (free) is a high priority. Thanks.
