I am a java developer and am pretty comfortable with develeoping webapps in java/jsp/servlets.
I want to develop a video web based chat website.people should be able to chat with each other using my website.People dont need to use any client app installed on their pc in order to chat with others.
My website should be scalable.It should be able to support many hundreds of user simultaneously.I heard that there is a framework cal is beastled twisted matrix in python that best for developing such kind of servers.But learning a new language of me is not feasible as i dont have much time to get the system up and running.I have 2 months to get the application up and running.
After googling i found that twisted matrix ix best for the puropose.
So what should i do?Should i go ahead with java or python?Which java framework to use?If i develop it in java should i develop a web app which will run on top of app server? or shold i develop my own chat server in java?
Any pointers will be helpful.
I'm a little confused: the requirement is that users don't need any software installed on their PC? How can that be? You need something.
Given two months, I think you only have two options:
Flash
Skype
Like you said, because you have two months to get it up and running, you're best off not learning a new language. As far as Java network frameworks go, people seem to have pretty good experiences with Netty, MINA, or Grizzly, but going that low-level will probably cause you grief.
There's some good stuff on SO too:
API to broadcast live webcam
Just Try Cometd， CometD is a scalable HTTP-based event routing bus that uses a Ajax Push technology pattern known as Comet. There is also a chatroom example in the sourcecode.
Cometd is based on Jetty Continuation。
Using Long pooling.

I have been doing research for days and am so lost because everyone implements this differently or these tutorials are unclear.
I will be writing a web application that uses API's from sites like AWS, CROWD, etc. to create a single-sign on portal to manage many different things.
I have never worked in web development before, so this is all new. How should I get started in this project? What exact files will I need to create? Any advice would be helpful.
The only constraints that I have been given is that this will run in Tomcat, so I need to use java.
You need to understand the basics of client - server architecture and develop a
web service to standardize the REST based actions such as RPC.
I am new to mobile application development and wanted to know from experts here on how they approach the server-side design. I need to support cross platform clients (iOS, Android, Windows) and require a scalable backend architecture.
What are the widely deployed server-side strategies
Are there any Mobile specific open source server-side technologies available.
What factors people consider for mobile application back-end.
I agree with half the answer above. You should use REST architecture - it is the most straightforward way to go. I use Ruby on Rails for my mobile projects. It is quick to start building the server code and see it working in somewhere like heroku.com almost instantly.
So I'd pick the following:
ruby on rails - worth your time picking up
heroku.com for deploying / or EC2 if you pick the Rubber gem
Google App Engine is another great option if you know some python / java
REST architecture
store all your heavy images etc with Amazon S3. They have some great SDKs to work with.
get yourself some JSON libraries to communicate with your server
on iOS:
use MKNetwokKit (it will save you lots of trouble down the road. it helps you cache and its a nice architecture all around).
if the app is small, try a data model based on NSArchiver instead of CoreData (SLOWWW). Mogenerator is a good start (this isn't server related..)
If you hate writing server side, I'd advice you to checkout Parse.com. Completely mobile only development with all server code handled for you. For big projects, you really should write your own server stuff.
Some extra things I'd consider:
how would the security work? just a session token in the HTTP header?
tier your app -- networking / MVC
what happens when you're offline? - this is currently something we're dealing with after not having thought early - pain.
I've had good success with creating a server using REST web services and XML data, but would recommend JSON instead. You can create this using Java and host it using Tomcat. This is widely deployed and widely consumable by multiple mobile and even non-mobile technologies.
A couple of factors to consider:
* You'll probably want it in a DMZ and being Internet accessible so think about firewalls, reverse proxies, and encryption via SSL.
* Will you host the server or sell the server to customers? Hosting is easy. If selling, there are many more considerations.
I'm creating an android application. Most of the functionality will be done offline, however I need to build some dependency between users of the application, such as being able to see peoples "high scores" and to communicate between users, and sending each other in-app messages.
Therefore, I'll need a webserver which the app can connect to in order to store such information. I imagine the app will make REST calls to get high scores.
I'm trying to avoid the overhead of having to create a fully functional web application (SpringMVC for example). Is there any application that makes this simpler?
What is a good, simple web stack I could use for this?
We use the Java RESTlet framework for creating RESTful interfaces for our mobile apps, and deploy via Google AppEngine. I shared a series of screencasts on YouTube demonstrating this approach that you might find useful. The RESTlet framework used in the screencasts is a few versions old, but this should help you get up to speed fairly quickly. We like this particular approach because it's straightforward for Android developers (who are already proficient in Java), scales well, and its free until you hit Google's quotas.
I will make a video chat website, but coming from PHP and Python for the web i have no experience with video steaming.
What do you recommend? Java or Flash? What's more flexible ?
I am thinking of even making a C++ server application for stream controlling with a PHP fronted. Since is going to be a high traffic website and performance is a must.
Can you point to some direction?
Any documentation? Framework?
I'm going to warn you: this is no small project. There's a reason why most prepackaged video chat websites and services cost hundreds of dollars a month.
First off, you need to pick your client side runtime. This is a major decision, since it will impact your available client base, and the cost of entry for your site. Flash is hands down the most pervasive, but Java is fairly prevalent in the techie culture. Silverlight less so, but you should check the latest statistics. Note that you should pick a particular version you're going to develop for, since the APIs may change, and market penetration is different.
Once you've developed the client-side code, you'll need to pick the server environment. If you use Silverlight, obviously you need to use C#.NET to develop the server side code (for the video streaming). Both Java and Flash as clients use Java as the server-end.
If you choose to go with Flash, be aware that you can either go with the official Flash Media Server, or you can go with the open-source Red5 server.
As noted by SEK, you should proceed with caution since providing a reliable streaming service might not be as easy as it sounds.
I would recommend reading about streaming (what it is/means, technologies, etc) and then moving on with the implementation.
Serving streams to clients
Solutions like the Flash Media Server, might give you less headaches. Red5, as previously mentioned is a 'nice' open source solution, although i am not sure about the capacity and stability.

Google is always your friend on this big topic..good luck.
We are in the middle to evaluate the technology choice to re-design an operator console application. The operator console as a hosted contact center has the abilities to queue the inactive calls, and hold, answer, transfer the active calls.
The legacy operator console used Java Swing. We want to use the latest RIA technology (Flex/Silverlight) to retire the legacy one. But the question is Flex/Silverlight can implement the functions like hold, transfer the calls? Based on my experiences, Flex can listen Java socket to receive XML data? Does it work well to receive voice data? Thanks.
Flash / Flex does have native access to the computer's microphone with the introduction of the latest player / AIR runtimes. But, that is probably not what you need.
Yes, Flex supports open sockets and can listn to a server. To receive voice data, you'll be best served using something on the server side, such as Flash Media Server or Red5.
I'm not sure of the technology to integrate such technologies with a traditional phone lines, though. You may look into Ribbit APIs as one solution. I was under the impression that Ribbit used Red5 under the hood; and it designed for these type of telephony applications.
You can use flex and Ribbit for that. Ribbit is a company that offers VOIP solutions for web application. I have used in couple of projects and it's really good.
Here is the link to their deve zone (htey support several technologies):

Hope this helps.
