Actionscript 3 :: Handshake With Html5 Websockets?

Mar 14, 2012

I'm trying to build a AS3 socket server that can handshake with html5 websockets. I've base my code on this link http:[url]....This is what i have using the same values as the example in the link:

import com.dynamicflash.util.Base64;
import com.adobe.crypto.SHA1;
function getKey():void{[code]...

Now the example states that the output should be : Concretely, if as in the example above, |Sec-WebSocket-Key| header field had the value "dGhlIHNhbXBsZSBub25jZQ==", the server would concatenate the string "258EAFA5-E914-47DA-95CA-C5AB0DC85B11" to form the string "dGhlIHNhbXBsZSBub25jZQ==258EAFA5-E914-47DA-95CA-C5AB0DC85B11". The server would then take the SHA-1 hash of this, giving the value 0xb3 0x7a 0x4f 0x2c 0xc0 0x62 0x4f 0x16 0x90 0xf6 0x46 0x06 0xcf 0x38 0x59 0x45 0xb2 0xbe 0xc4 0xea. This value is then base64-encoded (see Section 4 of [RFC4648]), to give the value "s3pPLMBiTxaQ9kYGzzhZRbK+xOo="

Javascript :: Client Technology Choice - Any HTML5/Canvas Libraries As Capable As Flash/Flex?

Jan 7, 2011

I built a prototype in Adobe Flex, they (customers) liked it. Everything was fine until they later told me that iPads / iOS needs to be supported too.I checked out Adobe's Packager for iPhone. We're evaluating that and we will know if it works out in a couple of days. (We need to get through Apple's red tape and certificates raj so this angle is delayed by a few days!)

There is a growing voice for using HTML5/Canvas as a technology platform itself. And despite being quite proficient in Flex, I think this makes sense.

I'm in need of a HTML5 library that can:

Render "widgets" i.e. containers with forms and components(this should be easy and possible using POHJC - Plain old HTML,JavaScript and CSS )Provide a Tree like control for laying out some data Provide a Canvas where data structures can be represented as basic shapes Provide drag and drop capabilities between Trees, Buttons and Canvas Provide some sort of Tab Navigator container (I guess JQuery works here) Interact with back-end services (JSON/XML calls will be okay, but mapping directly with back-end entities will be awesome!)Renders on latest versions of major browsers, Android OS and iOS (WebKit for mobile?)

I'm ready to give JQuery & JQuery UI a try. I looked at Sencha / ExtJS but it seems we need to maintain two code bases one for normal browsers and the other for mobiles (is that correct?)Single code base, I don't want to suggest to them that multiple code bases for the client need to be maintained. That's a last resort option and would lead to complete ruling out of HTML5 with Flash apps and native apps being developed.Canvas capabilities - I don't want to work with raw canvas and shape tags. This too is a last resort option. Is there any abstraction available?

Flex :: Can Enterprise Apps Requiring HTML5's New Feature(s) Support Non-HTML5 Browsers

Nov 16, 2011

I'm just trying to understand how once HTML5 enters the picture, the current concerns about browser incompatibility and other issues go away? Wouldn't HTML5 simply add another set of browsers to the large list of current browsers that the application must target?

That is, assuming the enterprise web app requires one of these new HTML5 features (e.g. playing audio and/or video, integrating SVG or vector graphics, etc.). If such a feature isn't critical then graceful degradation may be acceptable and then my question is moot.

But for those apps that require one of these new HTML5 features, are you planning to support older browsers, or expecting it's acceptable to restrict to HTML5 browsers because the enterprise in question has made one of them their new corporate standard (or other scenario, etc.)?

Flash :: Java - WebSockets Fallback And Jetty 8?

Mar 20, 2011

I found this awesome example: [URL], or an HTML5 WebSocket echo server in Jetty, and I love it's simplicity. However, the web app I am developing will require a bit more cross-browser compatibility, so I tried to use: [URL] as a Flash fallback. The problem: I need to serve some XML file on port 843 for Flash. Now I am new to both Flash and Jetty, and would like to figure out how to accomplish this. I have used HTML5 WebSockets before in PHP, Python, and Ruby, and I have the echo server working perfectly on my Mac, but now I need to configure Jetty to send the file.

Framework Similar To Adobe Flex With HTML5?

Dec 28, 2011

is there a framework that is similar to Adobe Flex written in HTML5? My app currently support having multiple objects on the screen where user can drag / drop / resize and rotate them in scrapbook fashion. There are few animations as well. Flex makes it easy to build such apps. I was wondering if there is a good framework I can use to ease up such task maybe with HTML5 so it can be used on mobile devices.

Javascript :: Flex Vs JQuery Vs GWTvs / Closre Vs Cappuccino Vs Plain JS And HTML5?

May 19, 2010

I'm creating my first web application and I'm really confused as to what technology to go for. My application needs to look serious (like an application), it doesn't need many colorful graphical interfaces. It only needs a toolbar, a tab bar, a split panel (preferably 3 columns), an easily-formatable text field, and a status bar. It will connect to a MySQL database through PHP (unless I go for GWT). Users will upload files. My evaluation of the options:

Flex: Probably the easiest to develop but I'm pretty sure my application is something one would use on an iPad and with Flash's future on the iPad still unsure, I don't want to take the risk, otherwise Flex would've been my choice. jQuery: I've heard a lot about it and a lot of people recommend but I don't know how easy it is to use and how customizable the look of my app is. GWT: The problem with GWT is that it doesn't have many widgets. Another problem is that I'm gonna have to host the files in AppEngine's datastore and transfer them back and forth to a web server that will do operations on them (I need to process them) which adds more traffic and slows the process which worsens the user experience. Closure: It has a nice toolbar and a nice text field. I'm not sure how easy it is to use. Plus, I read an article that makes it sound really bad.

Flex :: Debugging - Running A Webapp Base Flex Client In IntelliJ?

May 10, 2011

Is it possible to run a Flex client in IntelliJ internally and have it talk to a separately deployed server instance? The server's a java webapp. This will make developing, especially debugging, much easier. What I'm trying to avoid is having to rebuild and redeploy the webapp to get the updated Flex code in it. I want to just build flex and run it against the server.

The flex client is embedded in an HTML page on the server, so in production the users access the client by going to a web page. We're using GraniteDS if that's important.

Update

I'm managed to cobble something together, but it's ugly.I made a copy of our wrapper HTML page and fixed the links to refer to the SWF in target.I setup the IntelliJ run config to point to that HTML page.I set the 'Place SWF file in a local-trusted sandbox' to true

Hardcoded the {server.name}, {server.port}, and {context.root} values in the service-config.xml GraniteDS config file to localhost, etc.

I can mavenize #1, but #3's isn't really a permanent solution. That part is still a problem because I can't check this in.

Flex :: Adobe Flex - Doing Group By At Client End (DataGrid To Pie Chart)?

Dec 23, 2010

I am in a situation where user gets the cars data from the database based on the selection and displays it in datagrid like below ( for example)

Company Model Year No
GM Chevy 2010 10
GM Chevy 2009 5
GM Pontiac 2010 12
Honda Civic 2009 12

and there will be a link next to datagrid to get Pie chart based on the data displays in the data grid . The pie graph should display grouping by company and the count . I mean for the above example that should give with two pie items , one for GM showing the number of vehicles ( in this case 3 ) and Honda showing the number of vehicles ( in this case 1 ).

I thought of getting it from the database by querying and grouping it .But here the problem is after getting the data above in the datagrid user can able to filter at client end ( By year or model ) and can say get graph . This time that should only display the graph for the data visible in Datagrid .Grouping on database for every operation is becoming expensive. Since we have already data available at client end , is there any way to group it at client ..?

Flex :: Generate Flex SOAP Client Using Maven?

Aug 9, 2011

I have a java server side project which contains JAX-WS web-services (using JavaEE 6 and the @WebService annotation).

Is there some kind of plugin that would allow me to generate Flex client stubs during my maven build ?

I have taken a look at enunciate, but it seems to generate only AMF client.

I've also tried to look at GraniteDS, but their doc seems a little opaque to me.

Notice my Flex project is compiled using flexmojos, which contains a flexmojos:generate mojo that should be able to generate domain object (however I don't understand how to say it to use domain classes from ANOTHER project, and not from a different folder).

So, is there any maven plugin that would allow the kind of feature described in this Adobe page ?

Flex :: Will MXML Ever "compile" To Html5

Jan 9, 2011

I�m using flex with Ruby on Rails backend to develop rich internet apps. Recently flash has been attacked, an example is Steve Job�s thoughts on Flash.

I think flex is a wonderfull tool, but to be honest I really would rather to have a tool as productive as flex but compliant with open standards.

For me, in a perfect world I would code in MXML just like I do now and Flex Builder would build a pure html5 front-end.

Php :: Bundling PHP MySql With Flex To Be Given To A Client?

Aug 1, 2009

I made an application using Flex,php,mysql. Now to give it to a client, I am bundling this flex application with xampp. There are few problems with this approach :

1. Whenever the flex application runs, an xampp window also opens up.

2. The Apache port number, which I am giving to the client is fixed. Same for mysql port number.

What could be a better alternative to overcome these?

Flash :: Flex - Do Sessions With A Client

Jan 28, 2010

Since the Flash Player (or, more exactly, the URLLoader class) will not let you read HTTP response headers or cookies set by the server, and if you get hold of a session cookie through some workaround like reaching out to the browser and run JS, you can't send it to the server, because, among others, the Cookie header will be blocked. Now I'm building a Flex client against an HTTP API for my server product. I control both sides, so I can get get around the above limitations, now I'm wondering how. I see the following options:

include the session token in the HTTP payload include the token in the URL build my own HTTP client (... with blackjack, and hookers ...) in AS, using the Socket class I don't like (1), because I'm reimplementing functionality in my protocol that is already built into Struts, which I'm using to implement the server side. I then have to ensure that either both behave the same way, or turn off the usual way of session management and force other clients to use my protocol where they could just have the browser deal with it. I don't like (2), because I understand that there are security concerns with this, although I'm not too sure which

I don't like (3), because it's 2010 and tons of HTTP clients have been written by smarter people than me. So, are there other opportunities? Which of my "don't like"s do you reckon least severe? Are there ways to mitigate the problems I listed? For example, how insecure are session tokens in URLs really?

Flex :: Use Dto's To Transfer Data Between Server And Client?

Oct 28, 2009

I've read some books on creating stateless websites, I've read some about stateful client applications, but a lot of complexity comes along when you have to combine both. We have a Flex application that needs to persist data to a database via .NET services. Things to keep in mind are:

- Concurrency (optimistic/pessimistic)

- Performance: Flex needs to load in lots of data so lazy-loading is often necessary.

- Do you use Dto's to transfer data between server and client?

I'll tell you the history of our product. We've used SubSonic from the beginning as a o/r mapper. SubSonic objects are converted to dto's written by us and these dto's are transferred to the client. Clientside the dto's are converted to the domain model. If clientside a domain model object needs to be saved, it is converted back to a dto and send to the server. Server side the dto is converted to a subsonic object and saved to the database.

Now, some time ago, we needed the domain model on the .NET server side... so now we have like three models on the server side, the subsonic model, the dto model and the domain model. The dto model is more simple and resembles the database more, the domain model has much more logic. It gets complex... We now have to synchronize the AS3 domain model code with the C# domain model code. If we could do it again (of get time to refactor) I think we wouldn't use the dto's anymore, but transfer the domain model between client and server. Dto's are simple objects so easy to transfer. Domain model objects can be very complex.

Flex :: When Mapping Inheritance In Web Service For A Client

Dec 1, 2009

I have an issue when consuming a web service from a Flex app. In the backend I have a hierarchy, let's say I have an abstract class Fruit, and 2 implementations: Apple and Orange. Fruit has a property, name, Apple has a property color, and Orange has a property radius. Then, I have a service wich returns a collection of Fruit. When I consume it from Flex, this collection returns objects wich type are Fruit, with its name property; but I lose all the properties for the implementation classes (color nor radius). So, the question is, does Flex support inheritance mapping when using web services? If not, is there any workarround?

Flash :: Push Data To Flex Client?

Mar 14, 2010

I want to push data to flex clients. I am talking about anywhere between 5000-15000 concurrent users, need to get data every time a currency is changed so that means lots of changes for lots of users.

I have been looking into WebOrb.net, but the performance seem very poor (100 users concurrent) for a product so pricy (we purchased a license).

So, I have to look into alternatives, I know there's fluorineFx but it seems no one is really using it for products and it lacks in examples and documentation.

My question is: what products can answer my needs (.net backend) and what are the performance I can expect out of these products?

Flex :: Client / Server Messaging (RPC Or Socket)

Apr 9, 2010

I'm building a Flex application, which is going to perform many server requests (let's say, that almost all interactions require an update from server). At the moment I'm using remote procedure calls for it. But I was wondering if using a socket would be better. In other terms, is maybe better to keep the connection alive rather then performing many calls in sequence? For my demo app I only have 1 client. Is the number of clients connecting to the server a factor for this choice?
