[Flashcoders] json flash 8/9
Hi, I'm currently involved in a project, where webservices are being accessed from flash, through a 400kb microsoft javascript library. The developer claims it is webservices through json, which is supposedly done because of the big performance improvement. All I see is a 400kb javascript overhead for something flash supports natively and locks up my browser. Anyway, another thing is they claim the content (created in flash 8) has to be run in the flash 9 player since there are 'issues' with JSON in Flash 8. So my questions to you folks are: - does n1 know of a good reason to use webservices through json through javascript in flash - are there any known problems using this approach in flash 8 And some good sources on json in flash would be nice, ofcourse I've been googling, but there are a LOT of hits. regards, JC ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Hi, thanks but I forgot to mention its AS2, will I need the additional libraries there? (they argue its as2 that has to run in fp9, go figure ;)) regards, JC On Fri, Aug 22, 2008 at 4:17 PM, Eduardo Omine [EMAIL PROTECTED]wrote: On Fri, Aug 22, 2008 at 9:49 AM, Hans Wichman [EMAIL PROTECTED] wrote: - does n1 know of a good reason to use webservices through json through javascript in flash Some developers prefer JSON over XML.

Hello :) You can use my opensource framework with this JSON class : http://code.google.com/p/vegas/wiki/VegasTutorialsString_JSON http://www.ekameleon.net/vegas/docs/vegas/string/json/JSONSerializer.html To install VEGAS : http://code.google.com/p/vegas/wiki/InstallVEGASwithSVN PS : if you use only the AS3 version of VEGAS you can use the branche : http://vegas.googlecode.com/svn/AS3/ Now... JSON is good but the eden format is BETTER ! eden is in the core library of VEGAS in AS3 (see the system.* package : ) See the official page project of eden : http://code.google.com/p/edenrr/ See the features of eden : http://code.google.com/p/edenrr/wiki/edenFeatures In VEGAS you can use two class EdenLoader and JSONLoader (based on the URLLoader class) who load a JSON or eden external file and parse it : JSON : http://www.ekameleon.net/vegas/docs/andromeda/net/JSONLoader.html eden : http://www.ekameleon.net/vegas/docs/andromeda/net/EdenLoader.html You can see an example of config file in eden in the examples of VEGAS : http://vegas.googlecode.com/svn/AS3/trunk/bin/test/andromeda/net/deploy/data/config.eden See the difference with the same JSON config file : http://vegas.googlecode.com/svn/AS3/trunk/bin/test/andromeda/net/deploy/data/config.json You can see too my Localization model and config model in the example of the extension AndromedA : http://vegas.googlecode.com/svn/AS3/trunk/bin/test/andromeda/config/ http://vegas.googlecode.com/svn/AS3/trunk/bin/test/andromeda/i18n/ If you want optimize your work flow.. you can use eden too with my a full IoC application library in AndromedA, all examples in the repository : http://vegas.googlecode.com/svn/AS3/trunk/bin/test/andromeda/ioc/factory/ With my IoC framework you can create a big application with external eden configuration files, example : http://vegas.googlecode.com/svn/AS3/trunk/bin/test/asgard/net/deploy/context/hello_world.eden More information about it for the moment in french but the english tutorials coming soon ! http://groups.google.com/group/vegasos/web/design-pattern-dinversion-de-contrle EKA+ :) 2008/8/22 Eduardo Omine [EMAIL PROTECTED] On Fri, Aug 22, 2008 at 9:49 AM, Hans Wichman [EMAIL PROTECTED] wrote: - does n1 know of a good reason to use webservices through json through javascript in flash Some developers prefer JSON over XML.

Re: [Flashcoders] json flash 8/9
With AS2 I'd recommend using Flash Remoting with AMF (binary format). AMFPHP is the most well-known AMF solution, but there are AMF solutions for Python and Java too (and probably other server technologies). http://www.amfphp.org/ http://pyamf.org/ http://sourceforge.net/projects/openamf/ And yes, you need an AS2 library to parse JSONs too. http://www.5etdemi.com/blog/archives/2006/05/cinqetdemijson-a-better-json-parser-for-as2-suited-for-config-files/ -- Eduardo Omine http://blog.omine.net/ http://www.omine.net/ ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] json flash 8/9
With VEGAS you can work in AS2 or AS3 :) And for remoting : http://www.ekameleon.net/vegas/docs/asgard/net/remoting/RemotingService.html the class asgard.net.remoting.RemotingService work in AS2/AS3 and SSAS (Server Side ActionScript for Flash Media Server) EKA+ :) 2008/8/22 Eduardo Omine [EMAIL PROTECTED] With AS2 I'd recommend using Flash Remoting with AMF (binary format).
