flex - File() FileStream in web app -

i've made desktop app, , want work web app. errors on lines file() type , filestream, there way bypass ?

to piggyback on @florian f's correct response, here how might implement it:

create interface abstract file access

public interface igetthestuffservice {     function getsometofu():tofu; } 

create file-based implementation

public class filestuffservice implements igetthestuffservice {     public function getsometofu():tofu {         // file-based implementation     } } 

and http-based implementation

public class httpstuffservice implements igetthestuffservice {     public function getsometofu():tofu {         // http-based implementation     } } 

in consumer, rely on igetthestuffservice

[inject] public var tofuservice:igetthestuffservice;  public function dosomestuff():void {     var tofu:tofu = tofuservice.getsometofu();     // act on tofu } 

notice inject meta tag. dependency injection (di) system push in dependency based on configuration (filestuffservice air apps or httpstuffservice web apps). parsley , robotlegs use [inject] fiex-ioc uses [iocbind]

of course, go without di container... inject parameter directly.

but idea... pretty simple pattern, actually.
