Re: OpenAMF with AS2

 
Jason,
 
The problem you have is that standard objects cannot be sent from java to  
flash directly. You need to use an object called ASObject, which needs to be  
imported. I am currently using the macromedia gateway so the import function may 
 be a little different than the openAMF, but you should be able to find the  
definition in the openAMF project and import it as I show below. the second  
parameter of the ASObject.put routine can take simple data types or complex 
ones  such as resultsets. 
 
There is also a function called ASTranslator (find on google at souceforge  
or carbonfive) that translates any java object into a flash object.
 
I just figured all this stuff out yesterday, and the weird thing is that  
there is, as far as I can tell, no official documentation on ASObject (at least  
from macromedia or anywhere on the web), but lots of people seem to know how 
to  do it. I saw some example somewhere, but would love to find a full 
description  of all the methods and properties. I don't know how macromedia succeeds 
with  such poor documentation of such basic things.
 
Anyway, hope this helps.

uncompiled code example using ASObject ----------
 
import flashgateway.io.*;
 
class getPersonClass {
    public static ASObject getPerson  (){
ASObject  person =  new  ASObject();
person.put("firstName",  "sam");
person.put("lastName",  "smith");
 
      return  person;
}

}
 
-----------------------------------------------------------------------
Example of ASTranlator from carbon five-------------

package com.server;
 
 import flashgateway.io.ASObject;
 import com.carbonfive.flash.ASTranslator;
   
 public class Service
 {
   public ASObject getPlayer(String name)
   {
     Player player = Roster.getPlayer(name);
     ASObject aso = (ASObject) new ASTranslator().toActionScript(player);
     return aso;
   }
 }

Hi,

I tried to use OpenAMF with ActionScript2 using a simple  example.  The 
result displayed on the screen was "undefined  undefined".  JDK version used 
was 1.4.1.  I post the log, source  codes, and code scriptlet in the 
configuration file here.  Would  anyone help to figure out what went wrong?

Thanks in  advance!

Jason
