Hi.
How do i receive flash objects in java?
I'm trying to create a multiplayer game, i've chosen sockets to handle this and Java as the server. So far i made myself a client/server already. And it works when sending as3 objects. but, not the way i want it!
I made a class in AS3 and in Java that represents the object to be sent.
AS3 Class 'Package'
PHP Code:
package com.myapp.pck {
import flash.net.registerClassAlias;
import flash.display.Sprite;
import flash.utils.IDataInput;
import flash.utils.IDataOutput;
import flash.utils.IExternalizable;
public class Package implements IExternalizable {
public var cont:String = "test";
//constructor
public function Package(){
registerClassAlias( "Package", Package );
}
//getsetters here
public function readExternal(input:IDataInput):void
{
cont = input.readObject() as String;
}
public function writeExternal(output:IDataOutput):void
{
output.writeObject(cont);
}
}
}
And the Java Class 'Package'
PHP Code:
package myserver;
import java.io.Externalizable;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectOutput;
public class Package implements Externalizable {
String cont;
public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException
{
cont = (String)in.readObject();
System.out.println(cont);
}
public void writeExternal(ObjectOutput out) throws IOException
{
out.writeObject(cont);
}
}
With flash i simple send the object (Note that this isn't the complete code)
PHP Code:
//init blabla
socket:Socket = new Socket();
p:Package = new Package();
//send
p.writeExternal( socket );
socket.writeUTFBytes("\n");
And java receives it with
PHP Code:
//java
out = new PrintWriter(socket.getOutputStream());
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String line = ois.readLine();
while(line != null){
//get input here
}
I receive the Object (serialized string actually) just fine and i can send it right back so flash can reconstruct an object out of it again. but here is the problem:
I want to access the object in java, edit it, and send it back, but if i even edit the raw serialized string, flash will not read it anymore.
so my goal is to 'import' the flash Object structure so i can access every variable in Java.
I tried using
PHP Code:
oos = new ObjectOutputStream(socket.getOutputStream());
ois = new ObjectInputStream(socket.getInputStream());
instead of the PrintWriter or BufferedReaded but no luck there, Because the ObjectInputStream can't read the serialized string and returns with a "Invalid stream header". Even when i pass the string right to the Package class method:
PHP Code:
Package p = new Package();
p.readExternal(ois);
I tried google alot, but i dont seem to find anyone that shares my problem.
Thank you.
I wasnt sure in which forum to post, because it has a bit of everything heh. Sorry if this is the wrong one"
