I read through the method to connect to a socket server : [URL]. I wrote an AIR application to connect to the java server code, but the client cannot connect. What is missing in the code?

I am writing a online game with flex and java server and I have a big problem. In normal case, my game run smoothly but some time the clients can't receive the command from server. I found that if server send message too fast or client is doing something when server send message, the game client can't detect for a new message so my game is freeze. I only tested with 4 clients and I don't know what happen when thousands clients online in the same time. So terrible :(. In the game client, I use one EventDispatcher class to dispatch any command from the server. Do you have any solution to warranty that client must receive any message from server when the connection is still alive or server must know if client received the message or not. I use flex 3 with Socket (binary) and Java QuickServer.

i want to know how to send data using the AMF format from my flex AIR project to a socket written in Java. I am getting CorruptedStreamException when sending data using writeUTFBytes() methods. Has anyone experienced similar problems? Also can AMF be used only if i am using LCDS only?

Ok, basically my Flex app will open up a socket and listen on it. My java program will write some string to this port.
My AS3 code is
private function onRecvClick():void
{
var host:String = "localhost";
[Code]....
While trying to write to the socket, i am getting this java.net.ConnectException: Connection refused: connect. Funny thing is that the socket in Flex doesn't seem to dispatch any events, is it normal for that to happen?

View 21 RepliesI have a typical Flex-based application that was written to use a Java/Hibernate/MySQL backend. The client changed the requirements - now they want to distribute it on a CD where the user can just run the app without any installation or a network connection.
To do this, I certainly need to eliminate the web server and the database server and adapt my application (with as few changes as possible, of course) to a stand-alone application that will fit on a CD/DVD. I've managed to export the data to XML and read it into Flex, but I'm wondering if there's a way to recreate the Hibernate data structures in Flex so I could change as little code as possible. Failing that, is there any way to keep the existing Java/Hibernate external to the Flex code but retrievable without installing Apache Tomcat or MySQL?

View 1 RepliesI'm trying to implement a binary protocol between a flash application and a Custom Java Server using TCP/IP sockets, the protocol's messages are of variable length, so my idea is to add a field indicating the number of bytes I have to read before parsing a complete message, something like this:[code]if while processing a message (supossing it is complete) other data arrives through the socket, are messages of type ProgressEvent.SOCKET_DATA queued so the number of times my handler is called is equal (at least in this case) to the number of messages arrived or should I read until all data the socket has available? or simpler: are in general messages for a handler queued in flash?
View 1 RepliesI'm currently trying to communicate between java and flex by using sockets and AMF serialized objects.
On the java side I use Amf3Input and Amf3Output from BlazeDS (flex-messaging-common.jar and flex-messaging-core.jar).
The connection is correctly established, and if i try to send object from flex to java, i can easily read objects :
FLEX side :
protected function button2_clickHandler(event:MouseEvent):void
{
var tmp:FlexAck = new FlexAck;
tmp.id="123456789123456789123456789";

I have a Flex AIR app, and i am trying to get data from a Java Server. Can some one tell me if this approach will work?
Start a ServerSocket in Java and wait for a connection. Use Flex to connect to the same port. Write some data to the socket from Java Server. Read the data at the Flex end and process it.
I think i am able to get this working, but the data that i read back at Flex end seems to be empty.
My server code is :
socket = new ServerSocket(port);
client = socket.accept();
InetAddress address = client.getInetAddress();
[Code].....
My current problem is socket.bytesAvailable becoming 0 and therefore obj is coming up as "". So how to read data sent from the server using a Socket in Flex?
I'm trying to evaluate whether Flex can access binary sockets. Seems that there's a class calles Socket (flex.net package). The requirement is that Flex will connect to a server serving binary data. It will then subscribe to data and receive the feed which it will interpret and display as a chart. I've never worked with Flex, my experience lies with Java, so everything is new to me. So I'm trying to quickly set something simple up. The Java server expects the following:
DataInputStream in = .....
byte cmd = in.readByte();
int size = in.readByte();
byte[] buf = new byte[size];
in.readFully(buf);
[Code] .....
After that - EOFException happens on the server and that's it. So the question is, am I approaching whole streaming data issue wrong when it comes to Flex? Am I sending the policy file wrong? Unfortunately, I can't seem to find a good solid example of how to do it. It seems to me that Flex can do binary Client-Server application, but I personally lack some basic knowledge when doing it. I'm using Flex 3.5 in IntelliJ IDEA IDE.
i got a problem with 'Security error',it happens when i try to connect my XMLSocket (Flex) with my Socket (Java)i have a domain:
alucardeck.mine.nu
i startup my apache tomcat 6.0 and in ROOT folder i have:
policyFile.xml and crossdomain.xml
(i had a doubt about what is the correct filename so i created both)both files contains:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />
</cross-domain-policy>
well, yes, you can access using the default port 80, as it should be.(but probably my server will be down when u try to access it)so here is what i do: i run my Java server application.there i open 1 socket in port 19809.(i already tried with port 843 too) then, i run my Flex application: [URL]also i tried to run it in ROOT folder..the XMLSocket class is instanced like this:
xmlsock = new XMLSocket();
// add all listeners
Security.loadPolicyFile("http://alucardeck.mine.nu/crossdomain.xml");
// also tried "xmlsocket://alucardeck.m....
[code]....
i also notice when i start my Java Server application with 2 sockets listening ports: 843 and 19809, i notice Flex first try to connect to 843 and then 19809, and in both sockets i reply with that String from before.
I'm sending through a socket from java to flex client some data and the flex side can't seem to handle it right. In the java i'm looping over 8 objects and for each object I create a long string 1:lsls:2:3:justexample then the java does writeToSocket("1:lsls:2:3:justexample") for every iteration of the loop. But in the client side, it seems that only 2 out of the 8 arrived. what can be the problem?
View 1 RepliesI'm extending XMLSocket to work with a daemon, written in Java, that a peer is using to interface with his PLC controller.What I should be seeing from the daemon is simple digital io info in the form:
Code:
d0i,d0o,
Which represents a 'button' dowm/up. The strings are terminated with commas to make it easier for me to parse them. I've got my XMLSocket working just fine, but I'm receiving the data more like this:
Code:
socketDataHandler:
socketDataHandler: D
socketDataHandler: 4
[code]....
So, there's a null character, followed by individual chars that make up the message I'm expecting, only last "," is truncated. It does come through on the next dataEvent:
Code:
socketDataHandler: ,
socketDataHandler: D;
socketDataHandler: 4;
socketDataHandler: O;
Lastly, I checked raw data in a shell, and it looks like:
Code:
0000000: 0044 0034 0049 002c 0044 0034 004f 002c
0000010: 0044 0034 0049 002c 0044 0034 004f 002c
When dumped to hex. It is my understanding (mostly from a sdocs) that Each XML message is a complete XML document, terminated by a zero (0) byte.I can see that he's sending each CHAR separated by a 00 byte, but they are prepended, not appended like:
Code:
0000000: 44 00 34 00 49 00 2c 00 44 00 34 00 4f 00 2c 00
0000010: 44 00 34 00 49 00 2c 00 44 00 34 00 4f 00 2c 00
or even better:
Code:
0000000: 44 34 49 2c 44 34 4f 2c 00
0000010: 44 34 49 2c 44 34 4f 2c 00

View 2 RepliesWe are in the middle to evaluate the technology choice to re-design an operator console application. The operator console as a hosted contact center has the abilities to queue the inactive calls, and hold, answer, transfer the active calls.
The legacy operator console used Java Swing. We want to use the latest RIA technology (Flex/Silverlight) to retire the legacy one. But the question is Flex/Silverlight can implement the functions like hold, transfer the calls? Based on my experiences, Flex can listen Java socket to receive XML data? Does it work well to receive voice data?
I'm building a Facebook multiplayer game where the client side is in FLEX and the server side is in Java and I wanted to know if there is a guide on how to build the server clients managing system.

View 2 RepliesI'm working on a flash MMO with a c# server. I have a simple messaging protocol for the sockets. When a client joins he sends out this:

I am writing a game where positions of an object are being exchanged between the two flash clients through a java server. The secnario goes simply like this:
PlayerA ---> Server : "Position X + Position Y+
"
Server ---> PlayerB: "Position X + Position Y+
"
and it works both ways of course.the problem here is that on my computer where i use "localhost" everything is fine and the data is exchanged seamlessly .. when I loaded the server on a remote host the message received strangely turns into something like "Position X + NaN" (i.e. the y position is wrongly parsed by the server), what is weird even more, is that sometimes, the message gets parsed correctly..the server is wrote in java and it is exactly the same source code that works on my machine that fails over the internet
is it possible for me to build a server in java so that i can let my different flash clients communicate with each other?
