ActionScript 3.0 :: AIR AS3 XmlSocket <=> Java TCP/IP Socket. 00 Byte In Wrong Place?
Mar 8, 2012I'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

Java :: Read An AMF Object With Flex Socket
May 18, 2011I'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";

Actionscript 3 :: Communication Between Flex And Java Socket?
May 19, 2011I 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?
Java :: Binary Socket And Policy File In Flex
May 17, 2010I'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.
Java :: Flex Socket - Can't Receive The Command From Server
Aug 20, 2010I 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.

ActionScript 3.0 :: Error With Java+Flex Socket #2048?
Apr 27, 2010i 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.

View 1 RepliesProfessional :: Android Hero Denies XMLSocket Or Socket Connection?
Jun 16, 2010I am trying to adapt an existing flash web chat application for the Android mobile phone and I am having this really annoying issue. The server is a custom based solution and can send back both binary messages or XML. So I can use either XMLSocket class or the Socket class to get data from the server. Everything works fine when deployed and I connect from the desktop but when I try it from the android mobile I get the infamous errors #2031, followed by #2048. Now the crossdomain.xml file is rock solid and works well for desktop. When the connect socket method runs I see that the server replies with the crossdomain file but I get the error when running on the mobile. Has anyone bumped into this? Is there some limitation from the mobile phone part. I wasn't able to find anything relevant for this issue, in terms of the phone not allowing Socket or SMLSocket connections
View 5 RepliesFlex :: Operator Console App - Listen Java Socket To Receive XML Data?
Jul 13, 2010We 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?

Java :: OpenPeak Flash App XMLSocket Security
Mar 12, 2010We're trying to create an app for OpenPeak. The Flash app will act as a client to a Java server on another computer on another domain.The Flash app client connects via XMLSocket. The Java Server uses ServerSocket to receive a request and send back a message.In order to trust the server, the Flash client needs a socket master policy file to tell it that the server comes from a trustworthy domain. According to an article on Adobe, when a connection has succeeded, the Flash client automatically requests the cross-domain policy or socket master policy file on port 843.Still, even when we implement it according to the tutorials and recommendations we have read, the Flash client continues to throw the following security error:[code]We've tried logging the policy file request during testing to see if there was any call made to port 843. There was not.Interestingly, even without a policy file, the Flash client still manages to send the first data message to the server successfully. It's just when the server tries to send back a reply that the entire thing hangs for about 10 seconds before the security error above is displayed.

Dec 1, 2009I'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?

Flex :: Actionscript 3 - Flex Socket And Erlang Socket Communication
Jun 29, 2011I'm creating a client-server game. My client is a flex based game, and my server is erlang server. At the beginning, when I test directly my flex client in flash player, I can establish a connection easily to my erlang server through socket connection. And both can exchange data with no problem. The problem rise when I deploy my flex app at Apache http server, and running it using a browser by calling [URL] my flex socket sends message requesting for a crossdomain policy to my erlang server. So I create an xml message that represent a crossdomain policy, and send it back to my flex app as a response for that request.
Yet still I can't establish any permanent socket connection between my flex client and my erlang server. I know this because I add listener on my flex socket that will modify its internal state to CONNECTED, if a connection between client-server has established.

AS3.0 :: Java - Flex - ArrayList Of Custom Java Objects Over BlazeDS
Dec 7, 2010Right away i just try to explain my problem: Using BlazeDS i got the following Javaclasses:
[Code]...
Then i got a Flex service class calling BlazeDS and executing the getCategories java method. Since Flash dosn't seem to understand typed arrays, the result from that method which i get back in flex is a simple array of untyped objects (the mapping dosn't seem to work here, even tought the class category exists in flex and has the same properties).
thats the first thing. but however, i'm converting the untyped objects manually into objects of the category.as class. the second thing is that categories have child-categories within the java object, which are also ArrayLists of the type category.java. the problem about that: my result event object only contains the first level of categories, looking into them the children are allways null. i dunno why they are empty, since they ARE part of the java object category.
and the third thing (the strangest by fast), you maybe noticed i named the properties of the category.java class strange, like idCat and nameTest instead of simply id and name. why that? because the property names of my flex result objects dont seem to change when i change the java objects properties names (result object properties are named "id" and "name" but the java class object properties are named "idCAT" and "nameTEST"). that it REALLY strange, since if i set the properties, like you see at nameTEST = "TESTNAME" it IS recogniced by flex, only the proertyNAMES dont seem to be recognized at all.
