View 1 RepliesJava :: 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.

Nov 15, 2010I'm using a binary socket to talk to a server and it works fine the first time I send data. Then I receive data from the server and send a response but it's never received... like the connection closed or something. I have an event handler on the socket close event, but it doesn't fire. I can trace to the socket sending data, but if I trap the data received event on the server, nothing is received.. like it's closed the socket. Is there something I need to reset or have I missed a key concept in binary sockets?

View 1 RepliesActionscript 3.0 :: Connecting To A Ftp Server With Binary Socket?
Dec 30, 2008I'm trying to make a little ftp upload app - not a full FTP client, just something to enable image upload with decent performance. I basically took the approach Lee used in his POP3 socket tutorial. The problem I'm having is that I can connect to the FTP server and I can authenticate and log in but as soon as I try to enter passive mode for data transfer I get nothing- not even an error. From looking at the FTP RFCs, FTP requires two TCP connections - a command connection and a data connection - does this mean that I need to open a second socket for the data transfer? Another possible issue is the Flash Player security policy not allowing conection to ports under 1024 - I have not placed a policy file or policy server on the host running the FTP server but as I can successfully login, I appear to be able to connect to port 21 (standard FTP port) anyway. The code I'm using is:
Code: Select allvar s:Socket = new Socket("ftp.actechnology.co.uk",21);
var ftp_response:String;
s.addEventListener(ProgressEvent.SOCKET_DATA, receiveReply);
s.addEventListener(IOErrorEvent.IO_ERROR, showError);
[Code].....
why passive mode kills it or has successfully connected to a FTP server with the socket class
ActionScript 3.0 :: Binary Socket Policy File On Server
Jan 15, 2009I am attempting to setup a binary socket connection between flash running on my desktop and a Rabbit RCM3800 Microcontroller providing the server on my home network, which has no file system and has a very basic http server on it. Due to limitations of the microC I cannot run Java/Perl/Python or any other server on it other than setting up a server using its own native Dynamic C language (essentially manually opening and controlling sockets in C). I am able to successfully connect to a socket on port 3333 of the server and transfer information between the server and the .swf file when it is the sandbox type "local-trusted" (while I'm debugging in Flash).
Because of this I'm fairly certain the code to setup the socket between the server and flash works fine. My problem occurs when I try to run the .swf file as "local-with-network" (such as running it after publishing on my desktop) or "remote" (accessing the .swf file when it is located on the server) and it then requires a socket policy server to host a socket policy file on the server. On my server I have code setup such that whenever a socket opens on port 843 or port 3333 (my data port) and sends a stream of raw data containing the request <policy-file-request/>, the server writes back in ASCII the below code and closes the socket.
Code:
Select all<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "[URL]">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" to-ports="*" />
</cross-domain-policy>
[Code] .....
So for some reason flash times out while waiting for the socket policy file. I have tested sending the <policy-request-file/> over telnet, and have received the above policy file. I have also sniffed using wireshark and saw that my desktop sent the policy request and received the policy file. I am guessing that Flash times out because it is waiting for some kind of terminating character that states the end of the policy file, and to that end I have tried sending. Interestingly, instead of sending the policy file I have tried sending random data from the server to flash, and flash displayed the Warning: Ignoring policy file at (URL) due to incorrect syntax. Because I don't receive this warning when I send my policy file I don't think it is formatted incorrectly.
I have also tried using the below flash code to hold the socket request open indefinitely, but it also errors after 20seconds.
Code: Select allSecurity.loadPolicyFile("xmlsocket://192.168.1.59:843");
The .swf file will eventually reside on the server itself at 192.168.1.59/myProg.html. I have only tested the flash file remotely on the server a couple times, and in addition to the previous warnings/errors, I received the warning: SWF from (URL) may not connect to a socket in its own domain without a policy file.
ActionScript 3.0 :: Binary Socket Connection Interruption / Bytes Lost?
Jan 11, 2011I am starting with a short introduction: I am currently working on a project, which involves a server application written in .NET (C#) and a flash gui app as client (standalone flash player 10 [code is written in Actionscript 3.0]). The server constantly sends bitmaps to the client (up to 30fps). The connection is established using binary sockets and data ist streamed to avoid socket open/close/reconnection problems.The bitmaps sent to the client are marked with begin- and end-tags. A length field was added as well, to optimise the following parsing process. The client buffers the received data up to the point where an end-tag is found. The client reassambles the bitmaps on the screen by parsing the current buffer. Parsing means looking for begin-tags and length fields and/or end-tags of pictures packages. The resulting bitmap data is copied into a byte array and will loaded into a movieclip using the flash.display.Loader class ( bytePictureLoader. loadBytes( byteArray ); ).[code]While testing, I found out that in some cases the data stream becomes currupted, i.e. data is lost and/or the transmittion is incomplete.
A good thing is that this error is reproducable.It seems that as soon as the Flash Application Window is dragged (moved on Windows Desktop) the stream lacks data. The same error occurs, if too much data is sent to the client. The results are performance problems, data loss and other strange effects. The more data is sent on the stream, the more data has to be parsed and the more data gets lost somehow. Sometimes this leads to a memory problem, because Begin- and End-Tags aren't transmitted correctly. In order to fix (counteract) that, I discard data as long as there is no Begin-tag found and the buffer is cleared when the size exceeds 1Mb.It works so far, but the application lacks performance and stability.I.e. If 20 bitmaps per second with 620x390px are sent to the client, the client only receives 16 to 17 bitmaps, if the application does nothing else.If 30 bitmaps per second with 620x390px are sent to the client, the client only receives about 20 to 21 bitmaps.I am guessing that using actuall video streams would be better, then sending one bitmap at a time in a byte stream.Is there a proper example on how to build a client app in flash to receive/parse a binary data stream?Does anyone else has recognized the lost-data problem or the interruption of streams?

ActionScript 3.0 :: Socket Sending Policy-file-request Twice?
Dec 8, 2009Running my Flash app from localhost (in debug) I can connect/contact the socket server just fine. Note: It doesn't seem as though the server detects any 843 connection (e.g. the policy file port) this way. However, when I move the app to the server itself and run it from there (i.e. from the website), it will send the policy file, get a disconnect (as it should), and then try to execute the regular port stuff but doesn't read anything from Flash. It seems like my Flash app isn't writing to the port as it should, or something else is going wrong. I did also notice that Flash seems to be trying to send the policy-file-request twice.My process right now is like this:
1) Flash tries to connect to port 843. The server responds to its <policy-file-request/> with the policy file.
2) Flash reads it, disconnects from 843
3) Server gets graceful disconnect, then gets another connection on 843.
4) Just after that, the server gets a connection on 2188, but reads another <policy-file-request/>, so sends the policy file again.
5) At this point, Flash SHOULD simply write the string "Test" to the socket (that's in my connect handler). However, my server doesn't seem to read anything on the socket after the second <policy-file-request/>.[code]
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.

View 1 RepliesActionscript 3 :: Object Initialization Occur When Deserializing Binary Objects In Flex?
Sep 3, 2009The jist of what I'd like to know and focus on understanding, is details on how binary deserialization occurs in Flex 3. When is the constructor called, when are properties set, are private members serialized or does all deserialization occur on and through setters, etc? I'm having a hard time finding information on this.In a Flex 3 AIR application, I have a pretty complex object graph(just a bunch of objects referencing one another, kinda like a big data model except a bit more complex) that I serialize to a file using a single call on the FileStream.writeObject and readObject on a root object, which serializes and deserializes the entire object graph.I found that I needed to always have a default constructor, else I would get exceptions on the objects when deserializing if they were part of an ArrayCollection. So I had to eleminate the constructor parameters or set default values. I now have many setters like this in my classes, such as the below where mConnection accumulates some information it needs through different setters, where as before I had this all packed into the constructor since all of the information is really necesary for the Connection to function:[code]So the connection's serverIP is still an empty string because the server was assigned to the client's property before the server was completely initialized.
I could probably resolve this by using binding so that updates to the serverip in the server are bound to the connection, but I find binding properties to be fairly complicated (it's really simple on UI in mxml cause you just use the curly bracket syntax but doing it by code is what I found complicated). I have also resolved some cases by removing the constructor parameters entirely, so that there is no default values. All that aside, I still really need a deeper understanding of the details of binary serialization as far as how it rebuilds the object graph. I even have circular references, and it seems to handle those fine and maintain multiple references without duplicating objects. It's just when my constructors/setters are more complex that I'm running into these problems because of the order of what occurs during deserialization. It is really inconsistent though, as adding breakpoints in various places seems to influence the order that things occur, making it more difficult to debug.On a side note for anyone that might sidetrack the topic because I am serializing a class called Connection. I added some code to address some things, like in the Connection class there is an instance of a Socket. Of course my socket would not be connected after I close and reopen the application and deserialize it, so before I serialize my object graph, I go through and close the socket and set the reference in the Connection class to null, so that there is no longer a reference to the socket and thus it will not get serialized. After deserialization on the next application run I create a new socket.
