Java :: Connecting Android App (with Flex) To Server Using Socket?
Apr 2, 2012
I'm trying to create an app that multiple users would log into a server hosted over the local network. When testing the app in Flash Builder it connects, but when I run it on my phone it does not. I'm using XMLSocket like so:
I have Flex/AIR app that connects to a tomcat server via BlazeDS. I'm not finding that I have to integrate an old webapp (struts/jsp) and I'd like to keep that webapp untouched except for login, authentication and session handling. Also a 3rd java app that uses httpclient.
Currently I have some blazeDS remote objects to handle login/logout with a few RPC calls. In turn, FlexSession objects are created and handled. Is there a way to use httpclient and javascript to call those blazeds RPCs so I dont have to recode and have 3 different means to handle logins and sessions?
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?
private SimpleServer(int port) { System.out.println(">> Starting SimpleServer on port " + port);
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?
I'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
I'm writing socket server in java for my flash browser based game and i need to connect to mysql database. Is it possible to connect to mysql through socket server and send received data to connected flash clients?
I am using a Socket (not xmlSocket) connection between flex applications and the server pushing messages.Now, when I connect from the local machine to the server everything is working file and running, connection is succesful and I get data back and forth.When I upload the application (flex) to the server and run it from there, I get a security sandBox violation message.Note:1. I do have a crossdomain file with * wildcard both on port and on domain.2. I created a Securiy.allowDomain("*") as well.Another thing.I also created another listener on that same server, listening to connections for port 843 (default) and this service just waited for a connection send policy file to the client and that's it.
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 created a Java REST service using Jersey. I use three of the HTTP "verbs" GET, POST and DELETE. I want to create several prototype front ends for the service. After much research, a lot dating to 2008 and 2009, I have been unable to find anything remotely simple.My three options are:
1) resthttpservice. This project hasn't been updated in a year. The only activity are one off suggestions that individual users have implemented.URL...
2) Create an AIR application. This isn't unfeasible.
3) Writing my own socket level code but there is a security restriction with flash players and I need to implement a policy server.
I have already read the question posted about asking whether using Flex for REST services were worth it. That information is old as well. I want to introduce REST services to my company but Flex's limited support for HTTP PUT and DELETE are discouraging. My service also uses the Accept header to determine if JSON or XML will be returned to the client. I can't seem to change HTTP headers without doing socket programming.Is there an easy way to use Flex 4 with RESTful services that uses PUT/DELETE and the Accept HTTP header?
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 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 am working on an Adobe Flex front-end with a Java back-end using JPA for persistence. he protocol I am using is remote objects (AMF) implemented with BlazeDS.I started out with a service-facade and entity DAOs, but without any specific DTOs. The same POJOs, the domain objects, were passed in the service-facade as those used as DTOs passed to the Hibernate DAOs.However, the latest few days I have been thinking whether this is a good approach or not. The latest article on the subject I read was this one:Interesting JPA Pattern blogThe situation:Say I have POJO Book with a unidirection ManyToOne relation with the POJO Category (i.e. each book may only be associated with one category, but the same category may be associated with many books). I see some alternatives:Alternative 1:I expose a method/operation addUpdateBook(Book book). In the implementation of this operation I add/update both the book and the referenced category.
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.
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?
We 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 have moved on now to where this is clearly a Flash security thing.I have a flash client that attempts to connect to an open socket on the same host as the one on which it lives.I am able to connect successfully from inside the Flash IDE, and when I run the swf movie locally on my machine, after granting it security clearance in the white list it connects as well. However, when I call the movie via the browser (URL...) it fails to connect.The socket reports that a connection attempt is made but immediately disconnects.I have a crossdomain policy file that looks like this: in the root directory of the host.[code]In the flash movie I have a line that looks like this: System. security. loadPolicyFile (URL...);And I'm thinking maybe that's where the problem is, but the documentation on how to use this method is not entirely clear. I'm in Flash CS3
I was just doing some testing using PHP sockets and Flash. I used several things, one thing is this tutorial:I have the server running, and when I run the swf via Flash it connects fine. But when I run it from the browser it can't connect.. Because that Tutorial is in AS2, I also wrote a quick client to connect with AS3, but I'm having the exact same problem.. it only connects if I run it through flash.Here's an example of the basic code:
Code: var s:Socket = new Socket('my IP', 5445); s.addEventListener(ProgressEvent.SOCKET_DATA, getData);
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. When I say server clients managing system, I mean a server which many clients will connect to and will be able to choose between tables to join and play or to create their own table, same way as in texas holdem poker.
I'm trying to connect to an FMS server with a Flex application. I can throw the rtmp URL straight in as the source for a VideoPlayer and it will work, but can't figure out how to get it to work with a NetStream. The pure Flash Video element works as in the FMS Flash demos, but is extremely laggy and lacks all the nice functionality of the built VideoPlayer. Is there any documentation on working with FMS with Flex? We're at a point where we need to decide quickly if FMS will do what we need to do or if we should purse other technologies.
I know it is possible to develop a full flex application using AIR for android but what I need is to embed a flex component into an already existing classic java android application.
I found some flash players in java but they all either require a JFrame or include of specific windows dlls.
The ActionScript 3.0 Reference says the following about flash.net.NetConnection:
The NetConnection class creates a two-way connection between a client and a server. The client can be a Flash Player or AIR application. The server can be a web server, Flash Media Server, an application server running Flash Remoting, or the Adobe Stratus service. Call NetConnection.connect() to establish the connection.
Does this mean I make a regular HTTP connection to any web server using an NetConnection object? I am a little confused about this as further down the section on the connect() method says connect(): Creates a two-way connection to an application on Flash Media Server or to Flash Remoting, or creates a two-way network endpoint for RTMFP peer-to-peer group communication....Pass an "http" URL to connect to an application server running Flash Remoting.. So, the application server has to have Flash Remoting?
I have a client-server multigame suite for PC ("kind of" cross-platform using cygwin), which is developed in Java(game menus and database management), C++ (server side), and adobe Flash (game graphics & interaction).
I have never tried to develop for android, so i have no experience.I am thinking of migrating this suite to google TV. So i would like someone with android experience to give a clue on the following :
1) Is it going to be easy to migrate the Java application to an Android application?
2) What kind of Flash support does Android have? Can it load directly swf applications? Does it have to load swf's through browser?
3) Can i find any kind of performance indexes for google TV hardware?
I want to test a simple PHP socket server with Flex, server seems to work fine when trying to test using telnet, but Flex doesn't display any responses, here's my code:[code]
I'm building a Flex application, which is going to perform many server requests (let's say, that almost all interactions require an update from server). At the moment I'm using remote procedure calls for it. But I was wondering if using a socket would be better. In other terms, is maybe better to keep the connection alive rather then performing many calls in sequence? For my demo app I only have 1 client. Is the number of clients connecting to the server a factor for this choice?
