HTTP socket connection
Hi,
I have an applet which communicates with servlets, sending serialized objects back and forth. This works fine but it means communication between client and server can only be instantiated from the client side. It would be better if my applet (or possibly client application) kept a connection with the server that enabled the server to send messages to the client.
Presumably i would use sockets to do this. The problem with that may be that i need to be sure there will be no problems with firewalls etc.
Could anyone tell me if it is possible to get the sort of two way communication i am after using HTTP, or maybe HTTPS(presumably this is normally open)?
Any suggestions would be most appreciated
You cannot use the HTTP connection that downloaded the applet for further use.
You get the applet to send HTTP requests and POST serialized java objects/receive serialized java objects.
You can get the server to open a connection to the client, but increasingly many clients have their own firewalls which will block this. Since you control over your firewall but not theirs this is a bad idea.
Firewalls can cause some issues with custom socket solutions, if you cannot use the HTTP protocol, I would suggest connecting port 443 normally used for HTTPS. You need to ensure this does not go to a real HTTPS server but instead your application. This has the best chance for success with both firewalls.

Socket Connection Vs HTTP connection
I'm trying to get a better understanding of which to use to connect a midlet to a servlet.
Does anybody know of any advantages socket connections have over http connections i.e performance or anything you can think of? Or is there any reason http connections seem like better practice for this type of communication (servlet-midlet) besides portability across MIDP
I'll appreciate your opinionsHTTP is a particular kind of socket connection. If what you're doing is plain old HTTP, then HttpConnection is easier to use. If you need something more than HTTP, then use SocketConnection.

Socket connect slow in JDK 1.5?
We recently began testing our Java Swing application with JDK 1.5, and we noticed that socket.connect()
calls are taking several seconds to return, when before in 1.4 the calls returned immediately.
Here is some sample code:
Socket sock = new Socket();
InetSocketAddress sockAddr = new InetSocketAddress(inAddress, portNum);
sock.connect(sockAddr, 2000);
What could be wrong? I've debugged the code and verified inAddress is an IP address,
not a hostname.
-EricHere is the list of enhancements in JDK1.5.
http://java.sun.com/j2se/1.5.0/docs/guide/net/enhancements-1.5.0.html
I wonder if any of them are having some effect in the slow connection.
There are some network properties that you can tweak with. Did you try them?

Problem with socket connection in midp 2.0
hello everyone.
I'm new one in j2me and I am learning socket connection in j2me. I'm using basic socket,datagram example wich is come with sun java wireless toolkit 2.5. for it i wrote small socket server program on c# and tested it example on my pc and its working fine. also socket server from another computer via internet working fine. But when i instal this socket example into my phone on nokia n78 (Also on nokia 5800) it's not working didn't connect to socket server.. On phone I'm using wi-fi internet. Can anybody help me with this problem? I hear it's need to modify manifest file and set appreciate pressions like this
MIDlet-Permissions: javax.microedition.io.Connector.socket,javax.microedition.io.Connector.file.write,javax.microedition.io.Connector.ssl,javax.microedition.io.Connector.file.read,javax.microedition.io.Connector.http,javax.microedition.io.Connector.https
is it true?
can anybody suggest me how can i solve this problem?
where can I read full information about socket connection specifiecs in j2me?
Thanks.Maybe this can be helpful:
[http://download-llnw.oracle.com/javame/config/cldc/ref-impl/midp2.0/jsr118/index.html]
you can check there the Datagram interface anda DatagramConnection interface and learn a little about that.
If the client example runs fine in the wireless toolkit emulator, it should run the same way in your phone; i suggest to try to catch some exception that maybe is hapenning and display it on a Alert screen, this in the phone. -
Multiple clients on socket connection
Hi!
I understand that it is possible that multiple clients listen to one server (on the same port) and even write to it (then it should be a multi-threaded server).
But i would like to refuse connectios, if one client is connected. How can I do that?
In my case I have a (single threaded) server. Now one clients connects. The server waits to receive data from the client and answers, without ever closing the port. that works.
Now if I connect with a second client, the openicng of the socket in the second client works fine, although the server does not seem to notice the second client. Communication is not possible between the server and the second client, and the server doesn't answer to the first client anymore, although he receives data from it.
So, since the server does not seem to notice the second client (does not accept the connection) and I don't get an exception at the second client, what can I do?
Thank you for your help!
concerned Code (if you want to take a look at it):
CLIENT:
socket = new Socket(hostname, echo_port);
SERVER:
try
ServerSocket waitingsocket = new ServerSocket(echo_port);
try
socket= waitingsocket.accept();
System.out.println("Client connected");
ReaderThread reader = new ReaderThread( this, socket );
reader.start();
catch (Exception e)
READER:
public void run()
while (true)
try {
int bytesRead = inStream.read(inputBuffer,
0, inputBuffer.length);
readCallback.tcpUpdate(inputBuffer,bytesRead);
catch (Exception oops)
readCallback.tcpUpdate(null,-1);
Just to make sure this is clear: You can NOT have multiple clients on a given socket connection. You CAN have multiple clients connected to a particular port on a given server, but each client will be communicating with the server through a different of socket.
The usual approach here is to set up a listening ServerSocket on the desired port, call accept() on it, then process the communication from the returned Socket object. This is usually done by spawning a new thread and allowing it to handle the socket communication, while the ServerSocket loops around to another accept() for the next communication.
Here's an excellent intro to the concepts (the code is really ugly and poorly implemented, but it does a good job of explaining the overall concept). I used this as a starting point, and now (after a whole lot of development) have a pretty sweet extensible web server class that handles template expansion, etc... (I use this as a quick and dirty UI for some of my apps, instead of requiring the user to install a JSP container):

TCP Socket connection in CLOSE_WAIT status and not getting closed
I am facing an issue with the TCP socket connections not getting closed and they are in CLOSE_WAIT status for ever.
As a part of batch process in our application, emails are sent with 4 embedded images. These images are downloaded from 3rd party site with IP say "UUU.XXX.YYY.ZZZ"
The images are embedded to email as follows
1. An URL object is created with the site url.
URL urlPhoto = new
URL("http://UUU.XXX.YYY.ZZZ/email/photos.jpg");
2. The image cid is created with the URL object and the image name
HtmlEmail htmlEmail = new HtmlEmail();
String cid1 = htmlEmail.embed(urlPhoto,
"photo.jpg");
3. The image cid is added to the email template by replacing the ${cid1} and the email is sent.
<td valign="top">
<img src="cid:${cid1}" width="279" height="274">
</td>
When a mail is sent, 4 new TCP connections are opened and are put in CLOSE_WAIT status for ever. For every mail sent 4 new connections are opened. In UNIX there is an upper limit on the number of open file handles (defaults to 1024) at any point of time. The open TCP connection has the underlying socket in CLOSE_WAIT status and is not getting closed at all. When the upper limit (1024) is reached the batch process is throwing the following exception and terminates.

I tried 2 solutions
1. Got the HttpURLConnection from the URL object and invoked disconnect method on the same. But it doesn�t work.
2. Ran the batch process java program with the parameter �Dhttp.keepAlive=false to close the underlying connection but didn�t help.
I need the underlying sockets to be closed and not put in CLOSE_WAIT status after sending the mail.
Is it the problem with the embed method of HtmlEmail object not closing the underlying socket connection.
If anyone has faced this issue before, kindly let me know the possible solutions for the same ASAP.
Thank you,
Ramesh GThis sounds more like a problem due to connection pooling at middle tier/application server.
If that has been ruled out, then you might to enable DCD or set expiry time on the server. -
Socket connection time Out - Sender File adapter (Intermittent Issue )

In our sender file adapter i am getting the following issue:
I have already places timout : 120 secs.
This isssue is occuring intermittently.
Error occurred while connecting to the FTP server "100.142.131.30:21": java.net.ConnectException: Socket connection timed out: 100.142.131.30:21Hi Renu,
You need to increase the timeout Seconds and check.
Run the report RSFTP002.
and check whether the connection to FTP works. Provide the below parameters:
user = <your ftp user>
pwd = <your ftp pwd>
host= <your ftp host/ip>

I have an issue with a college project I'm working on.
Using Actionscript 3, I made a simple .swf program, an animated, interactive smiley, that 'reacts' to number inputs in a input-box.
For the sake of the project, I now need to make the framework for establishing a socket connection with the smiley .swf, and another program.
This is where I encounter issues. I have very little knowledge of AS3 programming, so I'm not certain how to establish the connection - what's required code-wise for it, that is.
To test the connection, I'm attempting to use the "TCP/IP builder" program from windows, which lets me set up a server socket. I need to program the .swf file into a client - to recognize it, connect to it, then be able to receive data (so that the data can then be used to have the smiley 'react' to it - like how it does now with the input-box, only 'automatically' as it gets the data rather than by manual input).
My attempts at coding it are as follows, using a tutorial (linked HERE):
//SOCKET STUFF GOES HERE
var socket:XMLSocket;
stage.addEventListener(MouseEvent.CLICK, doConnect);
// This one connects to local, port 9001, and applies event listeners
function doConnect(evt:MouseEvent):void
stage.removeEventListener(MouseEvent.CLICK, doConnect);
socket = new XMLSocket("127.0.0.1", 9001);
socket.addEventListener(Event.CONNECT, onConnect);
socket.addEventListener(IOErrorEvent.IO_ERROR, onError);
// This traces the connection (lets us see it happened, or failed)
function onConnect(evt:Event):void
trace("Connected");
socket.removeEventListener(Event.CONNECT, onConnect);
socket.removeEventListener(IOErrorEvent.IO_ERROR, onError);
socket.addEventListener(DataEvent.DATA, onDataReceived);
socket.addEventListener(Event.CLOSE, onSocketClose);
stage.addEventListener(KeyboardEvent.KEY_UP, keyUp);
function onError(evt:IOErrorEvent):void
trace("Connect failed");
socket.removeEventListener(Event.CONNECT, onConnect);
socket.removeEventListener(IOErrorEvent.IO_ERROR, onError);
stage.addEventListener(MouseEvent.CLICK, doConnect);
// Here, the flash tracks what keyboard button is pressed.
// If 'q' is pressed, the connection ends.
function keyUp(evt:KeyboardEvent):void
if (evt.keyCode == 81) // the key code for q is 81
socket.send("exit");
else
socket.send(evt.keyCode);
// This one should handle the data we get from the server.
function onDataReceived(evt:DataEvent):void
try {
trace("From Server:", evt.data );
catch (e:Error) {
trace('error');
function onSocketClose(evt:Event):void
trace("Connection Closed");
stage.removeEventListener(KeyboardEvent.KEY_UP, keyUp);
socket.removeEventListener(Event.CLOSE, onSocketClose);
socket.removeEventListener(DataEvent.DATA, onDataReceived);
Trying to connect to the socket gives me either no result (other than a 'connection failed' message when I click the .swf), or the following error:
Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: file:///C|/Users/Marko/Desktop/Završni/Flash%20documents/Smiley%5FTCP%5FIP%5Fv4.swf cannot load data from 127.0.0.1:9001.
at Smiley_TCP_IP_v4_fla::MainTimeline/doConnect()[Smiley_TCP_IP_v4_fla.MainTimeline::frame1:12]Tried adding that particular integer code, ended up with either errors ("use of unspecified variable" and "implicit coercion") , or no effect whatsoever (despite tracing it).
Noticed as well that the earlier socket code had the following for byte reading:
"sock.bytesAvailable > 0" (reads any positive number)
...rather than your new:
"sock.bytesAvailable != 0" (reads any negative/positive number)
Any difference as far as stability/avoiding bugs goes?
So then, I tried something different: Have the program turn the "msg" string variable, into a "sentnumber" number variable. This seemed to work nicely, tracing a NaN for text (expected), or tracing the number of an actual number.
I also did a few alterations to the input box - it now no longer needs the 'enter' key to do the calculation, it updates the animation after any key release.
With all this considered and the requirements of the project, I now have a few goals I want to achieve for the client, in the following order of priority:
1) Have the "sentnumber" number variable be recognized by the inputbox layer, so that it puts it into the input box. So in effect, it goes: Connect -> Send data that is number (NaN's ignored) -> number put into input box -> key press on client makes animation react. I optionally might need a way to limit the number of digits that the animation reacts to (right now it uses 1-3 digit numbers, so if I get sent a huge number, it might cause issues).
- If the NaN can't be ignored (breaks the math/calculus code or some other crash), I need some way of 'restricting' the data it reads to not include NaN's that might be sent.
- Or for simplicity, should I just detect the traced "NaN" output, reacting by setting the number variable to be "0" in such cases?
2) After achieving 1), I'll need to have the process be automatic - not requiring a keyboard presses from the client, but happening instantly once the data is sent during a working connection.
- Can this be done by copying the huge amounts of math/calculus code from the inputbox layer, into the socket layer, right under where I create the "sentnumber" variable, and modifying it delicately?
3) The connection still has some usability and user issues - since the connection happens only once, on frame 1, it only connects if I already have a listening server when I run the client, and client can't re-connect if the server socket doesn't restart itself.
I believe to do this, I need to make the connection happen on demand, rather than once at the start.
For the project's requirement, I also need to allow client users to define the IP / port it's going to connect to (since the only alternative so far is editing the client in flash pro).
In other words, I need to make a "Connect" button and two textboxes (for IP and port, respectively), which do the following:
- On pressing "Connect", the button sets whatever is in the text boxes as the address of the IP and port the socket will connect to, then connects to that address without issues (or with a error message if it can't due to wrong IP/port).
- The connection needs to work for non-local addresses. Not sure if it can yet.
- On re-pressing connect, the previous socket is closed, then creates a new socket (with new IP/port, if that was altered)
It seems like making the button should be as simple as putting the existing socket code under the function of a button, but it also seems like it's going to cause issues similar to the 'looping frames' error.
4) Optional addition: Have a scrolling textbox like the AIR server has, to track what the connection is doing on-the-fly.
The end result would be a client that allows user to input IP/Port, connects on button press (optionally tracking/display what the socket is doing via scrollbox), automatically alters the smiley based on what numbers are sent whilst the connection lasts, and on subsequent button presses, makes a new connection after closing off the previous one.
Dropbox link to new client version:
https://www.dropbox.com/s/ybaa8zi4i6d7u6a/Smiley_TCP_IP_v7.fla?dl=0
So, starting from 1), can I, and how can I, get the number variable recognized by "inputbox" layer's code? It keeps giving me 'unrecognized variable' errors. -
How to retain socket connection for multiple requests in java 1.3
Hi All,
My problem is to retain client socket connection without opening and closing socket connection for every request.I want to open the socket connection once and send multiple requests one after the other based upon the response over the same socket.Finally I want to close the socket only after completing all my requests and receiving respective responses.I don't want to open and close the socket for each request and response.While at the same time I expect the socket to send each request only after receiving the response for the previous request.
I am using java 1.3 and I am looking for the solution in same version.
Please help me .
Thanx in advance.Look at my response to "Telnet to Unix box from Java"

on "Java Programming" forum. It does exactly that to run the signon and a command. It would be easy to extend it to do multiple commands. -

} catch (error:Error){
trace('NO crossdomain.xml\n'+error.message+'\n');
socket = new Socket();
configureListeners(socket);
try {

socket.connect(host, port);
} catch (error:Error) {
trace(error.message + "\n");
socket.close();
In the third row i load the policy file but i suppose the
loading is fine because flash don't tell me any error when it's
load.
Any suggestion? -
Mobile-Desktop socket connection
I have a client program running on a mobile and a server program running on my desktop, I am trying to establish a socket connection between them and send "hello" message from the mobile to the desktop, here are the codes
Client:

Connector.open("socket://xxx.xxx.xxx.xxx:4444");
myDisplay.setCurrent(form);
OutputStream os = null;
try{
os = sc.openOutputStream();
byte[] data = "Hello/".getBytes();
os.write(data);
os.flush();
} finally{
sc.close();
os.close();
} catch (IOException x){
x.printStackTrace();
}Server:
public void Server()
ServerSocket serverSocket=null;
Socket clientSocket = null;
try {
serverSocket = new ServerSocket(4444);
clientSocket = serverSocket.accept();
} catch (IOException e) {
System.out.println("Could not listen on port: 4444");
System.exit(-1);
System.out.println("Connection Established");
try
char[] input=new char[1000];
int i=0;
char delimiter='/';
InputStream in=clientSocket.getInputStream();
while ((input=(char)in.read()) != delimiter){
System.out.println(input[i]);
i++;
in.close();
clientSocket.close();
serverSocket.close();
}catch(IOException e)
e.printStackTrace();
}I run the server then I run the client, "Connection Established" message appeares indicating that the desktop successfully accepted the connection request from the mobile, however, the "Hello" message doesn't appear afterwards, nothing appeares after the "Connection Established" message actually, So what has gone wrong?You will find that using Sockets with MIDP is going to be hard work for you. (different phones different behavior, and many network providers do all sorts of funny firewalling).
Are you able to use HTTP instead? E.g. XML over http. -
I have a form that sends mail (smtp) through a socket
connection (actionscript), which I picked up here,
http://www.bytearray.org/?p=27
Tested and works fine locally, but when posted online and
tested, it quietly fails.
I am trying to send mail from my domain, to the mail function
within my host server. (same domain).
Tried both "local" and "network" publishing options.
I have read the article on socket security at
http://www.adobe.com/devnet/flashplayer/articles/fplayer9_security_04.html
but I do not have the option to place a crossdomain.xml file
at port 843 since I am on a shared server.
I've read everything that I can online but because policy
changes from player 9,0,115,0 on, it seems that older posts may not
be relevant, so is there another way to approach this matter?
Is it possible for me to hard code the cross domain policy
into my scripts or .fla?
Thanks,
Key.I seem to be having the same problems, I can't make a
connection using the newest player and I have my crossdomain file
on the root of the server, does anyone have any clue how to solve

ManjuHi!
I posted a TAR on metalink for this "read timed out" problem. This is the answer I got:
apparently the messages that you listed seem refer to a problem in reading request data from the client - so the HttpIOException is triggered.
I have made a little research on HttpIOException in request-reading context. There are only
two situations in which HttpIOException can be raised without an causing IOExce
ption, and I think none of them applies. So we'd have some kind of IOException t
hat causes the HttpIOException. It might well be a SocketException, because the
text "Read timed out" is as far as I know the standard text for SocketException
if the socket's SoTimeout has been reached.
In fact there is a configuration parameter for OC4J (though undocumented), which allows you to set the Socket's SoT
imeout -- and the default is 15000 (measured in milliseconds). The name is "orac
le.j2ee.http.socket.timeout", and it should be available in OC4J 9.0.3.1 and hig
her (I am definitely sure that it exists in OC4J 9.0.4.1).
So can you please add something like "-Doracle.j2ee.http.socket.timeout=120000" to the startup comma
nd for your standalone OC4J container to increase the timeout from 15 seconds to
2 minutes?
It helped us, although some requests time out "normally" instead.
