Creating a TSL/SSL socket connection to a server

Hi
Is it posible to create a TSL/SSL socket connection to a server with as3 - webapp, I foundSecureSocket but it seems like it is only for Air, and is not in the flex 4.5 sdk?
Then NetConnection has it, but can you use it with a server that we have created our self? I think I read that if we use flashremoting, we can?
We are using As3Crypto but there is a lot of overhead on using this, as it is not native code.

How to Create a Single Backend Socket connectivity in a Server Socket Pgm

Hi Everybody,
I have a written a Server Socket which connects to back end socket and receiving the data and sending back to the front end. But as per my client requirement i need to create only one socket at the back end. But the code I have written is creating new sockets for each request. Is there any way to use the single client socket connection for all the transactions. I have attached the sample code for the reference.
import java.io.*;
import java.net.*;
import java.nio.ByteBuffer;
import java.nio.channels.SocketChannel;
public class serl implements Runnable
ServerSocket serversocket;
Socket clientsoc;
Socket fromclient;
PrintStream streamtoclient;
BufferedReader streamfromclient;
SocketChannel socket_channel=null;
Thread thread;
public serl()
try
serversocket = new ServerSocket(1001);//create socket
clientsoc = new Socket("10.100.53.145",200);
socket_channel = clientsoc.getChannel();
catch(Exception e)
System.out.println("Socket could not be created "+e);
thread=new Thread(this);
thread.start();
public void run()
try
while(true)
PrintStream streamtobackend=null;
BufferedReader streamfrombackend = null;
fromclient=serversocket.accept();//accept connection fromclient
streamfromclient=new BufferedReader(new InputStreamReader((fromclient.getInputStream())));
//create a input stream for the socket
streamtoclient=new PrintStream(fromclient.getOutputStream());
//create an a output stream for the socket
String str=streamfromclient.readLine();
//read the message sent by client
System.out.println("Output Input From Vtcpd "+str);
streamtobackend.print(str);
streamtobackend = new PrintStream(clientsoc.getOutputStream());
//create an a output stream for the backend socket
streamfrombackend = new BufferedReader(new InputStreamReader(clientsoc.getInputStream()));
//create a input stream for the backend socket
str=streamfrombackend.readLine();
System.out.println("Output From Backend Client"+str);
streamtoclient.println(str);
}//end of while
catch(Exception e)
System.out.println("Exception "+e);
finally
try
fromclient.close();
catch(Exception e)
System.out.println("could not close connection "+e);
public static void main(String ar[])
new serl();
}

Srikandh,
Create a singelton pattern for you socket ( IP, port, etc..) and each time you read the input stream and write to the output stream, do the following to the socket to reset it in the working thread
fromclient.getInputStream().mark(0);
fromclient.getInputStream().reset();Hope this could help

This error usually occurs because you have not authorized the client's IP address in UCM. The steps to add the WebCenter host to the list of authorized clients are detailed in section [4.3.1.3.1 of the Installation Guide|http://download.oracle.com/docs/cd/E12839_01/install.1111/e12001/webcenterservice_install.htm#sthref161].

SSL Sockets.

Hey guys, I've been searching my brains and these forums for ages trying to get my app to work, and now that it does work...I have no idea why.
Here's a rundown of the situation.
I have a server, TLS enabled. I have a client, TLS enabled. I have an application, that will create an instance of the client to connect to the server.
This is what I wanted to happen.
1) Server running
2) Application, upon start, creates a client instance and connects to the server
3) I wanted to server to start a handshake and wanted both the server to ouput "finished handshake" to system.out once the handshake was completed. (Same with client side, wanted it to say finished too).
4) App sends login msg to server (via client.send(msg) method.
5) Server reads msg and prints it to screen.
For some reason, my app/client connected to the server fine; the server spat out this:
Finalizer, called close()
Finalizer, called closeInternal(true)
Finalizer, SEND TLSv1 ALERT: warning, description = close_notify
Finalizer, WRITE: TLSv1 Alert, length = 2
But then no handshake! the handshake only occurred after I sent some data to the server. AND!! the server wasn't printing anything to screen. It was definitely getting something as it spat this out:
Thread-0, READ: TLSv1 Application Data, length = 32
But the string I sent it wasn't printed to screen (usually comes underneath it).
Anyway, a day later, I think, hold on a minute...I haven't setUseClientMode(boolean) on either the client or server. So I add this to the code(s) and walla....now I get:
Thread-0, READ: TLSv1 Application Data, length = 32
String sent to server
However, the server still doesn't initiate the handshake until I sent this string. Not that it matters, but why????? Code is below!
public class Server{
    private ServerSocket getServerSocket() throws Exception{}
    private void run(){
        try {
            System.out.println("Listening on port " + serverPort);
            ServerSocket sslServerSocket = getServerSocket();
            do {
                SSLSocket client = (SSLSocket)sslServerSocket.accept();
                (new ServerSocketThread(client)).start();
            while (true);
        catch (Exception exception)
            System.out.println("Error listening on port " + serverPort);
            exception.printStackTrace();
    class ServerSocketThread extends Thread {
        SSLSocket socket;
        public ServerSocketThread(SSLSocket s){
            this.socket = s;
        public void run(){
            try {
                socket.setUseClientMode(false);
                /*socket.startHandshake();
                socket.addHandshakeCompletedListener( new HandshakeCompletedListener() {
                    public void handshakeCompleted(HandshakeCompletedEvent event) {
                        System.out.println("Handshake finished!");
                        System.out.println("\t CipherSuite:" + event.getCipherSuite());
                        System.out.println("\t SessionId " + event.getSession());
                        System.out.println("\t PeerHost " + event.getSession().getPeerHost());
                // read from client
                InputStream inputstream = socket.getInputStream();
                InputStreamReader inputstreamreader = new InputStreamReader(inputstream);
                BufferedReader bufferedreader = new BufferedReader(inputstreamreader);
                // write to client
                OutputStream outputstream = socket.getOutputStream();
                OutputStreamWriter outputstreamwriter = new OutputStreamWriter(outputstream);
                BufferedWriter bufferedwriter = new BufferedWriter(outputstreamwriter);
                String string = null;
                String command = "";
                while ((string = bufferedreader.readLine()) != null){
                    System.out.println(string);
                    System.out.flush();
            catch (Exception e){
                System.out.println("Error writing / reading");
                e.printStackTrace();
    }The commented out code is the handshake. I got rid of it since it wasn't doing what I thought it would.
public class client{
   protected void connect(){
            SSLSocketFactory sslsocketfactory = sslc.getSocketFactory();
            clientSocket = (SSLSocket)sslsocketfactory.createSocket(HOSTNAME, PORT);
            clientSocket.setUseClientMode(true);
    protected void send(String msg){
        String reply = "";
        String cmd = "";
        try {
            bufferedwriter.write(msg + '\n');
            bufferedwriter.flush();
        catch (Exception e){
            e.printStackTrace();
Obviously there are some parts of the code missing. I did that so there wouldn't be too much to read. Tried to put the important stuff here. If you need more, let me know.
Thanks.
Regards,
DJVege...

This should work assuming you are creating the SSLServerSocket correctly. You don't need the setUseClientMode settings as the ones you have are the default for SSLSockets created by connecting or accepting respectively. You are aware that the handshake doesn't happen by default until you do some I/O, but you can provoke it with startHandshake() at the client. The server doesn't initiate the handshake, the client does.

Sockets connection

Can anybody help me how to connect Flash to a server Using Sockets connection using in AS3.

Use following code UPDATED:
try
var mySocket:Socket = new Socket();
var isConnected:Boolean = false;
var portNumber:Number =8000; //Enter Port number you want to use instead of 8000;
var IPAddress:String = "localhost"; //Enter server IP instead of localhost;
//Valid range of port numbers is 1 to 65535
if (portNumber >= 1 && portNumber <= 65535)
//Create new socket.
mySocket=new Socket ;
//Connect to host and port.
mySocket.connect(IPAddress,portNumber);
//Add listeners to socket to start communicating with the server.
mySocket.addEventListener(IOErrorEvent.IO_ERROR,errorOccured);
mySocket.addEventListener(SecurityErrorEvent.SECURITY_ERROR,errorOccured);
mySocket.addEventListener(ProgressEvent.SOCKET_DATA,readFromServer);
mySocket.addEventListener(Event.CONNECT,connectionEstablished);
else

function writeToServer(toUserName:String, messageStr:String):void
if (isConnected)
var pushStr = "Message from Flash to server";
mySocket.writeUTFBytes(pushStr);
mySocket.flush();
//This function is called when connection to server is successful.
function connectionEstablished(evnt:Event)
//Mark socket connection with the server as connected.
isConnected = true;
function errorOccured(evnt:Event)
//Some error occured
trace("Some error occured!");
ExternalInterface.call("alert","Some error occured!");

Having problems with shut-down of server after I open a socket connection (which fails to connect)

Basically here is an example servlet - new iPlanet 4.1sp9 instance with an empty classpath (apart from the servlet class) - running solaris v5.6 (Generic_111446-02)
If you run the servlet and then try to shut-down iPlanet it hangs. If you remove the 'new Socket(...' line then it's fine. Any ideas why a failed socket connection stops the server restarting? (Connecting to a listening port does not exhibit this behavior).

Rob:
it's due to JVM signal handler that catches the stop signal and you're forced to use a kill -9 -
Note that the stop script of a fresh install of iWS 4.1SP9 should contain the kill -9 - as a workaround for this known JVM issue.

How to create a Crystal Report to connect to Oracle

Hi,
When I create a Crystal report to connect to SQL Server, I create a stored procedure to get all data I need and connect to it from Crystal Report.(In the stored procedure, I created temp tables, used cusor etc to run data.) But now I need to use a Oracle database. I heard I need to create a package and put this stored procedure in this package. Questions:
1. if I need to create a package, how can I call the stored procedure from it?
2. Can I create temp table in this procedure too? I need to create some temp tables to join together to get complex data.
3. if I want the return data from stored procedure, do I still "select ... from ..." or there is another other ways?
I am so desperated. Please help. I know this are very silly questions. But please.

Hi Jenny,
We are also using Crystal Reports for our Oracle Database, we normally just select the tables we want to use or create our own SQL query.
However, if you really want to use Oracle stored-procedure (which performs faster than a SQL query because the stored procedure is compiled in advance), you can look at this document:
http://support.businessobjects.com/communityCS/TechnicalPapers/scr_oracle_stored_procedures.pdf
Hope this will answer your questions.

Keep opened socket connection?

Hi,
My Java application communicates with server on average every 3 seconds. I wonder if it is a good idea to keep an opened socket connection to the server and don't open new connection for each request. The problem with this is that if in the meantime is connection aborted, java.net.SocketException is throwned.
What do you think about keeping opened connection? Is appropriate to work with opened connections or to open new connection for each new request? How do you solve in your applications situation when communication is irregular but frequent.
Thanks.

I had one more question on this topic relating to capture and processing exceptions. Communication between client and server I accomplish wit these three classes:
- ClientRequest - represents client request to the server
- Communication - gets ClientRequest and socket connection to the server and sends the request to the server
- ServerResponse - represents response returned from the server
Now If Communication class gets dead connection it can't work and throws an exception. We discussed that I should find out the situation and suitably respond to this situation.
My question is whether the method for reconnection should call:
a) Communication class
b) class that uses the Communication class?
c) somebody else (?)
In case a) there is an advantage that all is in one place and Communication class user does not have to worry about anything beause class will try reconnect itself (if second attempt fails, method throws another exception). The advantage of b) is that the user needs, he can respond to this situation and do some another action.
Thanks.

any help would be greatley appreciated.

this is why i am not heart-broken that i will be going the other (executable jar) route.......the major deciding factor is the people who will be using this chat will most likley not be able to edit the policy file due to lack of knowledge, and probably won't want to take the time to try.....they would rather download a program, and double-click execute........
i thank you for taking the time to help me......i have been reading through the posts in this forum, and am seeing it is a good place to get help, so i will be sticking around.....
mahalo and happy java

Studio Creator, Socket Connection to External Device

I am porting an existing & successful project from Netbeans 3.6 into Studio Creator to take advantage of some of the tools in the IDE for this application. The project requires opening a socket connection from the Server PC to an external Device (PLC) that is a Client on a static IP & a dedicated fixed port.
I am struggling to get past some security settings specific to AccessControlExceptions. Here is the code method being used to test:
public String button1_action() {
// Call methods to open connection, init streams, send command, and close connection.
try {
// Open Socket up and accept client connection
ipSocketObject = new ServerSocket(port);
bfSocket = ipSocketObject.accept();
// Establish Streams
is = new BufferedReader(new InputStreamReader(bfSocket.getInputStream()));
os = new PrintWriter(bfSocket.getOutputStream(), true);
System.out.println("Got to here...");
// Clear the msCounter #13002
os.println("r13002=0");
pattern = "13002";
do{ret=is.readLine();} while ((ret.indexOf(pattern)) ==-1);
is.close();
os.close();
bfSocket.close();
ipSocketObject.close();
} catch (IOException e) {
e.printStackTrace();
return null;
The Socket Connection is established, but the command string is not processed before Studio Creator generates a AccessControlException Fault. I have experiemented putting in a SocketPermission statement with out success.
Is anyone aware of some sample code I might be able to review for opening socket connections to clients in a Studio Creator Application? Please excuse this request if too rudimentary- I am an Industrial Controls guy by trade... :)

Sorry I know of no such application at this time, and unfortunately have not done socket work myself for many moons....
What JDK was your previous application written under? I googled for AccessControlException and socket and seems that sometimes accounts for some issues... you can also search for that combination in the forum advanced search and might find something there.... one more long shot suggestion based upon your statement "the command string is not processed".... could it be that you need to flush the stream...?
Sorry I don't have more to offer...

10 minutes. It does not happen every time. We are using JNDI for getting the Datasource objectand using SQL JDBC 3.0 driver. We get following error in log
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Error: "Connection reset by peer: socket write error".)

Urgent help will be appreciated.

So, you've got a network error.. Check your physical layer.

How can i create a socket connection through an http proxy

i'm trying to make a socket connection send an email - i have code that works when you don't have to go through a proxy server but i can't make it pass the proxy server.
import java.net.*;
import java.io.*;
import java.util.*;
public class Mail
public String to_address = "[email protected]";
public String from_address = "[email protected]";
public String sendSub = "HeHeHe";
public String sendBody = "hehehe - it worked";
// This is created to allow data to be read in by the keyboard.
BufferedReader in = new BufferedReader(
new InputStreamReader(System.in));
     private void Mail(String to_address, // recipient's addresses
String from_address, // sender's address
String sendSub, // subject
String sendBody) // Message
               throws IOException, ProtocolException,      UnknownHostException {
     Socket socket;                // creates a Socket named socket
     PrintStream out;               // stream to write to socket
     String host = "imap.btopenworld.com";          // identification of the mail server host
// creates a new socket for connection to the mail server
// as well as two variables for the read and write streams
     socket = new Socket(host, 25); // opens socket to host on port 25 (SMTP port)
     out = new PrintStream(socket.getOutputStream());
// read the initial message
     in.readLine();
// Dialog with the mail server
// send HELO to SMTP server HELO command is given by a connecting SMTP host
     out.println( "HELO " + host );
     out.flush() ;
     in.readLine();
// Once we are connected to the mail server we start sending the email...
// send "from"
     out.println( "MAIL FROM: " + from_address );
     out.flush() ;
     in.readLine();
// send "to"
     out.println( "RCPT TO: " + to_address );
     out.flush() ;
     in.readLine();
// prepare the mailserver to receive the data
     out.println( "DATA" );
     out.flush() ;
     in.readLine();
// Send actual email
     out.println("From: " + from_address);
     out.println("To: " + to_address);
     out.println( "Subject: " + sendSub + "\n" );
     out.flush() ;
     out.println("");
     out.println( sendBody ) ;
     out.println(".") ; // standard to determine end-of-body
     out.flush() ;
     in.readLine();
//Quit and closes socket
     out.println("QUIT");
     out.flush();
     in.close() ;
     socket.close() ;
     return ;
public static void main (String [] args) throws IOException
Mail themail = new Mail();
}

i've tried that but it doesn't seem to do nething - this is how i implemented it...
import java.net.*;

String from_address, // sender's address
String sendSub, // subject
String sendBody) // Message
               throws IOException, ProtocolException,      UnknownHostException {
     Socket socket;                // creates a Socket named socket

     String host = "imap.btopenworld.com";          // identification of the mail server host
// creates a new socket for connection to the mail server
// as well as two variables for the read and write streams
     socket = new Socket(host, 25); // opens socket to host on port 25 (SMTP port)
     out = new PrintStream(socket.getOutputStream());
// read the initial message
     in.readLine();
System.getProperties().put( "proxySet", "true" );
          System.getProperties().put( "proxyHost", "144.124.16.28" );
          System.getProperties().put( "proxyPort", "8080" );
// Dialog with the mail server
// send HELO to SMTP server HELO command is given by a connecting SMTP host
     out.println( "HELO " + host );
     out.flush() ;
     in.readLine();

Problem: Socket connection is not creating in machine, through utility program (MFC Dll), on ListDisplay service port - 3334 (on separate machine), while we are able to telnet on same ListDisplay service port - 3334 from same issue machine on same time

Problem: Socket
connection is not creating in machine, through utility program (MFC Dll), on ListDisplay service port - 3334 (on separate machine), while we are able to telnet on same ListDisplay service port - 3334 from same issue machine on same time
Environment: -
OS:
Windows XP SP2/7
Code:
VC 6.0
Dll: MFC
Problem Description: -
We have written a utility program which create socket (Using windows standard method [MFC]), and then make connection with another service (List Display) running
on port 3334 in different machine and retrieve the required list data. This program was working fine in almost all the machines.
But, we have received a severe intermittent issue on two machines. Client is facing issue in displaying the list data from port 3334.
Attempt: -
First we tried to debug code, and we come to know that socket is not creating in utility program. So we tried to telnet on ListDisplay service port 3334 and we were surprised that we were able to telnet, then we opened some more
telnet window on same port 3334 around (6 to 8) window, and each cmd connected properly. But we were not able to create socket from utility program.
Problem is severe because issue is intermittent.
We have tried all the way, but we are not able to figure it out, that what can be the exact problem and what are the conditions, when utility program will not
connect with ListDisplay service on port 3334.
Kindly assist to resolve this issue. For any help, we would be really thankful.

Hi,
According to your description, it seems that you have created an utility program which is making connection with another service port 3334, however, two clients are facing issue in display the data list from port 3334.
Port: 3334/TCP
3334/TCP - Known port assignments (1 record found)
Service
Details
Source
directv-web
Direct TV Webcasting
IANA
Since the port 3334 is used by directv-web service, I'd like to suggest check this service it is working well on the problematic clients.
1. The client can be resolved in DNS well? Please run "nslookup" in the prompt command.
2. Is there any 3rd party application interrupting? Do test in clean boot.
2. Strongly suggest you run process monitor tool to analysis it.
I am looking forward to your reply if you have any updated on your side.
