Send a string to a server
Hi,
I am going to write a java application that sends a string so a server. I don�t know what is on the server side(someone else has written the server part) just that my program is going to use sockets and what port number and IP the server has. I first start using datagrampackets but then I have to use byte array that would not work if the server just want a string ?? What should I use?
/Thanks in advance
Hi,
your question is not clear... you can convert the byte array to a string by calling toString method on the byte array.. since the server port and IP is known, try amking a socket and send a string and see what happens by opening a socket inputstream.. read from the stream to understand what the server does..

HTTPService problems while sending a String Variable to Server
I have an xml in string form..... I want to send it as an http request to the server, which is written in .NET... server wud make its decession on the basis of this xml and wud return me another xml as http response..
Problem ---->
this request reaches server but when i look at the request reached at server it has my client infotmation but does not has my variable anywhere...... i iterate through all the parameters in Request.Params... but I don't find my string at all.... any idea why I can't find my sent variable ???
Actionscript code to send xmlString to .NET Server using HTTPService:
public function sendRequest(syncXmlString : String, httpResultHandler : Function) : void {
try {
var objectParam : Object = {name:PARAM_NAME, value:syncXmlString };
var params : Object = [objectParam];
var httpService : HTTPService = new HTTPService();
httpService.url = serverUrl;
httpService.method = HTTPRequestMessage.POST_METHOD;
httpService.contentType = HTTPService.CONTENT_TYPE_XML;
httpService.resultFormat = HTTPService.RESULT_FORMAT_XML;
httpService.addEventListener(ResultEvent.RESULT, httpResultHandler);
httpService.addEventListener(FaultEvent.FAULT, httpFaultHandler);
httpService.send(params);
} catch (err : Error) {
Alert.show(err.message);
Thanks and Regards,
Ahmed.No, that is the problem, the request object should not be an indexed array[], it should be an Object{}. Remove that imtermediate array and pass objectParams in the send()
Also, don't mess with the contentType without very good reason.
httpService.contentType = HTTPService.CONTENT_TYPE_XML;
that says you are sending XML, but you are not, you are sending the default name=value pairs. Remove that assignment and leave it at the default "form"
One more, you do not want that resultFormat, it is the legacy AS2 class. You want E4X
httpService.resultFormat = RESULT_FORMAT_E4X;

Remove the while loop and just write your ouput and close the connection on the server. -
Sending more than one string from a server to a client in TCP/IP
hi,
i have two VIs where one is the server and the other the client in TCP/IP. I need to send more than 2 strings to the client at the same time.i have used the XML method but then by using XML i cant send any thing else to the client because of the byte sizes. so either i need a new way to send the strings or a new way to send more data. i have attached my VIs to this post if you need to take a look.
thanks,
Rambaldi.

ServerClient.zip 83 KBWell, after looking at the code it is very difficult to understand what you are trying to do. Not to be nasty or anything but your code is a mess. Did you know that in both VIs you have an infinite loop? The only way to exit your VIs is to use the Abort button. This is bad since it doesn't allow you to actually perform any type of cleanup. Your wiring is very difficult to follow. You should also avoid using local variables to pass data through your application. If you need to pass data between two parallel processes use queues, notifiers or an action engine. You can get rid of all of the sequence frames that you have. They aren't really doing anything for you and are unnecessary.
As to your particular question I would have to assume that it is simply a result of bad coding that is preventing you from sending more than one string. You have logic in the second loop that appears to be impossible to get to since the conrol used to switch the case statement is placed on a hidden part of the front panel. Take a look at the TCP server example I posted in this thread. The example is on the second page of that thread.
In order to help you I think you need to provide a good description of exactly what you want your server and client to do. You also need to do some code cleanup to make it readable and easier to follow.

Once I send 1 string, the rest are cut off, any ideas?
Hello everyone.
For some reason when I send my first string through the socket, everything works fine. But after that Its cutting off the first 2 or 3 characters of the string and I have no idea why because I'm flushing the output buffer before and after I send the the string to the output buffer.
note: complete code can be found here:
http://cpp.sourceforge.net/?show=38132
Am I not flushing right?
Here's the code:
public class MultiThreadServer implements Runnable {
//csocket is whatever client is connecting to this server, in this case it will
//be a telnet client sending strings to the server.
Socket csocket;
MultiThreadServer(Socket csocket) {
this.csocket = csocket;
public void run() {
//setting up sockets
Socket outputServ = null;
//create a message database to store events
MessageDB testDB = new MessageDB();
try {
//setting up channel to recieve events from the omnibus server
BufferedReader in= new BufferedReader(
new InputStreamReader(
csocket.getInputStream()));
PrintWriter out2
= new PrintWriter(
new OutputStreamWriter(
csocket.getOutputStream()));
//This socket will be used to communicate with the z/OS reciever
//we will need a new socket each time because this is a multi-threaded
//server thus, the z/OS reciever (outputServ) will need to be
//multi threaded to handle all the output.
outputServ = new Socket("localhost",1234);
if(outputServ.getLocalSocketAddress() == null)
System.out.println("OutputServer isn't running...");
//Setting up channel to send data to outputserv
PrintWriter out
= new PrintWriter(
new OutputStreamWriter(
outputServ.getOutputStream()));
String input;
//accepting events from omnibus server and storing them
//in a string for later processing.
while ((input = in.readLine()) != null)
//looking to see what telnet gets
out2.println(input);
out2.flush();
//accepting and printing out events from omnibus server
//also printing out connected client information
System.out.flush();
System.out.println("Event from: " + csocket.getInetAddress().getHostName()
+"-> "+ input +"\n");
System.out.flush();
//sending events to output server
out.flush();
out.println(input);
out.flush();
//close the connection if the client drops
if(in.read() == -1)
System.out.println("Connection closed by client.");
break;
//cleaning up
in.close();
out.close();
outputServ.close();
csocket.close();
catch (SocketException e )
System.err.println ("Socket error: " + e);
catch(UnknownHostException e)
System.out.println("Unknown host: " + e);
catch (IOException e)
System.out.println("IOException: " + e);
}Here's some example output I'm getting from the telnet screen which is (out2) stream:
This is a test
This is another test
his is another test
This is yet another test
his is yet another test
This is a test worked fine, as you can see, it outputed This is a test when I typed it in.
The next string "This is another test" fails, as you can see its echoing out:
his is another test
I'm also printing out the contents to the console, and i'm getting out the same thing:
Enter port to run server on:
3333
Listening on : ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=3333]

Event from: localhost-> his is another test
Event from: localhost-> his is yet another test

I'm new to consuming web services in JDeveloper. I'm using Oracle JDEV 10.1.3.3/OC4J. I'm using this version since it is compatible with Oracle EBS 12.1.3. My intent is to pull data from our third party recruitment app (Success Factors) and load that data into Oracle HRIS. I'm already doing this through a .NET application. I'm converting it to be a Java Concurrent Program in EBS. The code listed below is a stub call to verify I'm on the right track. I created a JDeveloper Web Services proxy project. I'm testing it locally on my windows desktop. When I'm able to consume the service successfully, then I'll think about moving it to the EBS server.
I'm getting the following error when I invoke the following service:
HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: String index out of range: -7
End point is: https://api4.successfactors.com/sfapi/v1/soap?wsdl

That might be because you are sending incorrect data and the other end fails to validate it.
You might be able to guess based on your C# code. But, since you are using soap one generic solution is available to you.
- Get an http proxy interceptor like wireshark.
- Run it while your C# app runs, collect the http requests from that.
- Run it while running your java code, collect the http requests from that.
Compare the two. -
When to send JOIN channel to IRC server?urgent..
i have a problem regarding sending information to IRC server. I want to send the join message to server. But i can only do so after server has finished sending information to me. may i know the correct coding ? i have tried to send it after the while loop but within the try {} it still wouldnt send. when i tried to send it earlier by placing the code above the while loop, the server will display error requesting me to register first.

}i had a similiar problem, i believe the solution was to wait after sending the "NICK" or "USER" commands to receive some sort of response (could be PING) look at the RFC (www.rfc-editor.org) and if you don't find it there i can post the code i used but its long and messy.
but i think your problem is you need to respond to a ping (or some other command) after trying to authorize. -
RE: Sending jpg bytes over a server
I had another topic but it has not been answered for a couple days so I guess I will clarify my problem more.
I'm sending my image over a server, Client->Server->Client.
My sending and receiving works but I get the image and it cannot be displayed.
Sending
try{
FileInputStream fis = new FileInputStream("picture.jpg");
byte[] buffer = new byte[fis.available()];
fis.read(buffer);
return buffer;
}catch(Exception e){
System.out.println("Loading Image error");
}Receiving
try{
FileOutputStream fos = new FileOutputStream("received.jpg");
fos.write(image);
ImageIcon display = new ImageIcon("received.jpg");
clientDisplayPicture=new JLabel(display);
}catch(Exception h){
System.out.println("Problem receiving");
}Am I packaging it wrong? The received image is 0bytes. Thanks in advance!Here you are ignoring the result of the read() method.Meaning?
Here you are not telling us how the incoming data got into 'image'.I put the bytes of the image into an object and passed it over the network.
public void displayPicture(String from, byte[] image, boolean a, boolean b){
try{
FileOutputStream fos = new FileOutputStream("received.jpg");
fos.write(image);
fos.close();
}catch(Exception h){
System.out.println("Problem receiving");
public byte[] getImage(){
try{
FileInputStream fis = new FileInputStream("picture.jpg");
File f = new File("picture.jpg");
int bsize = 1375;
byte[] buffer = new byte[bsize];
fis.read(buffer);
fis.close();
return buffer;
}catch(Exception e){
System.out.println("Loading Image error");
return null;
}EDIT: Thanks, got it working, the above worked. THANKS!

Send multiple strings over TCP - Like messenger service
Hello all Java Coders,
I'm new with TCP programming.
I'm beggining to learn about TCP and sockets connections in Java. In order to achieve this, I was coding a mini-program so I can learn a little bit about this.
I'm trying to make a simple TCP program.
The server sends a string to a client...
I already searched for a couple of hours in google and so on, about what I'm doing wrong.
[The server code (Just click)|http://pastebin.com/m39fd1273]
[The client code (Just click)|http://pastebin.com/m57471803]
I hope that someone can help me with this and, if you have patience, please tell me the reasons my code doesn't work.
Many thanks,
Freiheitpt
P.S.: I think that the problem is on the server side...Sorry jverd.
I was just trying to put things organized.
Well, I can't get the String to be sent to the client.
No error occurs.
Server:
try {
srvr = new ServerSocket(1234);
System.out.println("Connecting...");
skt = srvr.accept();
System.out.println("Connected!\nPreparing data exchange...");
stream = skt.getOutputStream();
out = new PrintWriter(stream, true);
System.out.println("Done!\nReady to Send!");
} catch (IOException ex) {
System.out.println("Ups, didn't work!");
System.exit(1);
while(!data.equalsIgnoreCase("end")) {
System.out.print("String to send: ");
data = input.nextLine();
System.out.print("Sending string: '" + data + "'\n");
out.print(data);
}Client:
try {
skt = new Socket("localhost", 1234);
System.out.println("Connecting...");
if (skt.isConnected()) {
System.out.println("Connected!\nPreparing data exchange...");
stream = skt.getInputStream();
inputStream = new InputStreamReader(stream);
in = new BufferedReader(inputStream);
System.out.println("Done!\nReady to Receive!");
} else {
System.out.println("Server not available!\nExiting...");
skt.close();
System.exit(1);
} catch (IOException ex) {
System.out.println("Ups, didn't work!");
System.exit(1);
while (!data.equalsIgnoreCase("end")) {
while(!in.ready()) {}
data = in.readLine();
System.out.println("Received String: '" + data + "'");

Advisor connector failed to send analysis data to management server
We are using the online advisory server on the servers we can, we continue to get the following on multiple servers - "Advisor connector failed to send analysis data to management server"

Does anyone have any information that would lead us to resolve this?
