Working with sockets with applets

Hello, I am working in my account on a web server, and I am trying to develop a chat using applets. My program works great on the command line, but the applets cannot create a socket because of a SocketPermission problem. I have read about this problem a lot, and I found that applets will only create a socket with the server the applet originates from. I have still not had any success in allowing my applet to create a socket to connect to a server.
I would appreciate any advice concerning this problem!
Thanks so much!
Christina

If you are calling the HTML page containing the Applet as http://localhost then the Applet has to open a socket back to local host.
Make sure you call the applet using the full ip address of the where the web server is running. This should match the socket ip address you are trying to open inside the Applet.

Using sockets with Applet

Hey,
I have a website which has an applet on one of the pages. I put in code that uses a socket to connect to MY computer. ( i want to use my computer as a server which stores data/accounts/etc) A SecurityException was thrown when I tested the applet. Is what I'm trying to do possible? or does something like this have to connect to a server which is on my website?
Thanks

I believe you can run something like this by signing the applet.
And then the user has the option of allowing or disallowing a signed applet to do that kind of thing. I don't know which is the default.

Hi,
I the exact same problem. I didn't quite understand what you meant by closing the socket. When i close the socket on the server side before I enter the whole look it throws an exception. Could please help out and maybe paste a little code to explain further.
Thank you

Issue with file download from BLOB type data

i have been using this for a while, with no problems, including on hosted machines.
the upload to the database works fine.. not the issue, and the download script also works fine, on the local WAMP machine.
but once moved to the server it fails.. the query does not work.
i have a feeling that it is something to do with the managed hosting i am using, but they say no, i have tried it on 2 seperate hosted machines (different providers), with no joy.
if i run the select query on the hoisting server via phpmyadmin, the query runs ok.
any suggestions as to what may be causing the problem on the server compared to the local WAMP machine?
i really don't know where to start looking, or where to point the hosting company.
This is the php code to download the blob data, works fine on local WAMP setup, browser asks if you want to save the file/open etc. as expected.
<?php require_once('Connections/connTracker.php'); ?>
<?php
// if id is set then get the file with the id from database
if(isset($_GET['docindex']))
           {$id    = $_GET['docindex'];
        $query = "SELECT document_name, document_type, document_size, document_content " .
           "FROM tracker_documents WHERE document_index = ".$id;
*** seems to be failing here when running the query ***
$result = mysql_query($query) or die('Error, query failed');
           list($name, $type, $size, $content) = mysql_fetch_array($result);
     header("Cache-Control: maxage=1"); //In seconds
   header("Pragma: public");
     header("Content-length: $size");
           header("Content-type: $type");
           header("Content-Disposition: attachment; filename=$name");
           echo html_entity_decode ($content);}

Hi Gun,
You are the only one responded to my issue. I have allocated some points.
Yes. I have checked the assignment in CRM organizational model.
I did download the org. structure from ECC 5.0
All objects including sales offices are activated for determination and I have verified with green light
As per your suggestion if the sales area data is not matched between the two systems, then how come the error will not reappear during the bdoc reprocess?
What is missing during the first time bdoc process? Looks something is missing for validation module?
Any inputs?
Thanks,
Raj

How can I use a variable in BEx of type date ?

Hello,
I have an infoprovider with a key figure of type "date" and I want to display for example all the data where the date is lower than a date entered by the user.
So I want to create for that a date variable and use it in conditions.
When I try with "manual entry", I can't get the type "date" : it proposes quantity, amount, number but not date.
When I try with "customer exit", I can get the type "date" but when I get it on the selection screen, the date is seen as a number so it doesn't work.
Does anybody have an idea.
Thanks for your help.
Regards,
Vanessa Roulier

Hi!
if you are using a cube then there will be at least one time char. I think you can just add 0calday to your cube , even if you are not filling it.
Once this is available in cube it can be used in query (free chars) where we can define a variable on this 0calday. But we it will not have any effect on query results as you are not storing anything in your query.
then in your conditions you create a variable with USEREXIT type. then in your ABAP code you can access the value stored in variable(which is entered by user) and copy it to the USEREXIT variable. Then your condition works because it is having a date type and the value is date.
I don't see any problem in implementing this scenario.

Unix/win problem with sockets

Hi!
i have a socket with which i send informations to a tcp/ip client. this works very nice, but on unix, the server sends incorrect data ( makes curious tabs ).
how can i fix it so sending text with:
sender = new PrintWriter(sockstream.getOutputStream(), true);
sender.println("test");
will works on unix too.
Thanks
Chris

thanks, how can i set this encoding?
here are two screenshots of this:

How to set FTP Connection type BINARY with the SOCKET

hi all,

PLEASE:: FTP Connection type BINARY with the SOCKET

hi all,
using SOCKET s in the FTP how can i set the Binary mode transfer.
i tried the "TYPE" command with the frist argument as "I"....but :(
Please help me.
Regards,
manish

Socket clientSocket = serverSocket.accept();
Is used when you want to receive data.
... after seding the command it Hangs
Suggenst you want to send data.
The fact that Socket clientSocket = serverSocket.accept(); is because what this
command does is wait untill some client sends you a connection request and when
that happens accept that connection and create a socket for it.
When you want to send data you don't need a ServerSocket.
Socket s = new Socket();
http://javaalmanac.com/cgi-bin/search/find.pl?l=split&words=socket
I could not find any samples using ftp, I guess the URL object would wrap your
messages according to the protocol you want to use and is a better candidate for ftp
than the socket

Panic with Raw Socket-Page fault in module "ip" due to a NULL pointer deref

I see a panic when using raw sockets with Solaris 10 10/09 (u8). I included a sample program that can cause this issue (panic happens when a udp datagram is received on port 60000). This sample code works as expected with the previous version I was using - 5/08. If I bind with a port number of 0 I don't see the panic but I don't receive anything either.
I believe I have all the latest patches installed. I'd appreciate any assistance in resolving this. Thanks...

Wierdness with NIO socket on Solaris 2.10 part I

i tried the following NioClient and MockServer, and saw some weird behavior.
1. If i run both the client and server on the same machine on Windows, the client connects to the server, queries the instrument and gets the list of instruments back.
2. if i run both client and server on the same Solaris 2.10 box, the NioClient doesn't get anything back from the MockServer, not even an ACCEPT
3. if i run the client and the server on different solaris 2.10 machines, they work fine.
have anyone seen this before? can sometone sheds some lights?

Applet Socketing

Im trying to make an applet that will connect to a server program.
I know that the port im using is being forward because i compiled the QuoteServer from the examples and it worked. When I try in an applet it doesnt want to compile.
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
import java.net.*;
import java.util.*;
public class QuoteApplet extends Applet {
DatagramSocket socket;
DatagramPacket packet;
InetAddress address;
byte[] buf;
String received;
public void init() {
    socket = new DatagramSocket();
    address = getCodeBase().getHost();
    System.out.println(address);
public void sendy() {
    // send request
    buf = new byte[256];
    packet = new DatagramPacket(buf, buf.length, address, 4445);
    socket.send(packet);
    packet = new DatagramPacket(buf, buf.length);
    socket.receive(packet);
    received = new String(packet.getData());
    System.out.println("Quote of the Moment: " + received);
    socket.close();
}Its an adaption of the QuoteClient I know if compiled it will do nothing im trying to make sure that the basic structure works.
javac -target 1.5 QuoteApplet.java

found : java.lang.String
required: java.net.InetAddress

Socket with proxy

guys, I have a raw socket server on a local computer communicating with its client on the same machine. Unfortunately, I can not use Wireshark or Ethereal because they will only works from the local TCP point to the outside world. In my case, all is taken place locally and I want to capture those data between the local raw socket server and its client. I was told that there might be a possibility with using proxy class. Is this possible? If so, could you tell me how?
btw, there is a really cool software that does what I need:
http://www.sstinc.com/winsock.html
Unfortunately, this is only for windows :-), I need a universal solution where I can deploy my tools on any OS. Java is my answer.
Also, I can not split up the client and raw socket server onto separate machines either so I can use Wireshark. This is the way they're developed.
Oh another thing, I'd tried creating a java raw socket client which works but I can only attach to one socket port at a time at 1 TCP port. 1 TCP port is fine but I want to be able to sniff every socket ports, capturing every data packets going back and forward between the server and client. I don't know if proxy class works because I don't have a proxy anywhere installed.
Thanks in advance.

Something like this. Note I haven't even tried to compile it, it's a 2-minute hack. (You really shouldn't use this directly.)
class portlogger {
     public static void main(String[] args) throws Exception {
          int source = Integer.parseInt(args[0]); // client's target port
          int target = Integer.parseInt(args[1]); // server's actual port
          ServerSocket ss = new ServerSocket(source);
          final Socket src = ss.listen();
          final Socket tgt = new Socket("127.0.0.1", target);
          (new Thread(){
               public void run(){
                    BufferedInputStream br = new BufferedInputStream(src.getInputStream());
                    byte[] buffer = new byte[1024];
                    int bytes;
                    while((bytes = br.read(buffer)) > 0){
                         // log the client's output here, pref. in a threaded way
                         tgt.getOutputStream().write(buffer, 0, bytes);
          }).start();
          (new Thread(){
               public void run(){
                    BufferedInputStream br = new BufferedInputStream(tgt.getInputStream());
                    byte[] buffer = new byte[1024];
                    int bytes;
                    while((bytes = br.read(buffer)) > 0){
                         // log the server's output here, pref. in a threaded way
                         src.getOutputStream().write(buffer, 0, bytes);
          }).start();

Chat Applet - Sockets - Server

Hello Fellows!
I hope u all r fine..
I am facing a problem in my client/sever application. The communication is Socket Based. i.e the server is using sockets and the client which is an Applet, uses sockets to communicate with the sever.
The application is working fine in the appletviewer. i.e the applet server communication, both can send and recieve messages.
BUT
When I use IE5 the client applet can send messages to the sever but is not able to read from the specified socket...
If Any one can help me out, i will be greatfull. If u need some code segment then let me know.
Looking forward for any suggestions.
Thanking You!
Ahmad.

Thanks!
for your contribution....
but now i realised that the problem is that the client socket thread is not running.
//////////////////////// Client Applet
public class Client extends Applet implements ActionListener
Thread thRead;
ClientSocket cs;
private Panel pnlHead = new Panel();
private Panel pnlMain = new Panel();
public static Vector vtrMembers;
public void init()
thRead = (Thread) new ClientSocket();
     cs = (ClientSocket) thRead;
     vtrMembers = new Vector();
thRead.start();
cs.out.println("INI ? INI");
////////////////////////////////////////Client scoket class
public class ClientSocket extends Thread
// public static Socket sClient;

// A character-input stream to read from the socket.
public static BufferedReader in;
// A text-output stream to write to the socket.
public PrintWriter out ;
// String to store the input from the client
String strText;
// Boolean Flag to Check the read value
public boolean bFlag = true;
public ClientSocket ()
     try
     sClient = new Socket ("Ahmed" , 4000);
     // Initializing the Input straem used to read the socket.
in = new BufferedReader(new InputStreamReader(sClient.getInputStream()));
     // Initializing the Output straem used to write on the socket.
     out = new PrintWriter(sClient.getOutputStream(), true);
     catch (UnknownHostException uhe)
//     System.out.println (" Unknown Host Exception : " + uhe);
     catch (IOException ioe)
//     System.out.println (" I/O Exception : " + ioe);
public void run()
     for (;;)
     if (bFlag == true)
     Client.txtTry.setText("TRUE");
     else
     Client.txtTry.setText("False");
thRead.start() statment is executed but the thread does not stat running
because the text value is not set on the Client Applet.

Problem with SSL socket(SSLSocketFactoryImpl.createSocket())

Hello,
I'm trying to create a ssl socket but I get an exception, I really don't know why. I have alredy include the certificate via keytool to my jdk. And I'm able to get html header with URLConnection with the code below
import java.net.URL;
import java.net.URLConnection;
public class testClass {
     public static void main(String[] args) throws Exception {
          try{
               URL url = new URL("https://ippbx1:8443/axl/");
               String userPassword = "****" + ":" + "****";
               String encoding = new sun.misc.BASE64Encoder().encode (userPassword.getBytes());
               URLConnection c = url.openConnection();
               c.setRequestProperty("Authorization", "Basic " + encoding);
               for (int i=0; ; i++)
                    String name = c.getHeaderFieldKey(i);
                    String value = c.getHeaderField(i);
                    if (name == null && value == null)     // end of headers
                         break;
                    if (name == null)     // first line of headers
                         System.out.println("Server HTTP version, Response code:");
                         System.out.println(value);
                         System.out.print("\n");
                    else
                         System.out.println(name + "=" + value);
          catch (Exception e) {}
}and I get the following result :

               Socket socket = socketFactory.createSocket(address, portnum);

the server socket is a Cisco callManager Service(AXL Web Service) which receives and html+SOAP request and sends back an xml response and this server socket is running correctly with no problem.
Thanks for your help.

Thanks for your reply.
I now can access to my socket and get the information I want with:
SocketFactory socketFactory = SSLSocketFactory.getDefault();
               socket = (SSLSocket) socketFactory.createSocket("ippbx1", 8443);In fact the problem was a username/password issue.
Thanks.I quote from reply #1 "The address is just "ippbx1" and not "https://ippbx1:8443/axl/". The protocol is not part of the IP address.".
