Problem with Socket and public IP

Hi.
I was create a program to tchat with my friend.
This program turn good in à local network but i obtain
A Connection refused: connect exception when I want
to communiqué by internet :
I write
Socket client = new Socket("my public IP",12347);And I was configurate my router to mapping 12347 port.
Help me please.

the exception is :
Connection refused: connect
 at java.net.PlainSocketImpl.socketConnect(Native Method)

Problems with sockets and InputsStreams

Hi,
I ve this code:
InputStream is = null;
boolean ok=true;
while(ok){
//sc is an object instance of socketConnection
is = sc.openInputStream();
return this.parse(is);
//is.close();
return "";
and this exception is produced:
java.io.IOException: no more Input Streams available.
This exception is produced in the line:
is = sc.openInputStream();
I m connecting to a server and this server sends data throw a socket... but the problem is that when i m reading from this socket and this socket doesn t have data in it...
how could i solve this problem...?
Thanks,
Diego

That would be the "real" code:
public String process()throws IOException{
InputStream is = null;
is = sc.openInputStream();
String result= this.parse(is);
is.close();
any suggestions?
Thanks,
Diego

Problem with socket and object writing

Hi,
I programm this client/server app, the client has a point (graphic ) , the server has a point and when the mouse is moving it moves the point and the new position is send via the socket.
The probleme is that i don't receive the good thing.
When i display the coord of the point before sending it's good , but when receiving from the socket the coords are always the same ...
i don't understand .
Well , try and tell me ...
Thx.

oups, the program can be usefull ...

Problem with Socket and dynamic IP

The problem I have is the following: My domain has a dynamic IP, so after the IP changes the s.accept() does not work any more!
try // Point 1 *)
ServerSocket s = new ServerSocket(portNumber);
for(;;)
Socket incoming = s.accept(); // does not work after IP changes
new ThreadedEchoHandler(incoming, i).start();
So I have to detect that the IP has changed and have to start again at Point 1
How can I do this?
thx walter

Something is vary wrong with your network software if your getting an error on that.
When you start your computer connected to the network, a DHCP (in your case) Server sends your NIC a dynamic IP address, we call this process "binding". When the client computer connects it also is given an IP address to bind to. You can't connect to anything, or in your case create a ServerSocket, if you dont even have an IP. So your Server has an IP address, and so does the client. You should not be getting any errors unless the client/server network is using two different protocols. You can't run an IPX/SPX network and a TCP/IP network together without a Bridge.
That does not seem to be your problem. I believe, then, that the problem is that your ThreadedEchoHandler is holding the CPU. Instead of having a client connect (s.accept()) outside of that thread. Have the thread be created by using the arugment of the ServerSocket instead and no the Socket object created.
new ThreadedEchoHandler(ServerSocket ss);
Then let it do it's thing. Also, you will need to call it's start() method to actually run the thread as a thread. Otherwise it runs as a simple class.

Problem with socket and Threads

Hi,
I have coded a package that sends an sms via a gateway.
Here is what is happening:
* I create a singleton of my SMSModule.
* I create an sms object.
* I put the object in a Queue.
* I start a new Thread in my sms module that reads sms from queue.
* I connect to sms gateway.
* I send the sms.
* I disconnect from socket! This is where things go wrong and I get the following error (see below).
I have a zip file with the code so if you have time to take a look at it I would appreciate it.
Anyway all hints are appreciated!

Off the top of my head, probably the garbage collector cleared your SMSModule coz all classes loaded through other classloaders will be unloaded when that classloader is unloaded.

Problem with socket and Flash

I have a chat application where the client is written in Flash 9 and it connects an XMLSocket to my java server.
Those that know Flash 9 know that it first makes a policy file request and all you have to do is provide a small chunk of xml stating the desired port and domain.
To get a better understanding I adding some thread tracking to the server app. Now when I run the following:
String policy_response = "<?xml version=\"1.0\"?><cross-domain-policy><allow-access-from domain=\"*\" to-ports=\"6000\" secure=\"false\" /></cross-domain-policy>"+ "\0";
ErrorBroker.addError("name: " + this.currentThread().getName());
String mes = "";
if(cs.incoming.ready())
 mes = cs.readln();
 ErrorBroker.addError( this.currentThread().getName()+ " ready: " + mes);
if(mes.equals("<policy-file-request/>" + "\0"))
 ErrorBroker.addError( this.currentThread().getName()+ " policy hit");
 cs.send(policy_response);
counter++;
ErrorBroker.addError( this.currentThread().getName()+" counter: " + counter);and the results I get are the following:
name: Thread-34
Thread-34 in ready: <policy-file-request/>
Thread-34 policy hit
Thread-34 counter: 1
Thread-34 after read2: <policy-file-request/>
END OF processClient()
Closing socketThere is no second connection though there should be. On the flash end I get nothing..no message stating a connection made or lost.
Now if I have the server as such:
ErrorBroker.addError("name: " + this.currentThread().getName());
String mes = "";
/* ---- policy response sent BEFORE readLine() ---- */
cs.send(policy_response);
if(cs.incoming.ready())
 mes = cs.readln();
 ErrorBroker.addError( this.currentThread().getName()+ " in ready: " + mes);
if(mes.equals("<policy-file-request/>" + "\0"))
 ErrorBroker.addError( this.currentThread().getName()+ " policy hit");
counter++;
ErrorBroker.addError( this.currentThread().getName()+" counter: " + counter);The one difference being that the policy reply happens before any read.
I get these results:
name: Thread-34
Thread-34 in ready: <policy-file-request/>
name: Thread-35
Thread-34 policy hit
Thread-35 counter: 1
Thread-34 counter: 2
Thread-35 after read2:
Thread-34 after read2: <policy-file-request/>
io error1: java.lang.StringIndexOutOfBoundsException:String index out of range: 0
END OF processClient()
END OF processClient()
Closing socket
Closing socketDoes this make sense to anyone? How is it that if I do a readLine before sending the policy request file that nothing happens but I send after a readLine the second socket shows up.
Any help is GREATLY appreciated.

The second case does appear to be a threading issue.....but what bothers me the most is why I get nothing from flash when I readLine first. This doesn't seem to be an issue with anyone else and I've seen many examples (though almost all were written in PHP) that are exactly the same. Read first...look for the policy request...then reply accordingly.
This is a small chat application running on Tomcat 5.5.
It worked well back when I ran it with Flash 8 but since I upgraded to Flash 9 (had to...no other way around) I now have to deal with this policy issue (apparently it pissed off quite a few developers).

Problems with sockets and hex code

When i try to send 0x9d on socket, it send 0x3f. Why?
conexion = new Socket("server", 0000);
escritura = new PrintWriter( conexion.getOutputStream(),true);
escritura.write(0x9d);
escritura.print("\u009d");
It always send 0x3f.

It always send 0x3f.My guess is 0x3f is a question mark, and since you're using PrintWriter which is geared for printing "strings" and the character 0x9d is not in the selected (default, since you didn't specify one) character encoding, it turns it into a question mark.
Solution: Don't use PrintWriter for sending binary data.

Problem with JFrame and busy/wait Cursor

Hi -- I'm trying to set a JFrame's cursor to be the busy cursor,
for the duration of some operation (usually just a few seconds).
I can get it to work in some situations, but not others.
Timing does seem to be an issue.
There are thousands of posts on the BugParade, but
in general Sun indicates this is not a bug. I just need
a work-around.
I've written a test program below to demonstrate the problem.
I have the problem on Solaris, running with both J2SE 1.3 and 1.4.
I have not tested on Windows yet.
When you run the following code, three JFrames will be opened,
each with the same 5 buttons. The first "F1" listens to its own
buttons, and works fine. The other two (F2 and F3) listen
to each other's buttons.
The "BUSY" button simply sets the cursor on its listener
to the busy cursor. The "DONE" button sets it to the
default cursor. These work fine.
The "SLEEP" button sets the cursor, sleeps for 3 seconds,
and sets it back. This does not work.
The "INVOKE LATER" button does the same thing,
except is uses invokeLater to sleep and set the
cursor back. This also does not work.
The "DELAY" button sleeps for 3 seconds (giving you
time to move the mouse into the other (listerner's)
window, and then it behaves just like the "SLEEP"
button. This works.
Any ideas would be appreciated, thanks.

I've had the same problems with cursors and repaints in a swing application, and I was thinking of if I could use invokeLater, but I never got that far with it.
I still believe you would need a thread for the time consuming task, and that invokeLater is something you only need to use in a thread different from the event thread.

Problem with axis2 and Tomcat

Hello,
I am having a strange problem with Tomcat and axis. I have a webservice that uses axis2 for wsdl2java class generation. When I compile my project in maven a Test is performed. During the test a glassfish server is established and the project is deployed -everything work great with the expected results. However when I try to deploy the webservice on tomcat it has some problems.
At first I tried to call axis code in a POST method that takes a MultiPart message. The code is as below:
*@Path("identifyWavestream")*
*@POST*
*@Consumes(MediaType.MULTIPART_FORM_DATA)*
*@Produces(MediaType.APPLICATION_XML)*
*public String multipartTest(com.sun.jersey.multipart.MultiPart multiPart) throws Exception {*
*// get first body part (index 0)*
*//tomcat shows that the first error is here (line 122 is the nest one with bodypart)*
BodyPart bp = multiPart.getBodyParts().get(0);
BodyPartEntity bodyPartEntity = (BodyPartEntity) bp.getEntity();
InputStream stream = bodyPartEntity.getInputStream();
*//the rest of the code either saves the incoming file or implements the wsdl2java axis interface - neither works.*
And the tomcat error is:
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

It was strange to me since this simple approach of handling a Multipart method worked for me earlier. Then I decided skip the handling of multipart method and just call the axis code. But the results also caused an error. I then tried to call the axis code in a simple @GET method (to cross out any issues regarding the multipart) and the result where the same. Again everything works on the maven- glassfish test. In this case the tomcat error is the following:

Problem with JTextPane and StateInvariantError

Hi. I am having a problem with JTextPanes and changing only certain text to bold. I am writing a chat program and would like to allow users to make certain text in their entries bold. The best way I can think of to do this is to add and tags to the beginning and end of any text that is to be bold. When the other client receives the message, the program will take out all of the and tags and display any text between them as bold (or italic with and ). I've searched the forums a lot and figured out several ways to make the text bold, and several ways to determine which text is bold before sending the text, but none that work together. Currently, I add the bold tags with this code: (note: messageDoc is a StyledDocument and messageText is a JTextPane)
public String getMessageText() {
 String text = null;
 boolean bold = false, italic = false;
 for (int i = 0; i < messageDoc.getLength(); i++) {
 messageText.setCaretPosition(i);
 if (StyleConstants.isBold(messageDoc.getCharacterElement(i).getAttributes()) && !bold) {
 bold = true;
 if (text != null) {
 text = text + "";
 else {
 text = "";
 else if (StyleConstants.isBold(messageDoc.getCharacterElement(i).getAttributes()) && bold) {
 // Do nothing
 else if (!StyleConstants.isBold(messageDoc.getCharacterElement(i).getAttributes()) && bold) {
 bold = false;
 if (text != null) {
 text = text + "";
 else {
 text = "";
 try {
 if (text != null) {
 text = text + messageDoc.getText(i,1);
 else {
 text = messageDoc.getText(i, 1);
 catch (BadLocationException e) {
 System.out.println("An error occurred while getting the text from the message document");
 e.printStackTrace();
 return text;
 } // end getMessageText()When the message is sent to the other client, the program searches through the received message and changes the text between the bold tags to bold. This seems as if it should work, but as soon as I click on the bold button, I get a StateInvariantError. The code for my button is:
public void actionPerformed(ActionEvent evt) {
 if (evt.getSource() == bold) {
 MutableAttributeSet bold = new SimpleAttributeSet();
 StyleConstants.setBold(bold, true);
 messageText.getStyledDocument().setCharacterAttributes(messageText.getSelectionStart(), messageText.getSelectionStart() - messageText.getSelectionEnd() - 1, bold, false);
 } //end actionPerformed()Can anyone help me to figure out why this error is being thrown? I have searched for a while to figure out this way of doing what I'm trying to do and I've found out that a StateInvariantError has been reported as a bug in several different circumstances but not in relation to this. Or, if there is a better way to add and check the style of the text that would be great as well. Any help is much appreciated, thanks in advance.

Swing related questions should be posted in the Swing forum.
Can't tell from you code what the problem is because I don't know the context of how each method is invoked. But it would seem like you are trying to query the data in the Document while the Document is being updated. Try wrapping the getMessageText() method is a SwingUtilities.invokeLater().
There is no need to write custom code for a Bold Action you can just use:
JButton bold = new JButton( new StyledEditorKit.BoldAction() );Also your code to build the text String is not very efficient. You should not be using string concatenation to append text to the string. You should be using a StringBuffer or StringBuilder.

Problem with writing and reading using serialization

I am having a problem with writing and reading an object that has another object in it. The purpose of the class is to write a order that has multiple items in it. And there will be several orders. This is for an IB project, where one of the requirements is to utilize a hierarchical composite data structure. That is, it is "one that contains more than one element and at least one of the elements is a composite data structure. Examples are, an array or linked list of records, a record that has one field that is another record, or an array". The code is shown below:
The error produced is

Problem with Drag and drop in panel dashboard

Hi
I am having problem with drag and drop in panel dashboard.
I will explain what i am doing.
I am using Oracle three column template in First region i am having a table that showing all customer.
I drag one record from my table and drop it on customer info (CIF) page on second region it is working fine.
my CIF page has a dashboard with 6 panel box. i am showing 6 different jsff in 6 panel box.
I put drop target in each jsff
<af:dropTarget dropListener="#{backingBeanScope.backing_customerinformation.handleItemDrop}"
actions="COPY">
<af:dataFlavor flavorClass="org.apache.myfaces.trinidad.model.RowKeySet"
discriminant="CustomerSearchDnD"/>
</af:dropTarget>
when i put drop target my panel boxes moves only when i drag it to another panel box header not entire part of panel box.
if i remove the drop target then panel box move normally as the example given on: [http://adfui.us.oracle.com:7778/faces-trunk/faces/visualDesigns/dashboard.jspx?_afrLoop=2021391022520156&_afrWindowMode=0&_afrWindowId=null] but in taht case i am not able to drag and drop my data

You must be an Oracle employee as you're referring to a component in the upcoming JDeveloper version which has yet been released to the general public. Oracle employee's are, I believe, directed to post on internal Oracle forums.

Problem with PropertyChangeListener and JTextField

I'm having a problem with PropertyChangeListener and JTextField.
I can not seem to get the propertychange event to fire.
Anyone have any idea why the code below doesn't work?
* NewJFrame.java

jTextField1.addPropertyChangeListener( this );
public void propertyChange(PropertyChangeEvent e) {
System.out.println(e);
/** This method is called from within the constructor to
* initialize the form.

getContentPane().add(jTextField1, java.awt.BorderLayout.NORTH);
jFormattedTextField1.setText("jFormattedTextField1");

private javax.swing.JFormattedTextField jFormattedTextField1;
private javax.swing.JScrollPane jScrollPane1;
private javax.swing.JTextField jTextField1;
// End of variables declaration
}

If you want to listen to changes in the textfield's contents you should use a DocumentListener and not a PropertyChangeListener:

And please use [co[/i]de] tags when you are posting code (press the code button above the message window).

Problem with Thread and InputStream

Hi,
I am having a problem with threads and InputStreams. I have a class which
extends Thread. I have created and started four instances of this class. But
only one instance finishes its' work. When I check the state of other three
threads their state remains Runnable.
What I want to do is to open four InputStreams which are running in four
threads, which reads from the same url.
This is what I have written in my thread class's run method,
public void run()
     URL url = new URL("http://localhost/test/myFile.exe");
URLConnection conn = url.openConnection();
InputStream istream = conn.getInputStream();
System.out.println("input stream taken");
If I close the input stream at the end of the run method, then other threads
also works fine. But I do not want to close it becuase I have to read data
from it later.
The file(myFile.exe) I am trying to read is about 35 MB in size.
When I try to read a file which is about 10 KB all the threads work well.
Plz teach me how to solve this problem.
I am using JDK 1.5 and Win XP home edition.
Thanks in advance,
Chamal.

I dunno if we should be doing such things as this code does, but it works fine for me. All threads get completed.
public class ThreadURL implements Runnable
    /* (non-Javadoc)
     * @see java.lang.Runnable#run()
    public void run()
        try
            URL url = new URL("http://localhost:7777/java/install/");
            URLConnection conn = url.openConnection();
            InputStream istream = conn.getInputStream();
            System.out.println("input stream taken by "+Thread.currentThread().getName());
            istream.close();
            System.out.println("input stream closed by "+Thread.currentThread().getName());
        catch (MalformedURLException e)
            System.out.println(e);
            //TODO Handle exception.
        catch (IOException e)
            System.out.println(e);
            //TODO Handle exception.
    public static void main(String[] args)
        ThreadURL u = new ThreadURL();
        Thread t = new Thread(u,"1");
        Thread t1 = new Thread(u,"2");
        Thread t2 = new Thread(u,"3");
        Thread t3 = new Thread(u,"4");
        t.start();
        t1.start();
        t2.start();
        t3.start();
}And this is the o/p i got
input stream taken by 2
input stream closed by 2
input stream taken by 4
input stream closed by 4
input stream taken by 3
input stream closed by 3
input stream taken by 1
input stream closed by 1
can u paste your whole code ?

Problems with SwingWorker and classes in my new job, ;), can you help me?

Hi all, ;)
First of all, sorry about my poor English.
I have a problem with Swing and Threads, I hope you help me (because I'm in the firsts two weeks in my new job)
I have two classes:
Form1: Its a JPanel class with JProgressBar and JLabel inside.
FormularioApplet: (the main) Its a JPanel class with a form1 inside.
I have to download a file from a server and show the progress of the download in the JProgressBar. To make it I do this:
In Form1 I make a Thread that update the progress bar and gets the fole from the server.
In FormularioApplet (the main) I call to the method getDownloadedFile from Form1 to get the File.
THE PROBLEM:
The execution of FormularioApplet finishes before the Thread of Form1 (with download the file) download the file. Then, when I call in FormularioApplet the variable with the file an Exception: Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException is generated.
First main begins his execution, then call to Form1 (a thread) then continues his execution and when the execution is finished ends the execution os Form1 and his thread.
How can I do for main class call the function and the Thread download his file after main class assign the file of return method?
How can I pass information froma class include an a main class. Form1 can't send to main (because main class made a Form1 f1 = new Form1()) any information from his end of the execution. I think if Form1 can say to main class that he finishes is job, then main class can gets the file.
I put in bold the important lines.
Note: My level of JAVA, you can see, is not elevated.
THANKS A LOT

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
iPad: Issues connecting to Wi-Fi networks http://support.apple.com/kb/ts3304
iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.
