How to set proxy for client-server socket connection?

Hi,
I'm using the code found on the following page to create a client (mobile) to server (pc) connection and send a text message.
http://javafaq.nu/java-example-code-503.html
This works with mobile operators without proxy, but does nothing when the operator uses a proxy. The question is, exactly how to set the proxy and port values for using that code.
Any help is greatly appreciated, thanks,

It's part of the cellular settings, and is usually set up by your 3G provider. You can't choose your own proxy server

How to set proxy for mail with Gmail account

Hi, I'm using mail and set up a Gmail pop account. My mac is behind a proxy, say 192.168.0.1:808. I set the system http and https with the above address and can browse the internet with safari. But the mail app cannot receive or send any mails from the google pop/smtp server. Do you know how I can set the proxy for mail so that it can send and receive mail? Thank you very much!

I solved this problem myself by using an app called proxifier. It's a tunneling tool I guess.

Best practice for client-server(Socket) application

I want to build a client-server application
1) On startup.. client creates connection to Server and keeps reading data from server
2) Server keeps on sending different messages
3) Based on messages(Async) from server client view has to be changed
I tried different cases ended up facing IllegalStateChangeException while updating GUI
So what is the best way to do this?
Please give a working example .
Thanks,
Vijay

Hi EJP,
Thanks for the suggestion ,
Here is sample code :
public class Lobby implements LobbyModelsChangeListener{
    Stage stage;
    ListView<String> listView;
    ObservableList ol;
     public Lobby(Stage primaryStage) {
        stage = primaryStage;
           ProxyServer.startReadFromServer();//Connects to Socket Server
         ProxyServer.addLobbyModelChangeListener(this);//So that any data from server is fetched to Lobby
        init();
    private void init() {
          ProxyServer.getLobbyList();//Send
        ol = FXCollections.observableArrayList(
          "Loading Data..."
        ol.addListener(new ListChangeListener(){
            @Override
            public void onChanged(Change change) {
                listView.setItems(ol);
     Group root = new Group();
    stage.setScene(new Scene(root));
     listView = new ListView<String>();
    listView.maxWidth(stage.getWidth());
     listView.setItems(ol);
     listView.getSelectionModel().setSelectionMode(SelectionMode.SINGLE);
    istView.setOnMouseClicked(new EventHandler<MouseEvent>(){
            @Override
            public void handle(MouseEvent t) {
//                ListView lv = (ListView) t.getSource();
                new NewPage(stage);
     root.getChildren().add(listView);
     @Override
    public void updateLobby(LobbyListModel[] changes) {
//        listView.getItems().clear();
        String[] ar = new String[changes.length];
        for(int i=0;i<changes.length;i++)
            if(changes!=null)
System.out.println(changes[i].getName());
ar[i] = changes[i].getName();
ol.addAll(ar);
ProxyServer.javaProxyServer
//Implements runnable
public void run()
     ......//code to read data from server
//make array of LobbyListModel[] ltm based on data from server
     fireLobbyModelChangeEvent(ltm);
void addLobbyModelChangeListener(LobbyModelsChangeListener aThis) {
this.lobbyModelsChangeListener = aThis;
     private void fireLobbyModelChangeEvent(LobbyListModel[] changes) {
LobbyModelsChangeListener listner
= (LobbyModelsChangeListener) lobbyModelsChangeListener;
listner.updateLobby(changes);
Exception :
java.lang.IllegalStateException: Not on FX application thread; currentThread = Thread-5
         at line         ol.addAll(ar);
But ListView is getting updated with new data...so not sure if its right way to proceed...

JavaFX as a SaaS/ How good is it for Client-Server work?

I was under the impression that FX could be used to produce a Client-Server application as well as SaaS.
a member of another forum said "I'm sure you meant to say "Desktop". JavaFX will not be making inroads on the web as a client-side technology."
To which I said
There have been examples of FX used with EE
http://www.oracle.com/technetwork/java/javafx/samples/index.html
http://docs.oracle.com/javafx/2/overview/jfxpub-overview.htm
Sales Dashboard (DataApp)
DataApp is a client-server application for a fictional global automobile company called Henley Car Sales. Automobile sales are simulated on an EJB server using JavaDB, and the data is available via Derby and a RESTful web service. The client demonstrates a variety of data presentations by using a mix of FXML and JavaFX.
I thought originally that JavaFX was "Desktop" only also, until I found this example. I couldn't get it to run due to some weird Database line read issue that others also had. I'm not sure if this is now due to FX's integration, or if this was something new, but I believe I have seen another FX client-server app as well.
I'm not that familiar with the client-server side of Java yet, so if you have other Information I would like to know, because I am looking to design a Client-Server app with FX, and I don't see why it would be an issue, unless there are huge limitations."
He ended up saying "Those are still desktop apps. Sure, they are client-server in that they connect to a remote database. But they are still traditional fat-client apps rather than web-based thin-client SAAS web applications which, these days, most people will think of when you say "client".
My point is to be more precise when you use the word "client".
But if your point is just that JavaFX is taking over from Swing for the limited areas in which Swing is used, I have no insight into that area."
Now I don't really like attitudes when I get my question answered, but the high and mighty needs to stop. It clearly says Client-Server so I don't know why it's being denounced by this dude who thinks he obviously knows better.
Anyways he talks about it only being able to connect to a DB, to which it says it uses EE tech such as EBJ, Restful, and Derby, so that's more than just DB right(I don't know since I havent' learned that yet)?
It seems as if he's saying that only EE code can go up on a server? Or can SE code go up there as well?
I'm looking to design a SaaS software with FX, so if this isnt' possible I would like to know possible other options(or just having all of the gui work on the client, and the rest on the backend)???
Thanks!

This response is not a tutorial, I hope it gives you some verbiage to use in further searches.
SaaS to me means that the service is running on the server. If you have the server and permission to run java apps there then you can use Java FX by having the server shuttle requests to the Java FX app. But this is probably not the intent of Saas (it would be more appropriate to use a java implemented web service).
If you are using Netbeans then it is very easy to create demo projects; use "File/New Project" to run them on your local computer.
Example File/New Project/Java Web/Web Application will give you a hello world web site very quickly. This will 1) start either tomcat or glassfish as the server. 2) launch an html page with "hello world". then you can use java script to talk with the server via ajax. Using this approach you are going to need to study JSP or J2EE stuff.
After this is running you could start one of the Java Fx examples in Netbeans: File / New Project / Samples / WebViewBrowser. This will start a javaFX app that acts like a browser and runs on the client.
So, start the "hello world" app in netbeans by right clicking it in the project pain and selecting "debug". Then start the webviewBrowser app the same way to load that web page that has "hello world" in it as all browsers do. In the WebviewBrowser (which is java fx) you can get at the javascript in the web page and do all kinds of stuff. You'll need to search for webviewBrowser examples.
The above all assumes a Netbeans solution. But, as you probably know, there are no rules. The server can be in C++ and the client in C (or any other language). The server and client usally communicate via http or tcp. So you could have a server written in java (maybe J2ee or you can rewrite a http server from scratch which isn't that hard - search for "HttpServletRequest and HttpSession" ) and the client can be in Java FX (where the Java FX talks directly with the server via http (no javascript or web page in the middle) again there are probably hundreds of libraries to talk to a http server).
I use HttpServletRequest and HttpSession on the server side with MySQL and xml. On the client I use javaScript but I am moving to a strictly Java FX solution. This will give me close to 100% java on both sides and for my purposes this will work. (I may need a little html in the middle for drag and drop installation.) I am hoping that work continues with porting Java FX to most devices: Android, IOS, WinPhone. It is already on Linux, Windows Desktops and Mac.

How to set proxy for the programme

Hello Everyone
I am learning Java Network programming. My connection to Internet has a proxy. When I use URL class to download the information from Internet, it cannot work. I think maybe I have not set the proxy in the programme. Does anybody know how to set it?
Best wishes

Publishing .fla project including client - server socket connection

Hi,
I have designed with Adobe Flash Professional CS5 a .fla project that integrates a client - server connection.
After publishing it, I have the following issue:
- when running the generated .exe file for Windows, then the connection to the server works perfectly
- but when I am running the published .html file, then nothing is sent to the server.
I have tried to change the Publish Settings.
When setting the Local Playback Security in Flash menu to "Access network only" instead of "Access local files only" then the last packet that was send using the .exe file is resent once and that's all (the html client does not receive the response from the server and the next connection attemps generate data transfer).
I guess I have to change some security settings somewhere but I didn't find which.
Does anybody have a hint ?
Thanks.

Hi again,
I was finally able to solve the issue.
I did not get any error message when using firefox, but using iExplorer provided me this error:
"Local-with-filesystem SWF files are not permitted to use sockets"
Googling did then allow me to find the solution here:
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.htm l
The local locations on which I store my html page during the development has to be added to the trusted locations in the global security settings.
Hope it will help some other people.
Best regards

How to set Proxy for IE 8.0 on doing Load Testing with OATS 12.1.0.2

I have tried adding proxy server by adding the address to "Localhost" and Port as 8080.
but nothing is working out, for recording an EBS instance its working fine ,no need to setup anything in the OATS tool, eg, Proxy settings.
But when it comes to BPM with ADF technology , the recorder is not starting the Recording even the pointer navigation also not wokring.
So, is there way to record the ADF applications in BPM ?
Thanks in advance.

Hi Wayne,
Thing is do we need to add the proxy server here?, as for doing Load testing on EBS application,there is no need of adding a proxy server,
So the same way it should work with the ADF application too, but its not showing any mouse pointer in the Browser tool bar or recording
the navigation.
Point to be noted is, we need to connect to VPN in order to access the Application.
is it because of VPN connection that its not recording?
But while doing the functional testing I didn't face anyproblem though as its recording everything even if we are connected to VPN.
In Functional testing also i found ,all the input fields where we add the "username" or any input data via a "text box" the tool is not able to
record the field information along with the input we enter.
If you could let me know ,how to do a Load testing for ADF application using BPM , it would be helpful
Thanks

How to set Proxy for iTunes Store?

I work in my office behind firewall... I have set the proxy in the Network->Proxies in all the options along with my username and password.
My iTunes is able to show my Store (India), but when I try to sign-in. It give following error
"We could not complete your iTunes Store request."
"You must log in to the proxy server in order to access the iTunes Store."
I couldn't find in iTunes->Preferences... any field to enter my proxy username/password.
Please help to resolve this issue.
Thanks.

I'm having the same problem here in the US. I'm behind a corporate firewall. Proxy settings are correct and I can connect to any web page, but I can't log into the iTunes store.
I can log into the store on my office PC which has the same proxy settings and is on the same network.. but my PC won't recognize my iPhone due to external device blocking software. I was hoping 8.2 would fix this problem.... any suggestions???????

Thank You in advice
null

you can create method on Application Module and to Client listener
like
    public Object[] getData(Number n,Date d)
Object val[]= new Object[2];
String sp = "{? = call get_data(?,?,?)}";
            Connection conn = null;
            CallableStatement proc = null;
            try {
             //   conn = isConnSupplied ? userConn : ResourceManager.getConnection();
                proc = getDBTransaction().createCallableStatement(sp,0);
            proc.registerOutParameter(1, OracleTypes.Number);
            proc.setObject(2,12);
           proc.setObject(3,dateobj);
          proc.registerOutParameter(2, OracleTypes.VARCHAR);
            proc.executeQuery();
             int amttext= proc.getInt(1); //for return value
String msg=proc.getString(2);//for out param
val[0]=amttext;
val[1]=msg;
            catch(Exception e)
                System.out.println(e);
return val;
}and access this method from backing bean using following code-
            BindingContext bindingctx=BindingContext.getCurrent();
               BindingContainer binding=bindingctx.getCurrentBindingsEntry();
            OperationBinding operationBinding1 = binding.getOperationBinding("getData");
            operationBinding1.getParamsMap().put("n",anyno);
            operationBinding1.getParamsMap().put("d",dateobj);
            operationBinding1.execute();
            String vval[] =(String[])operationBinding1.getResult();

All outgoing traffic needs to use the proxy wwwproxy (alias to http://proxypac/proxy.pac) on port 80, where it will prompt for valid authentication before allowing to get through.
There is no problem pinging www.yahoo.com from this system.

How to set password for BPEL domain

Hi,
I am new to SOA.
I want to setup client-server environment for few developers.
I installed SOA 10.1.3.3 in the server machine.
And I created few domains in BPEL, one for each developer.
It didn't ask me to set the password while creation of the domain.
Please let me know how to set password for newly created domain so that each developer login to his/her own domain and manage processes.
Thanks!!!

Thanks for the prompt response.
What roles should I give to my developers to allow them to manage their services in ESB control, BPEL control, WSM control.
And I would like to know how to set the password for a BPEL domain too.

FU Ant task failure: java.util.concurrent.ExecutionException: could not close client/server socket

We sometimes see this failure intermitently when using the FlexUnit Ant task to run tests in a CI environment. The Ant task throws this exception:
java.util.concurrent.ExecutionException: could not close client/server socket
I have seen this for a while now, and still see it with the latest 4.1 RC versions.
Here is the console output seen along with the above exception:

I am not sure if this information will help everyone, but here goes...
For us, these problems with FlexUnit tests crashing the Flash Player appear to be related to couple of factors. Recently, we moved up from Flex 3.2 to Flex 4.1 as our development baseline. Many people complained that their development environment (Flash Builder, etc.) was much more unstable. Apparently, 4.1 produces SWFs that require more memory to run than 3.2 does? Anyway, we still had Flash Player 10.1 as our runtime baseline. Apparently, that version of the player was not as capable of running larger FlexUnit test SWFs, and would crash (as I posted months earlier). I upgraded to the latest 10.3 standalone player versions, and the crashes have now ceased. It would be nice to know exactly what was causing the crashes, but memory management (or lack of) is my best guess.
So, if you are seeing these issues, try upgrading to the latest Flash Player version.
Regards,
Trevor

Use of servlet http tunneling for client server communication

Hello I am having a problem connecting a simple client applet to a server application. I can connect the two directly using sockets. However, when I try to connect the two via a servlet the input stream cannot be accessed. The application is purely for demonstration. Here is some of the source code

Hi,
In your client you are trying to open OutputStream even though you are not using it.
So there are two solutions here.
1. If you dont need OutputStream your code shoud look like this
try {
// Step 1: Create a Socket to make connection.
display.setText( "Attempting connection\n" );
URL currentpage = getCodeBase();
String protocol = currentpage.getProtocol();
String host = currentpage.getHost();
int port = 8100;
String urlsuffix = "/servlet/SocketServlet";
URL dataurl = new URL( "http://localhost:8100/servlet/SocketServlet" );
connection = dataurl.openConnection();
//connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestProperty("Content-type", "application/octet-stream");
connection.setUseCaches( false );
display.append( "\nConnected to: " + host );
// Step 2: Get the output streams.
//output = new DataOutputStream(
//connection.getOutputStream() );
//display.append( "\n got output stream\n" );
display.append( "\n Not interested in output stream\n" );
//Step 3 Inpustream related
// Step 4: Close connection.
display.append( "Closing connection.\n" );
//output.close();
input.close();
1. If you need OutputStream, close your OutputStream before even trying to get InputStream, your code should like this
try {
// Step 1: Create a Socket to make connection.
display.setText( "Attempting connection\n" );
URL currentpage = getCodeBase();
String protocol = currentpage.getProtocol();
String host = currentpage.getHost();
int port = 8100;
String urlsuffix = "/servlet/SocketServlet";
URL dataurl = new URL( "http://localhost:8100/servlet/SocketServlet" );
connection = dataurl.openConnection();
//connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestProperty("Content-type", "application/octet-stream");
connection.setUseCaches( false );
display.append( "\nConnected to: " + host );
// Step 2: Get the output streams.
output = new DataOutputStream(
connection.getOutputStream() );
display.append( "\n got output stream\n" );
//I'll do whateve I've to do with outputstream
//done with output stream closing
output.close();
//Step 3 Inpustream related
// Step 4: Close connection.
display.append( "Closing connection.\n" );
//output.close();
input.close();
hope this works
all the best,
Raj
