I'm trying to write a XMPP client to connect to Quickblox and use it as a bot for a chat application. I'm using Smack 4.1.3 for this purpose. Here's my code:
public static void sendChat1() {
XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
.setUsernameAndPassword("4461610-26179", "pass")
.setServiceName("chat.quickblox.com")
.setPort(5222)
.build();
System.out.println("Establishing Connection");
AbstractXMPPConnection conn2 = new XMPPTCPConnection(config);
try {
conn2.connect();
} catch (SmackException e) {
System.out.println("ERROR");
e.printStackTrace();
} catch (IOException e) {
System.out.println("ERROR");
e.printStackTrace();
} catch (XMPPException e) {
System.out.println("ERROR");
e.printStackTrace();
}
MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(conn2);
System.out.println("Creating multi user chat room");
MultiUserChat muc = manager.getMultiUserChat("26179_55b76303535c12544b00b550#muc.chat.quickblox.com");
System.out.println("Joining chat room");
try {
muc.join("4461610");
} catch (XMPPException.XMPPErrorException e) {
System.out.println("ERROR");
e.printStackTrace();
return;
} catch (SmackException e) {
System.out.println("ERROR");
e.printStackTrace();
return;
}
System.out.println("Chat room request");
try {
muc.sendConfigurationForm(new Form(DataForm.Type.submit));
} catch (SmackException.NoResponseException e) {
System.out.println("ERROR");
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
System.out.println("ERROR");
e.printStackTrace();
} catch (SmackException.NotConnectedException e) {
System.out.println("ERROR");
e.printStackTrace();
}
}
public static void main(String[] args) {
sendChat1();
}
For some reason, I'm unable to make the client connect to a chat room using MultiUserChat. Here's the output when I run this code:
Establishing Connection

The app configuration on quickblox seems correct as well. I've created a user that I'm using in this app. I've also created a public dialogue that is being used in this app as well. Not sure what's going on here.
Btw, I cannot use the SDKs provided with Quickblox since I've to deploy this code on my web server which is built on a java framework.
improper-addressing error says what it says
This jid is strange 4461610-26179#chat.quickblox.com#chat.quickblox.com
it should be just 4461610-26179#chat.quickblox.com
that's why you receive this error
I don't see where it could be a problem with this in your code, anyway please check such a possibility

i am unable to upload file on xmpp using smack client android. slot.puturl() returns "https://localhost:7443/httpfileupload/27c97df7-dbbf-47ff-b19a-3ac624e51cf0/1.jpg"
HttpFileUploadManager manager = HttpFileUploadManager.getInstanceFor(mConnection);
try {
Slot slot = manager.requestSlot(path, 10000);
uploadFileToSlot(new File(path), slot);
} catch (InterruptedException e) {
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
} catch (SmackException e) {
e.printStackTrace();
}
I got solution for after very deep research.
That HttpFileUploadManager is only for requesting slot from server.
Once you got slot request url upload file using httpclient or okhttpclient.
For okhttpclient:
You need to configure sslSocketFactory by mtm or certificatepinning.
OkHttpClient.Builder okHttpClientBuilder = new OkHttpClient().newBuilder();
SSLContext sslContext = JavaPinning.forPin(<PINNING_VALUE>);
okHttpClientBuilder.writeTimeout(5, TimeUnit.MINUTES)
.connectTimeout(5, TimeUnit.MINUTES)
.readTimeout(5, TimeUnit.MINUTES);
okHttpClientBuilder.sslSocketFactory(sslContext.getSocketFactory(), JavaPinning.trustManagerForPin(<PINNING_VALUE>));
OkHttpClient client = okHttpClientBuilder.build();
initiate okhttpclient and add file like.
Request request = new Request.Builder()
.url(slot.getPutUrl())
.put(RequestBody.create(MediaType.parse("application/octet-stream"), files))
.build();
Now lets begin to upload.
client.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(final Call call, final IOException e) {
// Handle the error
Log.i(log, "error " + e);
}
#Override
public void onResponse(final Call call, final Response response) throws IOException {
if (!response.isSuccessful()) {
// Handle the error
Log.i(log, "errored " + response);
}
Log.i(log, "success " + response);
// Upload successful
}
});
Hope it helps you.
When /api/upload REST endpoint is accessed I have a UploadController that uses a service UploadService to upload a file to an ftp server with org.apache.commons.net.ftp.FTPClient. I would like to be able to send information back to the user if the ftp client was unable to connect or timed out, or successfully sent the file. I have some IOException handling, but I don't know how to turn that around and send it back to the front-end. Any help appreciated, thanks!
public void upload(InputStream inputStream) {
String filename = "file.txt"
client = new FTPClient();
try {
client.connect("ftpsite");
client.login("username", "password");
client.storeFile(filename, inputStream);
} catch (IOException ioe) {
ioe.printStackTrace();
} finally {
try {
if (inputStream!= null) {
inputStream.close();
}
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
return null;
}
You should throw a new Exception in your catch statement.
For example, you could create a RequestTimeoutException class:
#ResponseStatus(HttpStatus.REQUEST_TIMEOUT)
public class RequestTimeoutException extends RuntimeException { }
and then throw it when need be:
catch (IOException ioe) {
//do some logging while you're at it
throw new RequestTimeoutException();
}
I am trying to send the images captured from client to server,images are captured using robot class and writing to client socket.

Server Console

Image capture from client success...!

Hello

Repeat like this.This code works perfectly for first time after that it fails.Each time runs it capture the images only once.What change i have to make to capture and write the images at regular intervals...Please help me
Try this in ClientDemo.java
while(true)
{
System.out.println("Hello");
Socket client=new Socket("localhost", 6666);
Thread th=new Thread(new ClientThread(client));
th.start();
System.out.println("Thread started........");
th.sleep(1000*60);
}
And make sure that you close the client socket once the thread(ClientThread.java) is completed may be in finally block or at the end of code.
You don't need ImageIO for the server end of this. Just send and receive bytes:
while ((count = in.read(buffer()) > 0)
{
out.write(buffer, 0, count);
}
I see the problem is in the server. The first time it accepts a connection from the client,Thread ts=new Thread( new ServerThread(serversocket.accept())); but the client only connects once Socket client=new Socket("localhost", 6666); When the first transfer is completed the server stay again in the accept waiting for the client to make the connect which never happen again. Therefore either you should issue only one accept and use that socket for every transfer or close both sockets, at the client and server, and make the accept/connect again.
In my application I want to post from my android application XML data in the remote server which is using REST service. My code is below:
String url = "api.example.com";
int port = 443;
String query = "<?xml version='1.0' encoding='UTF-8'?><request><client><name>APIappDevAccount</name><password>123456</password></client><user><name>foyzulkarim</name><password>123456</password><groupId>12345</groupId></user></request>";
Socket socket = null;
try {
socket = new Socket(url,port);
} catch (UnknownHostException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
} catch (IOException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
BufferedReader br = null;
try {
br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
PrintStream pw = null;
try {
pw = new PrintStream(socket.getOutputStream());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
pw.print("POST api.example.com/rest/rest/user");
pw.print("Content-Type: application/xml");
pw.print("Content-Length:" + query.length());
pw.print(query);
System.out.println("hello foysal.");
//get result
String l = null;
String text="";
try {
while ((l=br.readLine())!=null) {
System.out.println(l);
text+=l;
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
pw.close();
try {
br.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
But that server is behind SSL/HTTPS protocol so i am getting the below 400 Bad Request as response.
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"><html><head><title>400 Bad Request</title></head><body><h1>Bad Request</h1><p>Your browser sent a request that this server could not understand.<br />Reason: You're speaking plain HTTP to an SSL-enabled server port.<br />Instead use the HTTPS scheme to access this URL, please.<br /><blockquote>Hint: <b>https://api.example.com/</b></blockquote></p></body></html>
If I use SSLSocketFactory like below
SocketFactory socketFactory = SSLSocketFactory.getDefault();
Socket socket = null;
try {
socket = socketFactory.createSocket(url, port);
I got exception
javax.net.ssl.SSLException: Not trusted server certificate
java.security.cert.CertPathValidatorException: TrustAnchor for CertPath not found.
at line
br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
My question is, how can i post the data over SSL from android application in my above scenario?
I guess many of us are facing this problem, so I am requesting you to give me/us some elaborated answers.Cheers.
Too many unknowns :-)
Try plain HTTP against a test server you have control over.
My hunch is it will give the same error.
You don't seem to put an empty line between the HTTP headers and body for example.
Why are you re-implementing HTTP anyway? Don't tell me there's no API or library you could use on whatever platform this is? Usually there's java.net.HttpUrlConnection, or Apache HttpClient.
Edit:
Hey, look what google brought in: http://developer.android.com/reference/android/net/http/AndroidHttpClient.html
It seems that I needed to add the TrustAnchor certificate to be able to validate the whole key chain.
I have requested about this certificate to my API Provider and they given me the web link from where I can get the certificate. [i have changed the web link for confidentiality]
https://www.example.com/library/......SSL_bundle.pem
They also told me to get try the connection via (i guess it should be executed from command prompt)
openssl s_client -connect api.example.com:443 -CAfile /root/SSL_bundle.pem
I then have to integrate the certificate into my application.
I will now try to know how can I integrate that certificate, but that discussion should be in another question.
I have done it. The code is given below.
private String executeRequest(String targetURL, final String requestMethod,
String soap_request_message_header, String soap_request_message_body) {
URL url;
HttpURLConnection connection = null;
try {
url = new URL(targetURL);
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod(requestMethod);
connection.setRequestProperty("SOAPAction",
soap_request_message_header);
connection.setUseCaches(false);
connection.setDoInput(true);
connection.setDoOutput(true);
// Send request
DataOutputStream wr = new DataOutputStream(connection
.getOutputStream());
wr.writeBytes(soap_request_message_body);
wr.flush();
wr.close();
// Get Response
InputStream is;
final int responseCode = connection.getResponseCode();
Log.i("response", "code=" + responseCode);
if (responseCode <= 400) {
is = connection.getInputStream();
} else {
/* error from server */
is = connection.getErrorStream();
}
// is= connection.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
String line;
StringBuffer response = new StringBuffer();
while ((line = rd.readLine()) != null) {
response.append(line);
response.append('\r');
}
rd.close();
Log.i("response", "" + response.toString());
return response.toString();
} catch (Exception e) {
Log.e("error https", "", e);
return e.getMessage();
} finally {
if (connection != null) {
connection.disconnect();
}
}
}
I have tried in many different ways to send my xml document over a socket connection between a server and a client without closing the socket after sending (keep the outputstream open, for sending another document). I have found several sites who claimed that it should work, so I tried it in all the ways they sugested, but I did not found a way which works.
(that describes the same what I would like to do: http://jaxb.java.net/guide/Designing_a_client_server_protocol_in_XML.html)
The follwing code works perfectly if I am closing the socket after sending (#code marsh.marshal(element, xsw);), but it stucks on unmarshaling on the server side, if I try to keep the socket open.
