Transferring XMPP files using smack api (receiving listener does not receive request)

Question

Hi, I am trying to send a file. But it does not run the transfer file. upon examination, I found that the listener of the receiver does not receive a request from the sender. Here is the sender code: (ruff gui codes .. just look at filetransfer thingy) import

java.awt.Color; import javax.swing.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.File; import java.text.DecimalFormat; import java.util.ArrayList; import javax.swing.JButton; import javax.swing.JComboBox; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JTextField; import javax.swing.tree.DefaultMutableTreeNode; import org.jivesoftware.smack.ConnectionConfiguration; import org.jivesoftware.smack.Roster; import org.jivesoftware.smack.RosterEntry; import org.jivesoftware.smack.SASLAuthentication; import org.jivesoftware.smack.XMPPConnection; import org.jivesoftware.smack.XMPPException; import org.jivesoftware.smackx.ServiceDiscoveryManager; import org.jivesoftware.smackx.filetransfer.FileTransfer; import org.jivesoftware.smackx.filetransfer.FileTransferManager; import org.jivesoftware.smackx.filetransfer.FileTransferNegotiator; import org.jivesoftware.smackx.filetransfer.OutgoingFileTransfer; public class FileSelectionMainGUI { ConnectionConfiguration configGoogle = new ConnectionConfiguration("jabber.org", 5222); JFrame mainWindow; JLabel selectEmailLabel,selectFileLabel; JButton browseFilesButton,sendButton; JTextField browseField; JComboBox buddyListBox; JPanel contentPanel; Roster roster; FileTransferManager fileTransferManager; XMPPConnection connection; DecimalFormat transferringProgress = new DecimalFormat("#"); XMPPFileManager receiveManager; public void createGUI() { mainWindow = new JFrame("Sender"); mainWindow.setLayout(null); mainWindow.setSize(700, 600); mainWindow.setLocation(100, 50); contentPanel = new JPanel(); contentPanel.setLayout(null); contentPanel.setBounds(0, 0, 700, 600); selectEmailLabel = new JLabel("Enter User Email ID"); selectEmailLabel.setBounds(80, 325, 150, 30); contentPanel.add(selectEmailLabel); selectFileLabel = new JLabel("Select File"); selectFileLabel.setBounds(96, 390, 150, 30); contentPanel.add(selectFileLabel); buddyListBox = new JComboBox(); buddyListBox.addItem(" [e-mail] "); buddyListBox.setBackground(Color.white); buddyListBox.setBounds(230, 325, 390, 30); contentPanel.add(buddyListBox); browseField = new JTextField(); browseField.setText("testdoc.txt"); browseField.setBounds(230, 390, 220, 30); contentPanel.add(browseField); browseFilesButton = new JButton("Browse File"); browseFilesButton.setBounds(470, 390, 130, 30); contentPanel.add(browseFilesButton); sendButton = new JButton("Send File"); sendButton.setBounds(470, 490, 130, 30); contentPanel.add(sendButton); sendButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { // TODO Auto-generated method stub try { sendFile(buddyListBox.getItemAt(0).toString(), browseField.getText()); } catch (XMPPException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); mainWindow.add(contentPanel); mainWindow.setVisible(true); } public void login(String userName,String password,String type_server) { configGoogle.setSASLAuthenticationEnabled(true); connection = new XMPPConnection(configGoogle); XMPPConnection.DEBUG_ENABLED = true; SASLAuthentication.supportSASLMechanism("PLAIN"); try { connection.connect(); connection.login(userName, password); System.out.println("logged in..."); } catch(Exception e) { e.printStackTrace(); } new ServiceDiscoveryManager(connection); fileTransferManager = new FileTransferManager(connection); FileTransferNegotiator.setServiceEnabled(connection, true); } public void sendFile(String userID, String path) throws XMPPException { OutgoingFileTransfer fileTransfer = fileTransferManager.createOutgoingFileTransfer(userID); System.out.println("status is:"+fileTransfer.getStatus()); try { fileTransfer.sendFile(new File(path), "this is the description"); System.out.println("status is:"+fileTransfer.getStatus()); System.out.println("sent .. just"); while (!fileTransfer.isDone()) { if (fileTransfer.getStatus() == FileTransfer.Status.refused) { JOptionPane.showMessageDialog(null, "Could not send the file to " + userID + ".", "Failed", JOptionPane.ERROR_MESSAGE); return; } if (fileTransfer.getStatus() == FileTransfer.Status.error) { JOptionPane.showMessageDialog(null, "Cannot send the file because an error occured during the process.", "Failed", JOptionPane.ERROR_MESSAGE); return; } } System.out.println(fileTransfer.getFileName() + "has been successfully transferred."); System.out.println("The Transfer is " + fileTransfer.isDone()); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } } public static void main(String args[]) { FileSelectionMainGUI obj = new FileSelectionMainGUI(); obj.createGUI(); obj.login("senderjabberid", "password", "jabber"); } } 

Now the code for the receiver: (ruff is not suitable for gui, etc.)

 import java.awt.Color; import javax.swing.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.File; import java.text.DecimalFormat; import java.util.ArrayList; import java.util.logging.Level; import java.util.logging.Logger; import javax.swing.JButton; import javax.swing.JComboBox; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JTextField; import javax.swing.tree.DefaultMutableTreeNode; import org.jivesoftware.smack.ConnectionConfiguration; import org.jivesoftware.smack.Roster; import org.jivesoftware.smack.RosterEntry; import org.jivesoftware.smack.SASLAuthentication; import org.jivesoftware.smack.XMPPConnection; import org.jivesoftware.smack.XMPPException; import org.jivesoftware.smackx.ServiceDiscoveryManager; import org.jivesoftware.smackx.filetransfer.*; public class FileSelectionMainGUI { ConnectionConfiguration configGoogle = new ConnectionConfiguration("jabber.org", 5222); JFrame mainWindow; JLabel selectEmailLabel,selectFileLabel; JButton browseFilesButton,sendButton; JTextField browseField; JComboBox buddyListBox; JPanel contentPanel; Roster roster; FileTransferManager fileTransferManager; XMPPConnection connection; DecimalFormat transferringProgress = new DecimalFormat("#"); XMPPFileManager receiveManager; public void createGUI() { mainWindow = new JFrame("RECEIVER"); mainWindow.setLayout(null); mainWindow.setSize(700, 600); mainWindow.setLocation(100, 50); contentPanel = new JPanel(); contentPanel.setLayout(null); contentPanel.setBounds(0, 0, 700, 600); selectEmailLabel = new JLabel("Enter User Email ID"); selectEmailLabel.setBounds(80, 325, 150, 30); contentPanel.add(selectEmailLabel); selectFileLabel = new JLabel("Select File"); selectFileLabel.setBounds(96, 390, 150, 30); contentPanel.add(selectFileLabel); buddyListBox = new JComboBox(); buddyListBox.addItem(" [e-mail] "); buddyListBox.setBackground(Color.white); buddyListBox.setBounds(230, 325, 390, 30); contentPanel.add(buddyListBox); browseField = new JTextField(); browseField.setText("underline.png"); browseField.setBounds(230, 390, 220, 30); contentPanel.add(browseField); browseFilesButton = new JButton("Browse File"); browseFilesButton.setBounds(470, 390, 130, 30); contentPanel.add(browseFilesButton); sendButton = new JButton("Send File"); sendButton.setBounds(470, 490, 130, 30); contentPanel.add(sendButton); mainWindow.add(contentPanel); mainWindow.setVisible(true); } public void login(String userName,String password,String type_server) { connection = new XMPPConnection(configGoogle); XMPPConnection.DEBUG_ENABLED = true; SASLAuthentication.supportSASLMechanism("PLAIN", 0); try { connection.connect(); connection.login(userName, password); System.out.println("logged in..."); } catch(Exception e) { e.printStackTrace(); } new ServiceDiscoveryManager(connection); fileTransferManager = new FileTransferManager(connection); FileTransferNegotiator.setServiceEnabled(connection, true); fileTransferManager.addFileTransferListener(new FileTransferListener() { @Override public void fileTransferRequest(FileTransferRequest ftr) { System.out.println("got request"); try { IncomingFileTransfer transfer = ftr.accept(); System.out.println("status is:"+transfer.getStatus()); transfer.recieveFile(new File("testdoc.txt")); System.out.println("file recieved"); } catch (XMPPException ex) { Logger.getLogger(FileSelectionMainGUI.class.getName()).log(Level.SEVERE, null, ex); ex.printStackTrace(); } } }); } public static void main(String args[]) { FileSelectionMainGUI obj = new FileSelectionMainGUI(); obj.createGUI(); obj.login("receiverjabberid", "password", "jabber"); } } 

Both logged in successfully ... when I press the send button from the sender .. it does nothing without errors. just wait. Do you have a problem with the code? Am I doing something wrong?
