I have an issue with my client socket. For various tests I'm using port peeker as a server and listening on port 90. When I created GUI my self without netbeans designer I had no problem establish connection to port peeker, but if I use netbeans designer to draw a GUI I can't establish connection, it just freezes for 1 min. I tried debug and it always stuck on the Socket socket = new Socket("10.19.0.175", 90) line, then goes into catch (IOException ex). This problem occurs when I'm using domain environment in a work place, I tried at home and I had no problem, both ways worked fine. For tests I’m using basic connection. Try{ Socket socket = new Socket("10.19.0.175", 90); output = new PrintWriter(socket.getOutputStream(), true); in = new BufferedReader(new InputStreamReader(socket.getInputStream())); } Catch(IOException e){ }
Can you please provide more code?
Thank you very much for a quick respond. I have attached three files of my netbeans project. Problem occurs in action listener below and file name ClientView private void connectButtonActionPerformed(java.awt.event.ActionEvent evt) { when I click a button it goes as fare as socket = new Socket(ip, port); In a Debug mode I checked local variables and was fine, I even tried manually set ip address and port number socket = new Socket(“10.19.0.175”, 90);, but didn’t worked as well. package clientapplication; import java.util.logging.Level; import java.util.logging.Logger; import org.jdesktop.application.Action; import org.jdesktop.application.ResourceMap; import org.jdesktop.application.SingleFrameApplication; import org.jdesktop.application.FrameView; import org.jdesktop.application.TaskMonitor; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.IOException; import java.net.Socket; import javax.swing.Timer; import javax.swing.Icon; import javax.swing.JDialog; import javax.swing.JFrame; import java.io.*; import java.net.*; import java.awt.*; import java.awt.event.*; import java.net.ServerSocket; import java.util.Date; /** * The application's main frame. */ public class ClientView extends FrameView { public ClientView(SingleFrameApplication app) { super(app); initComponents(); // status bar initialization - message timeout, idle icon and busy animation, etc ResourceMap resourceMap = getResourceMap(); int messageTimeout = resourceMap.getInteger("StatusBar.messageTimeout"); messageTimer = new Timer(messageTimeout, new ActionListener() { public void actionPerformed(ActionEvent e) { statusMessageLabel.setText(""); } }); messageTimer.setRepeats(false); int busyAnimationRate = resourceMap.getInteger("StatusBar.busyAnimationRate"); for (int i = 0; i < busyIcons.length; i++) { busyIcons[i] = resourceMap.getIcon("StatusBar.busyIcons[" + i + "]"); } busyIconTimer = new Timer(busyAnimationRate, new ActionListener() { public void actionPerformed(ActionEvent e) { busyIconIndex = (busyIconIndex + 1) % busyIcons.length; statusAnimationLabel.setIcon(busyIcons[busyIconIndex]); } }); idleIcon = resourceMap.getIcon("StatusBar.idleIcon"); statusAnimationLabel.setIcon(idleIcon); // progressBar.setVisible(false); // connecting action tasks to status bar via TaskMonitor TaskMonitor taskMonitor = new TaskMonitor(getApplication().getContext()); taskMonitor.addPropertyChangeListener(new java.beans.PropertyChangeListener() { public void propertyChange(java.beans.PropertyChangeEvent evt) { String propertyName = evt.getPropertyName(); if ("started".equals(propertyName)) { if (!busyIconTimer.isRunning()) { statusAnimationLabel.setIcon(busyIcons[0]); busyIconIndex = 0; busyIconTimer.start(); } // progressBar.setVisible(true); // progressBar.setIndeterminate(true); } else if ("done".equals(propertyName)) { busyIconTimer.stop(); statusAnimationLabel.setIcon(idleIcon); // progressBar.setVisible(false); // progressBar.setValue(0); } else if ("message".equals(propertyName)) { String text = (String)(evt.getNewValue()); statusMessageLabel.setText((text == null) ?

Since you use Swing Application Framework for the GUI created in NetBeans, I guess you face the known issue caused by Swing App Framework setting the java.net.useSystemProxies system property. See http://www.netbeans.org/issues/show_bug.cgi?id=134745#desc16 for a workaround. Let us know in case it does not help. *** This issue has been marked as a duplicate of 134745 ***
