    <p>I am working on a swing application on client/server program for sending different types of files via java sockets. I have used the following link for reference: <a href="http://www.java2s.com/Tutorial/Java/0320__Network/TransferafileviaSocket.htm" rel="nofollow">File Transfer in Java</a></p> <p>I have modified the code as per my requirements as below:</p> <pre><code>public File file; public String fileName=new String(); String path=new String(); </code></pre> <p>Server Side Code:</p> <pre><code> try { File file=new File(path); ServerSocket servsock = new ServerSocket(12345); Socket sockFileName=servsock.accept(); FileOutputStream fout=new FileOutputStream(path); DataOutputStream dOut=new DataOutputStream(sockFileName.getOutputStream()); dOut.writeUTF(fileName); dOut.flush(); dOut.close(); sockFileName.close(); servsock.close(); } catch(Exception e) { JOptionPane.showMessageDialog(mainPanel, "file name: "+e); } try { ServerSocket servsock=new ServerSocket(12345); Socket sock = servsock.accept(); byte[] mybytearray = new byte[(int) file.length()]; BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file)); bis.read(mybytearray, 0, mybytearray.length); OutputStream os = sock.getOutputStream(); os.write(mybytearray, 0, mybytearray.length); os.flush(); os.close(); sock.close(); } catch(Exception e) { JOptionPane.showMessageDialog(mainPanel, "file sending: "+e); } </code></pre> <p>Client Side Code:</p> <pre><code> try { Socket sock = new Socket("127.0.0.1", 12345); DataInputStream dIn=new DataInputStream(sock.getInputStream()); fileName=dIn.readUTF(); jLabel3.setText(fileName); dIn.close(); sock.close(); } catch(Exception e) { JOptionPane.showMessageDialog(mainPanel, "file name: "+e); } JOptionPane.showMessageDialog(mainPanel, "file is being recieved . . .

Actually the client and the server are both implemented on the same window using different buttons. </p> <pre><code>package samplefilesendrecieveclientserver; 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.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.BufferedWriter; import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.FileWriter; import java.io.InputStream; import java.io.OutputStream; import java.net.ServerSocket; import java.net.Socket; import javax.jws.WebService; import javax.net.ssl.SSLServerSocket; import javax.swing.Timer; import javax.swing.Icon; import javax.swing.JDialog; import javax.swing.JFileChooser; import javax.swing.JFrame; import javax.swing.JOptionPane; /** * The application's main frame. */ public class SampleFileSendRecieveClientServerView extends FrameView { public SampleFileSendRecieveClientServerView(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 &lt; 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) ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
