  1. POJava swing jTable not being updated
    text
    copied!<p>I built a jTable using NetBeans GUI, and I want to update it inside the constructor of the class. I'm planning to add a search option on the frame so the whole update idea is quite critical for me.</p> <p>My code:</p> <pre><code> public availableTrumps(TrumpistClient TC){ initComponents(); availableTrumpsTrumpistClient=TC; String result=null; String query="SELECT * FROM APP.TRUMPS"; result=this.availableTrumpsTrumpistClient.WritingReading("sql_select", query); if (result.contains("empty")){ JOptionPane.showMessageDialog(this, "There are now trumps to show."); } else if (result.contains("error")){ JOptionPane.showMessageDialog(this, "Error in the connection. Please try again."); } else{ int i; String []data = result.split("\r\n"); String [][] data2 = new String [data.length][]; for (i = 0; i &lt; data.length; i++) { data2[i] = data[i].split("&amp;"); } String[] columnNames = {"From", "To", "Departure Time", "Remaining Places", "Proposer", "ClosingTime", "Cost Per Seat" }; this.jTable1 = new JTable(data2,columnNames); this.jTable1.setPreferredScrollableViewportSize(new Dimension(500,100)); this.jTable1.setFillsViewportHeight(true); JScrollPane jps = new JScrollPane(jTable1); add(jps); jTable1.revalidate(); } } </code></pre> <p>The input two-dimentional array data2 is fine and validated. I added the last 5 rows of the code to see if they help with something. I don't know if they are mandatory and in any case I do not want to change the graphical properties of the jTable I built with the GUI (just the data in it). When I run the program, I see that the jTable remains empty. Why?</p>
