Access exception text after exception event catch

Question

Dear all,
I am trying to handle the exception in the process, and I would like to check and log the details of the exception, because there are difference cause for the same exception.
I can catch the exception and prevent the process form stall, but would like to know how can I access the exception details text. (Like we done in Java code)
Thanks in advance
Regards
Bill

Here's my version of a simplified version of your code:
import java.awt.*;
import java.awt.event.*;
import java.net.UnknownHostException;
import javax.swing.*;
@SuppressWarnings("serial")
public class TestClass2 extends JFrame implements ActionListener
  JTextArea textArea;
  TestClass2()
    super();
    JPanel panel = new JPanel(new FlowLayout());
    textArea = new JTextArea();
    textArea.setPreferredSize(new Dimension(panel.getWidth(), 50));
    panel.setOpaque(false);
    getContentPane().add(panel, BorderLayout.NORTH);
    getContentPane().add(textArea);
    JButton clientButton = new JButton("client");
    clientButton.addActionListener(this);
    panel.add(clientButton);
    setLocationRelativeTo(null);
    pack();
    setVisible(true);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  @Override
  public void actionPerformed(ActionEvent e)
    if (e.getActionCommand().equals("client"))
      JOptionPane.showInputDialog(this,
          "Text", "Title",JOptionPane.QUESTION_MESSAGE);
      textArea.setText("should see text first");
      try
        try
          Thread.sleep(400);
        catch (InterruptedException e1)
        throw new UnknownHostException();
      catch (UnknownHostException ue)
        JOptionPane.showMessageDialog(this,
            "Error Text", "ERROR",
            JOptionPane.ERROR_MESSAGE);
  public static void main(String[] args)
    new TestClass2();
}These lines:
InetAddress.getByName(str);
connectToHost(InetAddress.getByName(str));cause a little delay in your program which I mimicked with a Thread.sleep. This may be why you think you should be seeing the text but aren't.
