Try setting the classpath

Try setting the classpath, not in build path

Have the below tag in the JNLP and give a try.
<j2se version="1.5" href="http://java.sun.com/products/autodl/j2se"/>

Then try registering a WindowListener object for all other windows/frames and in windowActivated() method of that class, close the two dialog boxes.

I am assuming that you are having a servlet deployed on Tomcat that reads the file data.

From Swing application, you have to open a URL Connection to that servlet and write the HTTP Post Request to that stream.

Use JDialog rather than JFrame, and no need to implement FocusListener.
Here is a small example..
public class FrameEx1 extends JFrame implements ActionListener { JButton button = new JButton("Click"); MyDialog myDialog = new MyDialog(this); public FrameEx1() { setSize(300, 200); setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); getContentPane().add(button, BorderLayout.SOUTH); button.addActionListener(this); setVisible(true); } public void actionPerformed(ActionEvent ae) { if(myDialog == null) { myDialog = new MyDialog(this); } myDialog.setVisible(true); } class MyDialog extends JDialog { public MyDialog(JFrame frame) { super(frame); setSize(100, 50); // setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE); } } public static void main(String[] args) { new FrameEx1(); } }

To make a column invisible, just delete that column from JTable - this would delete the column from VIEW not from the MODEL.
You can add/delete a column to the table as and when needed without affecting the Model.

Yes.
Check UIDefaults for InternalFrame.

You can change the height of a row programatically using setRowHeight(). I think you have to implement drag-drop for your requirement.

It is the problem with the renderer. What is the value you are setting in setText()?
I am facing a problem with Combobox renderer - even though I explicitly (programatically) set the selectedindex to -1 or selecteditem to null, combobox is displaying some value. How about you?

I think you have to set the background color in the TableCellRenderer

Hi,
I am getting a problem using Renderer for Combobox - even though I explicitly set the selectedIndex to -1 or selectedItem to null, it is still displaying some item in the list.
Please help me.
Thanks in advance.

For this, you should have 2 TableModels - The originalTableModel and the transposeTableModel.
In transposeTableModel, you have to refer the originalTableModel in the logic for transpose in methods you implement.

public void actionPerformed(ActionEvent actionEvent) { ... Runtime.getRuntime().exec("<realplay.exe path> \"<path of the file to be played>\" "); ... }
