I just wanted to start using Apache Commons Configuration, but the simple
try { config = new XMLConfiguration("data//tables.xml"); } catch (ConfigurationException e) { //e.printStackTrace(); }
gets me an Eclipse error message "No exception of type ConfigurationException can be thrown; an exception type must be a subclass of Throwable"
What did I miss?

I've got a panel "top" containing several "sub" panels, I add "top" to the contentPane of a JDialog and I want to set the size of that dialog according to the size of "top". I use a BoxLayout for "top".
I started with setting the dialog's size with fixed values - works
then I tried to get the size of "top" and wanted to use this, but I get zero as width/height.
Grateful for any hint!

Hey Rob,
I was lucky, I found a solution!
Just insert
JFrame.setDefaultLookAndFeelDecorated(true);
and you see a "metallic" frame including title bar!

But I saw images of "metal frames" and internal frames including their title bars are loking "metallic" too, so I wonder why my frame still looks like Windows XP.

Having this :
{ public static void main( String[] args ) throws Exception { UIManager.setLookAndFeel( "javax.swing.plaf.metal.MetalLookAndFeel" ); JFrame frame = new JFrame(); frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); frame.add( new JButton( "Test Look And Feel" ) ); frame.pack(); frame.setVisible( true ); SwingUtilities.updateComponentTreeUI( frame ); } }
I get a Windows XP Frame with a Metal Button in it.
How can I get a Metal Frame?

Thanks Mikko!
Using setters worked, overriding getPreferredSize, too, although the resulting layout is different.
Overriding getSize and/or getBounds didn't make a (visible) difference.

Thanks Craig,
but this didn't show a better result!

This will be boring for most of you but I simply don't get it:
I want to paint a JComponent of my own so I did this from what I understood:
public class ExpFrame extends JFrame { private static String WINDOW_TITLE = "Mal-Versuche"; private JPanel view; public ExpFrame (Dimension dim) { super (); setLayout(new BorderLayout()); setSize(dim); Dimension screenDim = Toolkit.getDefaultToolkit().getScreenSize(); setLocation( (screenDim.width - getSize().width ) / 2, (screenDim.height - getSize().height) / 2 ); setTitle(WINDOW_TITLE); setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); view = new JPanel (); view.setPreferredSize(new Dimension (200,200)); view.add(new Figur()); view.add(new JButton("klick")); add(view, BorderLayout.NORTH); } public static void main(String s[ ]) { ExpFrame frame = new ExpFrame(new Dimension (800, 600)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.pack( ); frame.setVisible(true); } private class Figur extends JComponent { public void paintComponent (Graphics g) { super.paintComponent(g); g.setColor(Color.BLACK); g.drawRect(10, 20, 30, 40); } } }
But only the button is shown not my rectangle.
What did I miss?

sorry, I wasn't precise:
the result of
(String) call.invoke( new Object[] { "IBM" } );
is "exception", so
System.out.println("Sent 'IBM', got '" + ret + "'");
produces "Sent 'IBM', got 'exception'"

Hi there,
this is my first step into webservices, so..
When executing this, I get an exception (ok, it's a response, but I'm looking for more).
What did I miss?
public static void main(String [] args) { try { String endpoint = "http://www.webserviceX.NET/stockquote.asmx"; Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress( new java.net.URL(endpoint) ); call.setSOAPActionURI("http://www.webserviceX.NET/GetQuote"); call.setUseSOAPAction(true); call.setOperationName("GetQuote"); String ret = (String) call.invoke( new Object[] { "IBM" } ); System.out.println("Sent 'IBM', got '" + ret + "'"); } catch (Exception e) { System.err.println(e.toString()); } }
Thanks for your help!

I'm sorry:
within the setValue method an internal frame is opened and the basis for the TableModel is manipulated. After the user closes that frame, the textfield is still there, the new cell content is hidden, the row deselected. Only after the selection of another row, the textfield disappears and the new cell content is visible.
So my guess is, "someone" didn't get the fact, that the table cell editing is finished and I probably have to explicitly call a "editingStopped" method, or send end equivalent event, or ...
Can you see my problem now?

Hi,
I want to edit a cell of a table, so I have this:
public class AttributeFrameCellEditor extends DefaultCellEditor { public AttributeFrameCellEditor (final JTextField tf, final String aoName, final String attName) { super (tf); delegate = new EditorDelegate() { public void setValue (Object param) {
Everything's fine, but how can I tell (Whom?) sth like editingStopped?
Now I have to select another row to get rid of the Textfield.
Looking forward to your help!

thanks Ilja, I'll use the Template Method.

ok, just to make sure I got it right:
I'm talking about a bunch of panels that look and behave the same, but the the underlying list models get their data in different ways, so the programmer always has the choice/problem to decide
a. which command he has to pass to the GenericPanel or
b. which SpecificPanel he has to use
Is there a difference?

I have several classes which differ only in one method, so I think of either using an abstract class and have several specialized classes which only implement the specific method differently or have several implementations of a command that is passed to the one common class.
Are there significant differences between the two approaches? pros and cons?
Thanks!
