I have few error messages in Netbeans
I am coding in Java, using UNO component.
I tried a sample OpenOffice Add-on project for OpenOffice spreadsheet, with simple edit in code in
 [code]public void dispatch( com.sun.star.util.URL aURL,
                           com.sun.star.beans.PropertyValue[] aArguments )
    {
         if ( aURL.Protocol.compareTo("com.example.addon:") == 0 )
        {
            if ( aURL.Path.compareTo("Command0") == 0 )
            {
                            JOptionPane.showMessageDialog(null, "You clicked command 0");
                            System.out.println("I have clicked command 0");
                // add your own code here
                return;
            }
        }
    }[/code]

but got following error message in Netbeans, the .oxt file was able to be add in Extension manager in OpenOffice, but clicking on button in menu of open office
, made open office hang up. And on abruptly terminating open office from task manager, showed the following error message in output window of Netbeans.
