[Qt-jambi-interest] Difficulty getting started with jambi

[Jeff Copeland]

Hello jambi enthusists.  I'm taking my first steps into the world of
Qt with jambi, but I'm getting some errors I don't understand.

I'm able to run the demo by running the qtjambi.exe included in the
package I downloaded.  When I try to build and run a simple program I
get errors related to unpacking the OS specific jar file.

Setup:

JRE 1.6.0
Jambi 4.4
XP SP2

Sample code:
--------------
import com.trolltech.qt.gui.*;

public class HelloWorld
{
    public static void main(String args[])
    {
        QApplication.initialize(args);
        QPushButton hello = new QPushButton("Hello World!");
        hello.resize(120, 40);
        hello.setWindowTitle("Hello World");
        hello.show();
        QApplication.exec();
    }
}


Error output:
----------------

I have both the qtjambi-4.4.0_01.jar and the OS specific
qtjambi-win32-msvc2005-4.4.0_01.jar in the classpath.

Any ideas?  Is there some other dependancy I'm missing?

Many thanks in advance.
