Dear everyone:
When I run the code as follow:
1: public void run() {
2: URL file = Test.class.getResource("Test.xwt");
3: t ry {
4: XWT.open(file);
} catch (Exception e) {
e.printStackTrace();
}
}

package test;

import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Event;

public class Test extends Composite {

public Test(Composite parent, int style) {
super(parent, style);
}
public void selection(Event event){
Button button=(Button)event.widget;
button.setText("It is ok");
}
}

the fourth line throws a exception which is as follow:
classNotFound "selection".
help me.thanks.

It seems your xwt file is missing.

I guess you have a proble class loader. You need to change the thread class
load before calling XWT.open()/load()

XWT.setLoadingContext(new DefaultLoadingContext(this.getClass()
.getClassLoader()));
