Я разрабатываю демо-приложение с использованием GwtAI (Интеграция апплетов Gwt). Я включил все GwtAI-client.jar,GwtAI-core.jar. Я имею в виду http://code.google.com/p/gwtai/wiki/GettingStarted Ниже приведен код.Интеграция GWT-AI
FileUploadingApplet.class
@ImplementingClass(com.nextenders.appletImpl.FileUploadingAppletImpl.class)
@Height("60")
@Width("350")
@Archive("GwtAI-Client.jar,FileUploadingAppletImpl.jar")
@Codebase("applet")
public interface FileUploadingApplet extends Applet{
public void increment();
public void decrement();
public Object getCurrentValue();
}
FileUploadingAppletImpl.class
public class FileUploadingAppletImpl extends JApplet implements FileUploadingApplet {
JTextField m_fileNameTF = new JTextField(15);
String controlTransactionId = "";
JFileChooser m_fileChooser = new JFileChooser();
JPanel content = new JPanel();
FileWriter fstream = null;
long fileLength = 0l;
@Override
public void init() {
JPanel panelMain = new JPanel();
m_fileNameTF = new JTextField(20);
m_fileNameTF.setHorizontalAlignment(JTextField.CENTER);
m_fileNameTF.setText("0");
m_fileNameTF.setEditable(false);
panelMain.add(new JLabel("Current count : "));
panelMain.add(m_fileNameTF);
panelMain.setBorder(BorderFactory.createTitledBorder("CounterApplet"));
panelMain.setBackground(Color.WHITE);
getContentPane().add(panelMain);
}
public void increment() {
int currentCount = Integer.parseInt(m_fileNameTF.getText());
currentCount++;
m_fileNameTF.setText(currentCount + "");
}
public void decrement() {
int currentCount = Integer.parseInt(m_fileNameTF.getText());
currentCount--;
m_fileNameTF.setText(currentCount + "");
}
public Object getCurrentValue() {
return m_fileNameTF.getText();
}
}
NTFileUpload.java
private void createPanel(){
PopupPanel panel = new PopupPanel();
panel.setPopupPosition(500, 500);
panel.setHeight("600px");
panel.setHeight("900px");
final FileUploadingApplet fileUploadApplet = (FileUploadingApplet) GWT.create(FileUploadingApplet.class);
VerticalPanel panelMain = new VerticalPanel();
Button buttonInc = new Button("Increment");
buttonInc.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
fileUploadApplet.increment();
}
});
Widget widgetApplet = AppletJSUtil.createAppletWidget(fileUploadApplet);
panelMain.add(widgetApplet);
panelMain.add(buttonInc);
panel.add(panelMain);
panel.show();
}
Я следил за структурой пакета по ссылке. Но я получаю следующее исключение.
