Há algum problema em usar InternalFrames em um applet????

[Adriano 'Stanley' 0]

E ae pessoal. É o seguinte... tenho uma classe que fica responsável por lançar InternalFrames. Ela funciona como aplicativo perfeitamente! Mas ao chamá-la em um applet os InternalFrames não aparecem! Segue os códigos... se puderem me ajudar! :)

 

//esse é o método dentro da classe DesktopFrame que lança os internal frames:public void lancarMapa(){	   JInternalFrame frame = new JInternalFrame( 			   "Internal Frame", true, true, true, true );	   MyJPanel panel = new MyJPanel(); // create new panel	   frame.add( panel, BorderLayout.CENTER ); // add panel	   frame.pack(); // set internal frame to size of contents	   theDesktop.add( frame ); // attach internal frame	   frame.setVisible( true ); // show internal frame	   frame.setSize(500,380);	   frame.setResizable( false );	   frame.setMaximizable( false );}

import java.awt.BorderLayout;import java.awt.Container;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import javax.swing.JApplet;import javax.swing.JButton;import javax.swing.JPanel;public class appletJF extends JApplet{	private Container container;	private JButton botao = new JButton();	private JPanel panelPrincipal = new JPanel();		private DesktopFrame desktopFrame = new DesktopFrame();		/**	 * Construtor appletJF;	 *	 */	public appletJF()	{		//setLayout( new BorderLayout() );				//botao.setBounds(250, 10, 80, 40);		botao.setText("adicionar");		botao.addActionListener(				new ActionListener() // anonymous inner class				{  					//display new internal window					public void actionPerformed( ActionEvent event ) 					{						desktopFrame.lancarMapa();					} // end method actionPerformed				} // end anonymous inner class		);				panelPrincipal.add( botao );				container = getContentPane();		container.setLayout( new BorderLayout() );		container.add( panelPrincipal, BorderLayout.EAST );	}	}

Vlw pessoal!

 

Os erros que aparecem:

Ou melhor, pessoal, se alguém tiver um exemplo, por mais simples que seja; até mesmo de um internal frame vazio abrindo em um applet, se pudesse me enviar (adrianostanley@gmail.com) eu ficaria muito grato!!Obrigado!

É o seguinte mano , dá uma lida neste artigo que eu achei na net.Estou com o mesmo problema que você , pelo que eu decobri tenho que primeiro assinar o applet e depois configurar o java.policy dando permissão de acesso.No seu caso vai ser fácil pq este link dá permissão para uma url como você quer, no meu caso o erro é de diretório.Assinando AppletSe funcionar me avise..... http://forum.imasters.com.br/public/style_emoticons/default/thumbsup.gif

e ae rapaz... vlw! eu consegui assinar o applet de acordo com este e um outro tutorial usado.porém, o applet assinado fica armazenado em um .jar.como eu faço pra carregar esse .jar em um documento .html????? é diferente de chamar um .class!vlw rapaz!
