Thread: Java Applet not running

Thank you for your quick reply.

The Applet just doesn't run at all. It just throws there is error, but then no details are shown.

I'm importing these libraries:

import Arboles.*;
import Lista.*;

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;

The first 2 are 2 packages I've made which are in the .jar file.

Also, I wasn't able to find that Applet Viewer you mentioned. Any hint on where I can find that option?

Thanks in advance

Well, I removed the codebase attribute and the same thing happened. An Error with no details. Also, I've put several print to the code, but still, nothing appears.

This is the code for the text and images (in spanish, tho):

public class QQSM extends JApplet implements ActionListener
{
        //Attributes
	arbolRojiNegro pregs;
	AATree<Integer> probs;
	AVLTree opciones;
	Binario scores;
	SplayTree correcta;
	int contCorrectas = 0;
	int puntaje = 0;
	nodoRojiNegro nodoPreg;
	int nPregunta;
	ListaSimple listaMalas;
 
	JButton acceso,salir,puntajes,retroceder1,retroceder2;
	JButton opcion1,opcion2,opcion3,opcion4;
	JButton comodin1,comodin2,comodin3;
	ImageIcon imagen1,imagen2;
	JTextArea expresion,recorrido;
	JLabel pregunta,labelI,anuncio,labelPuntuacion,label1,label2,label3,label4,label5;
	JPanel Panel;
 
//MÉTODOS DEFAULT APPLET
	public void init()
	{
		//Text File Inicialization
		System.out.println("Inicia Lectura");
		Archivos archAA = new Archivos("AA.txt");
		probs = archAA.probabilidades();    //Returns a tree, for functional purposes
		Archivos archRyN = new Archivos("RyN.txt", expresion, recorrido); //(This is different for GUI reasons)
		pregs = archRyN.preguntas();
		Archivos archAVL = new Archivos("AVL.txt");
		opciones = archAVL.opciones();
		Archivos archBin = new Archivos("Binario.txt");
		scores = archBin.puntajes();
		Archivos archSplay = new Archivos("Splay.txt");
		correcta = archSplay.respuestas();
		System.out.println("Termina Lectura");
		archAA.close();
		archRyN.close();
		archAVL.close();
		archBin.close();
		archSplay.close();
	}
 
Archivos(String direccion) //Archivos (Text File) Constructor
	{
		try
		{
		archivo = new File(direccion);
		lector = new FileReader(archivo);
		bufferLectura = new BufferedReader(new FileReader(archivo));
		System.out.println("Se abrió el archivo "+direccion+" correctamente");
		}
		catch(Exception Ex){System.out.println("No se encontró el archivo"+direccion);Ex.printStackTrace();}
	}
 
The image portions:
 
		labelI = new JLabel();
		labelI.setIcon(new ImageIcon(getClass().getResource("imagen1.jpg")));
		labelI.setSize(900, 530);
		labelI.setLocation(0, 0);
 
		labelII = new JLabel();
		labelII.setIcon(new ImageIcon(getClass().getResource("imagen2.jpg")));
		labelII.setSize(600, 250);
		labelII.setLocation(0, 0);

All images and text files are included in the .jar compilation.

Ok. I'm really sorry about the Cross Posting rules, I wasn't aware of it and will take into account in the future.

The thing of the Error with no details is that when I run the applet, the applet says "Error. Click for details", but when I click I just get this:


Java Plug-in 10.3.1.255
Using JRE version 1.7.0_03-b05 Java HotSpot(TM) Client VM
User home directory = C:\Users\Jose
----------------------------------------------------
c: clear console window
f: finalize objects on finalization queue
g: garbage collect
h: display this help message
l: dump classloader list
m: print memory usage
o: trigger logging
q: hide console
r: reload policy configuration
s: dump system and deployment properties
t: dump thread list
v: dump thread stack
x: clear classloader cache
0-5: set trace level to <n>
----------------------------------------------------

Generally, the exception stack trace would appear after the "------------------------------", but this is not the case and therefore I don't know what the error might be. And I've looked everywhere, but wasn't able to find a problem like this one.

Thanks everyone for your replies. I've finally solved the problem and it was a combination of several things:

The first one is that I was using internal packages, and for some reason it just didn't work that way so I just used the default package and it worked fine, but it gave the permission to read text files errors, which appeared weird to me because the .jar was already signed. After that, I just didn't complicate myself and sent the text files through parameters and voilá...it worked. Hope this works for someone in the future.

Thanks to everyone who contributed.
