I packaged the project in a jar that is an applet and I want this applet to run here in the old firefox browser linux, however, it asks to select a main method, but Applet has no main method. How to make him perform?
package xxx;
import java.applet.Applet;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import java.awt.Button;
import java.awt.Graphics;
//import netscape.javascript.JSObject;
public class TesteApplet extends Applet {
public String conteudo = "";
public String formulario;
public String campo;
//public JSObject campoDoFormularioHTML;
//
public void init() {
formulario = getParameter("formulario");
campo = getParameter("campo");
ActionListener trataEventos = new ActionListener(){
public void actionPerformed(java.awt.event.ActionEvent e){
conteudo += e.getActionCommand();
// campoDoFormularioHTML.setMember("value", "" + conteudo);
}
};
Button b7 = new Button("7");
this.add(b7);
b7.addActionListener(trataEventos);
System.out.println();
Button b8 = new Button("8");
this.add(b8);
b8.addActionListener(trataEventos);
Button b9 = new Button("9");
this.add(b9);
b9.addActionListener(trataEventos);
Button b4 = new Button("4");
this.add(b4);
b4.addActionListener(trataEventos);
Button b5 = new Button("5");
this.add(b5);
b5.addActionListener(trataEventos);
Button b6 = new Button("6");
this.add(b6);
b6.addActionListener(trataEventos);
Button b1 = new Button("1");
this.add(b1);
b1.addActionListener(trataEventos);
Button b2 = new Button("2");
this.add(b2);
b2.addActionListener(trataEventos);
Button b3 = new Button("3");
add(b3);
b3.addActionListener(trataEventos);
Button b0 = new Button("0");
this.add(b0);
b0.addActionListener(trataEventos);
Button limpa = new Button("Limpa");
this.add(limpa);
limpa = new Button();
// limpa.addActionListener(new ActionListener() {
//
// public void actionPerformed(java.awt.event.ActionEvent e) {
// conteudo = "";
// campoDoFormularioHTML.setMember("VALUE", conteudo);
// }
// });
//
// JSObject objWin = JSObject.getWindow(this);
// JSObject objDoc = (JSObject) objWin.getMember("document");
// JSObject objForms = (JSObject) objDoc.getMember("forms");
// JSObject objForm = (JSObject) objForms.getMember("formulario");
// JSObject objElements = (JSObject) objForms.getMember("elements");
// campoDoFormularioHTML = (JSObject) objElements.getMember(campo);
// campoDoFormularioHTML.setMember("value", "");
}

See if the edits I made did not modify your intention in the question, I believe that thus, it becomes more objective. And see if your Applet has a method
init(), which would be the equivalent of themain.– user28595
yes, it does. But I want a solution just that.

I understand, but you’re passing on too superficial information so we can help. Remember that we don’t know how it works or how your application was coded. See if the jar has manifest file, and if it is pointed to the class of your Applet that has this method
init()– user28595
manifest? What do I put in it and where do I put it?
– Aline
Are you trying to run applet by where? Direct from the browser or via linux terminal? If it is via terminal, which commands are you using?
– user28595
good question not yet arrived in this part...but right in the same browser
– Aline
Your class is stretching from
java.applet.Applet? it would be interesting to add it so we can see if it’s a code error.– user28595
