Primero no se ejecuta dentro del explorador sino como si fuera una aplicacion de escritorio, es decir en una ventanita o como si fuera un programa aparte de explorador, se entiende?
Segundo en el propio explorador me da un error el cual copio desde la consola java aqui:
java.lang.ClassCastException: LeerArchivo.LeerArchivo cannot be cast to java.applet.Applet
at sun.plugin2.applet.Plugin2Manager.createApplet(Unk nown Source)
at sun.plugin2.applet.Plugin2Manager$AppletExecutionR unnable.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
Excepción: java.lang.ClassCastException: LeerArchivo.LeerArchivo cannot be cast to java.applet.Applet
LA PREGUNTA este codigo sirve tanto para compilar la aplicación para escritorio como para un applet? de no ser posible esto que tendria que cambiar en el codigo para que el applet corra dentro del propio navegador???
Desde ya muchas gracias!!!
PD: aqui les dejo el codigo que use para hacer el applet
