Applet

¿Qué es un Applet?

Son aplicaciones que deben ejecutarse bajo un browser que soporte java.

A diferencia de un programa, un applet no puede ejecutarse de manera independiente, ofrece información gráfica y a veces interactúa con el usuario, típicamente carece de sesión y tiene privilegios de seguridad restringidos.

Un applet es un componente de una aplicación que se ejecuta en el contexto de otro programa, por ejemplo un navegador web.

Son multiplataforma es decir funcionan en Linux, Windows, Mac, y en cualquier sistema operativo para el cual exista una JVM (Máquina Virtual de Java) puede tener acceso completo a la máquina en la que se está ejecutando, si el usuario lo permite.


Ciclo de vida de un Applet

El navegador interpreta la página HTML donde se encuentra insertado el applet. Cuando encuentra la etiqueta APPLET el navegador descarga del mismo servidor donde se encontraba la página HTML el bytecode donde la clase indicada en la etiqueta APPLET.

Se crea una instancia de la clase que controla el applet.

El applet se inicializa (ejecución del método init ())

El applet comienza a ejecutarse (ejecucion del método start ())

El applet se visualiza en pantalla (ejecucion de método paint())

Cuando se abandona la página, el applet detiene la ejecución, ejecutando el método stop.

Cuando se regresa a la página que contiene el applet, se ejecuta el método start del applet y reanuda la ejecución.

Finalmente cuando se cierra la ventana del navegador, se termina la ejecución del applet, y se liberan todos los recursos ocupados por el applet antes de salir del navegador.

Durante todo el tiempo de vida del applet, éste continuará recibiendo llamadas de métodos por parte del navegador que le irán informando de los distintos eventos que se vayan produciendo (por ejemplo: maximizar y minimizar el navegador, abandono de la página HTML, etc).
