Error al generar applet RuntimeException
Publicado por Pablo (1 intervención) el 23/08/2017 20:31:53
Hola compañeros, un saludo a todos, vengo por estos rumbos porque necesito de su ayuda y experiencia, habitualmente no utilizo java, me enfoco mas en PHP y otros, pero tengo que hacer un sistema de control biometrico y para controlar el hardware necesito desarrollar un applet en java.
Ya tengo el código y si lo pruebo en netbeans funciona, pero al generar el jar y cargar el applet en un html, me da un error y no se como solucionarlo, el mensaje es el siguiente:
Espero puedan ayudarme, dejo el codigo de archivo principal para que puedan ver si alli tengo algun error:
