No lo veo por ningun lado ::), debe ser algo como esto: public static void main (String[] args ) { //aquiva el codigo que inicia la aplicacion :P }

SALU2 AmeRiK@nO man xD Jeje perdon, no lo habia visto, la proxima vez pon tu codigo con la etiqueta code=java. Mira, porque no prueba poniendo el metodo principal en una clase aparte y lo llamas así: public class Aplicacion { public static void main (String[] args ) { Calculos calculo = new Calculos(); calculo.setVisible(true); } }
Si la pones en diferente packete solo importas a Calculos.java y ya. salu2 amerikano
