Hello.
I get the next error:
Jess reported an error in routine >

I´m trying do:
(deffacts robots_ball
(yo_ball (fetch "difyo_ball"))
(yo_myport (fetch "difyo_myport"))
(yo_suport (fetch "difyo_suport"))
(comp1_ball (fetch "distcomp_ball1"))
(comp2_ball (fetch "distcomp_ball2"))
(comp1_yo (fetch "distcomp_yo1"))
(comp2_yo (fetch "distcomp_yo2"))
(comp1_miport (fetch "distcomp_miport1"))
(comp2_miport (fetch "distcomp_miport2"))
(comp1_suport (fetch "distcomp_suport1"))
(comp2_suport (fetch "distcomp_suport2"))
)
;;;
(defrule control-nulo
(declare (salience 1000))

(comp1_ball ?c1b)
(comp2_ball ?c2b)
(test (neq nil ?c1b))
(test (neq nil ?c2b))
?fase
=>
(printout t "Ninguno de los sensores es nil" crlf)
(modify ?fase(es "jugar"))
)
;;;

(modify ?mover(eje_x ?mpx)(eje_y ?mpy)(velocidad 1)(chutar 0))
(assert (portero))
)
;;;
And I´m calling from JAVA with:
for(i = 1; i length+1; i++){
cadena2= "distcomp_ball" + i;
Vec2 aux = new Vec2 ( teammates[i-1].x - ball.x, teammates [i-1].y - ball.y);
jess_engine.store(cadena2, new Value (aux.r, RU.FLOAT));
}
Then, if I use
;;;(test (neq nil ?c1b))
;;;(test (neq nil ?c2b))
I get the error as stated above and if i use without ;;; (comments), I get in
JAVA a fatal error and it doesn´t work:
Exception in thread "Thread-2" java.lang.NullPointerException

I don´t why is it going on!!! Any help or suggestion?
Thanks for all.
