Hi!

dynamics.
Looking at your rule below, it is quite clear why that happens.
>(defrule alfalfa
> (evapo (temp "anual") (pluvial ?x&:(> ?x 600)&:(< ?x 1500)))
> =>
> ...)
The rule matches objects satisfying the follwowing condition (stated in
Java using your member variables):
m_temp.equals("anual") &&
((600 < m_pluvial) && (m_pluvial < 1500)) // 600 < m_pluvial < 1500
An object initialized with the default values (m_temp == null, m_pluvial
== 0) does not satisfy the conditions.
I have added the following constructor to your class:
public Datos(String temp, int pluvial) {
m_temp = temp;
m_pluvial = pluvial;
}
This constructor can be used from Jess as follows:
(definstance evapo (new Datos "anual" 1200) dynamic)
Running the engine after defining an instance using appropriate parameters
will make your rule fire.
I attached the modified Java class (Datos.java) and a Jess script
(datos.txt) that demonstrates its use. Just try it...
Greetings
Thomas
