JESS: pattern matching on string constants

[Satish boggavarapu]

Hi All,

How do i pattern match on string constants? or any constants?

I have a class A {
        public static final String STATE_DOWN = "down";
        public static final String STATE_UP = "up";
        public String getState();
        public void setState(String state);
}

now i want to pattern match like this

(defrule foo 
        (A (OBJECT ?obj) (state A.STATE_DOWN))
        =>
        .......
)

Is that valid? Or i have to use some thing like 

(defrule foo 
        (A (OBJECT ?obj) (state ?state))
        (test (str-compare ?state A.STATE_DOWN))
        => 
        .....
)

Thanks in Advance
