Greetings:
I was wondering if you had a moment for a Java/Jess question?
If so, we are using Jess with Java, and our application passes in a JavaBean
that has the data needed to run against our rules. The original plan was to
have Jess put the results into a ResultBean but we just can't seem to figure
out how to cast a Value object to our own custom JavaBean (i.e.,
ResultBean), therefore we are stuck with a Value object that can't be cast
into another object type.
We are guessing that this may have something to do with the
external_address, but we don't know what a "Context" is or how to use it?
The documentation is vague to us on this topic.
We used this line of code to try to get our ResultBean back out: Value
rbValue = rete.fetch("JessResults");
And after this, we tried everything we could think of to get it to be a bean
again but nothing worked. We tried both passing in a Bean, and creating one
inside our .clp file, neither approach yielded us any success.
Below is the contents of our .clp file (reflecting our last approach):
(defglobal ?*count* = 0)
(defglobal ?*flag* = 0)
(defglobal ?*cdb* = nil)
(defglobal ?*rbean* = nil)
(set-reset-globals nil)
(defrule test-100
=>
(bind ?*rbean* (new mil.af.dtb.cabr.ResultBean))
(call ?*rbean* setvehFamily "Family2")
(call ?*rbean* setvehNumber "6450")
(bind ?antrad (fetch ANT-RAD-STATUS))
(if (neq ?antrad nil)
then
(bind ?antstat (call ?antrad getvalue))
(bind ?antnm (call ?antrad getname))
(printout t "--name--------- " ?antnm crlf)
(assert (input-1 ?antstat))))
(defrule compute-result-A
(input-1 ?a&:(eq 0 (str-compare ?a "passive")))
=>
(call ?*rbean* setsecAssessmentAnomaly 2 )
(call ?*rbean* setpriAA1ColorCode 1)
(printout t "--sending assesment 2 color 1" crlf)
(store JessResults ?*rbean* ))
)
(defrule compute-result-A1
(input-1 ?a&:(eq 0 (str-compare ?a "active")))
=>
(call ?*rbean* setsecAssessmentAnomaly 4 )
(call ?*rbean* setpriAA1ColorCode 3)
(printout t "--sending assesment 4 color 3" crlf)
(store JessResults "test"))
)
This .clp file should set the family name and the vehicle number at a
minimium.
Thanks in advance,
Joey
