Thanks for the immediate response.
It's obvious that I haven't understand something that must be simple...
First of all I have a JessUser.java file with some beans(such as:reportsLock
and specificUser
which is a User Class Object).
Then I have a JessCaller.java file which implements my userfunction that is
named 'calling':
public class JessCaller implements Userfunction {
public String getName() { return "calling"; } public Value
call(ValueVector vv, Context context) throws JessException { String type
= vv.get(1).stringValue(context); User
specificUser=(User)vv.get(2).javaObjectValue(context);
if(type.equals("DynamicReplanning")){ (new
DynamicReplanning()).executeDynReplanning(specificUser); } return
Funcall.NIL; }}
Finally I have a clp file,which I batch and run it in another java file, with
the rule:
(deftemplate JessUser (declare (from-class JessUser)))
(load-function JessCaller)
(defrule lockRule "Testing the rule." (JessUser { reportsLock == TRUE }
(reportsLock ?value))=> (printout t "ReportsLock: " ?value crlf)(calling
DynamicReplanning specificUser))
where i want to express that if reportsLock bean of JessUser class is
true,call(through calling variable) JessCaller file with a String
argument(DynamicReplanning) and a User Object argument(specificUser).
When I batch and run the clp file,I get the first argument right,but when I get
the java object:
'User specificUser=(User)vv.get(2).javaObjectValue(context);'
I have a java.lang.ClassCastException: java.lang.String cannot be cast to
ProtegeCode.User.
I imagine that the wrong part is in the defrule and I should declare
'specificUser' Object in another way,but I don't know exactly.
Thank You,
