Re: JESS: Error : Calendar or GregorianCalendar in Jess.

[Dusan Sormaz]

Yasir,

Jess does not interpret string as arguments for the set method. You need 
to specify each argument, like in:

(call ?futureCal set (Calendar.HOUR) 8)

where (Calendar.HOUR) is the jess call into static field.

Hai There,
I am having difficult time to use "Calendar" Class from Java API in jess,
I am planning to use this class my simple jess script. But i just got 
stuck on the seting up the date detail (e.g: Year) in jess.
Once I run following script on eclipse.

    (reset)
    (watch all)
    (import  java.util.Calendar)
    (bind ?futureCal  (Calendar.getInstance))
    (call ?futureCal set "Calendar.HOUR, 8")



But, i would have an error ;

    Jess reported an error in routine call
        while executing (call ?futureCal get "Calendar.HOUR, 8").
      Message: No overloading of method 'get' in class
    java.util.GregorianCalendar I can call with these arguments: (call
    ?futureCal get "Calendar.HOUR, 8").
      Program text: ( call ?futureCal get "Calendar.HOUR, 8" )  at
    line 5 in file /home/jess/workspace/HelloWorld/src/HelloWorld.clp.


It is saying the 'get' method is not under GreogorianCalendar class, 
but if i am referring to this 
<http://java.sun.com/j2se/1.4.2/docs/api/java/util/GregorianCalendar.html> 
, it is already inherited form 'Calendar' class.
Any suggestion about above error?
Thanks for the attention
