Kindly bear with me as I explain my query... I am developing an Intelligent Tutoring System using Jess + Servlet + Jsp. It will perform following actions (implemented as rules):
1. if student has completed a given task within specified time then give him next task. else jess rules will decide a suitable feedback message for the student (e.g., hurry up!). 2. a student while solving a multiple choice question (maintained as a question fact) can attempt more than once till answers correctly. Here number of attempts will be passes from a JSP page to a servlet page. The servlet will modify the attempt_count SLOT in jess fact and the engine will run and decide next suitable action. a question fact initially is: (deffacts question_objects (question (object-name "eaxmple1.html") (type question) (lo-id 10302) (reqd-time 25) (prev-lo-id 10301) (next-lo-id 10303) (diff-level medium) (attempt-count (default 0))) (theory (object-name "theory1.html") (type theory) (lo-id 103) (reqd-time 45) (prev-lo-id 102) (next-lo-id 104) (diff-level easy) (status incomplete)) ) Now, dynamically, i want to update the first fact's attempt-count slot value. But I have no clue how to get hold of that particular fact to call modify() from Java? Please let me know if I should be more detailed.
