Hi all,

I have some set of rules which work on same Person object but depending on
whether a person is student/employee/Faculty, the rule will have dfferent
logic.

So, I've made 3 .drl files, one will have all the rules for students, other
for employee and then last .drl for faculty. All 3 .drl have same package
name (as the first statement in drl) but all rules are named differently.
When my rule engine starts, it reads these 3 drl files and adds them to a
single rule base, starts a new session, inserts person in working memory and
fires rules.

Now, my questions are...is there anything odd/wrong with this approach?
Secondly, I had some rules names same in different drl and when I changed
them ....then I started getting null pointer exception error..... during
parsing of drl files. Any idea why is that?
